Induction cookers or panels are the result of the development of traditional kitchen appliances. Their main difference from others lies in the principle of work. If everything is clear with a gas-powered stove, the combustion of gas fuel leads to heating of the dishes and food placed in them. In an electric oven, heating is carried out due to the fact that the electric current passing through the heating element generates a certain amount of thermal energy.
The inductive panel works based on other physical phenomena. Cooking on such equipment is carried out using induction. The current passing through the turns of the inductive coil is converted into an alternating magnetic field. It heats the dishes due to the resulting vortex field.
In order for the stove to work for a long time and without any problems, the user will only need one thing - to strictly follow the requirements given in the instruction manual. This document describes the procedure for choosing a location for installing the model, the procedure for turning it on and operating it.
The main tool that is required to connect the device to the network is a screwdriver. To connect directly, you will need to purchase a certain amount of three-core power cable. Most often, a cable with a cross-section of 4 to 6 square meters is used. mm. The length of this cable should be sufficient to reach the panel connection point. As a rule, a 4-wire cable is included in the package. 2 wires, brown and black, are phases, a blue wire is “0”, and a yellow-green wire is ground. The ends of the wires must be stripped. On the back side of the product there is a comb into which the stripped wires are installed. The free end must be connected to the house electrical network.
So, the panel is connected to the network. After this process is completed, some models signal that everything is proceeding as normal and the panel can be turned on.
On the control panel, as a rule, there is a “start/stop” button, pressing which will turn on the device.
Before starting work, it makes sense to clean the surface from packaging residues and traces of adhesives that may have remained after production. By the way, in the first minutes of operation it may smell like burnt rubber. But there is no need to worry too much, this unpleasant spirit will soon leave.
For each individual zone, there are separate buttons on the control panel; in addition, some models have separate controls. Power can be set from 0 to 9.
The operating instructions describe in detail which power modes are optimal for boiling and which for heating or direct cooking.
After finishing cooking, you must turn off the panel. To do this, you can press the “start/stop” button or wait a certain time, after which the panel itself will go into standby mode.
To prepare food, you need to prepare the necessary products and, of course, dishes, more on that below.
Suitable for cooking on induction ovens use specialized utensils made of ferromagnetic materials. This is determined by the physical principle that underlies its operation. Eddy currents, which create heat in cookware, are most effective on ferromagnetic cookware. If the consumer has no desire to spend money on purchasing new dishes, you can buy an adapter, made in the form of a disk and placed on the burner, so you can use familiar kitchen utensils (glass, aluminum, etc.). This adapter will take on the action of eddy currents and heat up, transferring heat to the dishes installed on it.
IMPORTANT!
TO FIND OUT WHETHER THE SELECTED COOKWARE IS SUITABLE FOR USE ON AN INDUCTION OVEN, OR NOT A ORDINARY MAGNET WILL HELP. IT IS ENOUGH TO BRING IT TO THE Utensil, AND IF IT STICKS, THEN THE Utensil CAN BE USED FOR COOKING WITH SUCH EQUIPMENT.
The best solution is to use dishes with a thick bottom.
To make the cooking process easier, manufacturers are trying to install large quantity functions, and some of them, in fact, can bring certain benefits. For example, the Booster function, which allows you to transfer power from burner to burner. It makes it possible to take energy from a free burner. This allows you to cook food a little faster.
Warm mode– its presence allows you to leave cooked food on the stove, and it will not be able to cool down for a long time.
Emergency shutdown It will work when liquid gets on the hob. As a result, all burners turn off.
Some models offer users various modes that allow them to cook a chop or stew mushrooms.
In some cases, it becomes necessary to block the stove, for example, from small children who may play around with the control panel. On front panel There may be a button with a picture of a lock. After pressing it, the control of the stove will be blocked. To turn it off, you need to press two buttons at the same time, as a rule, these are the “plus” and “minus” buttons, after pressing you need to wait a certain time.
One of the main features of an induction cooker is its cooking speed. Everyone who uses it in everyday life celebrates it fast work. Let's look at this using the example of making ordinary scrambled eggs. So, on gas, scrambled eggs will be ready on average in 12–15 minutes; on an induction oven, the cooking time will take no more than 4 minutes.
Important!
For those who are just mastering this device, at first they must strictly follow the instructions indicated in the recipe books. And only after gaining some experience can you cook yourself.
An induction furnace is an electrical device and, accordingly, its operation must be carried out in accordance with safety measures for working with electrical appliances.
By following these tips, you can easily use induction hob, and it will last for a long time.
Kitchen appliances in Lately surprises with its diversity and technological innovations. In addition to the familiar gas and electric stoves and hobs, induction devices have also appeared relatively recently. What is it, what is its operating principle and what is interesting about this device - we will talk further.
To put it simply, an induction cooker or hob is an electrical device that works on the principle electromagnetic induction, known since the 19th century.
To explain it as simply and briefly as possible, the operating principle of an induction cooker is as follows:
That is, for the stove or hob to work, it is necessary Electric Energy, but such a kitchen assistant cooks food somewhat differently than a conventional electric stove.
Like any household appliance, induction cookers can have a different set of functions, but even the simplest device has touch controls and a basic display that indicates all necessary information, For example:
There is an opinion that the magnetic field emitted by the stove is harmful to humans. However, recent studies have revealed that the radiation power is too low to affect humans and is comparable, for example, to the radiation from a working hair dryer.
Like any household appliance, induction cookers have advantages and disadvantages. Let's look at them in more detail.

Suitable cookware for induction cookers can be easily identified by the box (there must be a spiral icon with the inscription “Induction”) or simply by placing a magnet on the bottom. If it is magnetized, then the utensil fits.
Separately, we should talk about the issue of savings. When choosing kitchen appliances, in particular a stove, the question often arises: “What is more economical?” It is impossible to answer this unequivocally.
If we consider from the point of view of the cost of acquisition, then a hob or stove with magnetic induction, even with the simplest functions, will cost 1.5–2 times more than a similar gas or electric one.
But we must not forget that such a device ultimately consumes less energy and allows you to use it rationally, controlling the heating and the time the dishes remain on the stove.
If consider human factor(they left the kettle turned off, the burner just turned on, etc.) and the cost of gas and energy, then the question “Which is better: electric, induction stove or gas?” - “induction” will definitely win.
As a rule, the operating instructions and other accompanying documentation are always found in the box with the equipment itself and contain recommendations for care and use and the main features of the unit.
Brief features of induction cookers:
Modern technology not only simplifies our life, but also makes it safe and economical. Induction cookers are a modern and high-tech kitchen assistant that fits perfectly into any interior, is laconic and does not take up much space.
The operating principle of induction cookers and hobs, as well as some of the nuances of use, are discussed in the video presented in this article.
To understand what an induction cooker is, imagine the following situation. When you are ready to cook, you turn on your electric stove and pour water into the pan. At this time, your restless baby runs into the kitchen and accidentally grabs the hob with his hands. In the case of a conventional electric stove, it will end in a burn, but if you have an induction stove, the baby will not even feel the pleasant warmth.
The surface of the induction hob remains cold until a pan is placed on it.
An induction hob is safer than a glass ceramic hob or a conventional hob. cast iron pancakes. The operation of the device is based on the phenomenon of electromagnetic induction - the occurrence of electric current in a closed circuit due to a change in the magnetic flux passing through this circuit. Thanks to the English physicist Michael Faraday, the whole world knows about the phenomenon of electromagnetic induction. The development of the use of electromagnetic induction began in 1831, when Faraday made his discovery. Now it is quite difficult to imagine modern life without transformers - they are used at every step. An induction hob or induction cooker is the same transformer. The surface of the plate is glass-ceramic. Below it there is an induction coil, under which an electric current flows with a frequency of 20-60 kHz. The induction coil is the primary winding, and the cookware that is placed on the stove is the secondary winding. Induction currents are supplied to its bottom. The dishes heat up, and therefore the food in them. The pot or frying pan heats up, and the glass-ceramic surface, which is located between the heating element and the dishes, is heated by the dishes.
With induction heating, heat losses are minimal, and the heating rate of the cookware is significantly higher than that of stoves and hobs of other types (including hobs with halogen heaters). Thus, the heating efficiency of a glass-ceramic surface is 50-60%, gas stove– 60-65%. Induction heating has an efficiency of about 90%.
The operating principle of an induction hob is simple and effective.
Induction hobs appeared in family kitchens in the 80s of the twentieth century. It was then that mass production of such slabs under the AEG brand was launched. The first induction cookers were very expensive. But they were not in great demand, not only because the device was expensive, but also because users were extremely wary of innovations in the field of cooking. Now that housewives already know well what an induction hob is, reviews of these stoves are rather positive. But there are people who believe that induction has no place in the kitchen. Perhaps doubts arise because cooking on such stoves requires special utensils with ferromagnetic properties.
You don’t have to go to any specialized stores to find dishes with ferromagnetic properties. And there is nothing hazardous to health in the ferromagnetic properties of cookware. These are ordinary pots and pans that are attracted to a magnet. If he's attracted to you enamel pan, it is quite suitable for use on an induction cooker. But under no circumstances should you use aluminum or copper cookware. Dishes made of ceramics, copper, glass, and porcelain are also not suitable. But cast iron frying pans and stainless steel cookware are quite suitable.
Enameled cookware, stainless steel, cast iron are suitable for use on an induction burner.
The most famous manufacturers cookware for induction cookers - Fissler (Germany) and Woll. They produce not only pots and pans, but also stewpans, woks, frying pans, and ladles. Woll cookware is made by hand, it has a titanium-ceramic non-stick coating, the bottom thickness is 10 mm. The dishes from these companies are not cheap; they are designed for consumers for whom quality is more important than savings. High-quality cast iron cookware for induction hobs is produced by Hackman (Finland). If you are interested in cheaper cookware, pay attention to the companies Tefal (France), 4U Inox, Privilege Pro, Classica Inox, Pro Series. Pots and pans from the Czech company Tescoma are cookware with an induction bottom made of stainless steel at a price of around 2 thousand rubles.
Firstly, high heating rate. The bottom of the pan is heated, not the surface of the stove, therefore saving time for cooking. Secondly, electricity is saved. An induction hob consumes significantly less electricity than a conventional electric stove. After all, the current is not consumed to heat the coil, but only to create a magnetic field in the induction coil. Thirdly, induction cookers are safe. You will never get burned on their surface and will never start a fire, even if you forget to turn off the burner by removing the dishes from it. After all, without a pot or frying pan, nothing will heat up on the burner. Within a few seconds after the end of cooking, the very surface where the pan stood was not hot, but warm.
Food cooked on an induction cooker is absolutely safe, so all doubts can be cast aside
The surface of induction cookers automatically recognizes the presence of cookware on the burner, and also automatically adjusts to the diameter of the bottom.
The induction hob has several cooking programs. If any food accidentally falls onto the burner or stove surface, it will not burn because the surface does not heat up. The stove is attractive appearance and easy to care for. If something spills on it, you can simply wipe it with a soft cloth. Many housewives would like to see this miracle of technology in their kitchen, but there are also those who are sure that the induction cooker is unsafe.
Flaws induction panels The only thing is that when using the stoves you cannot use utensils made of aluminum or glass. It is not recommended to install the hob above other built-in metal appliances (for example, an oven). But the main disadvantage of an induction cooker is its high price compared to other types of cookers. Typically, average consumers cannot afford such a stove precisely because of its high cost.
An original and daring experiment demonstrates that only cookware heats up on an induction surface
The main criterion for mistrust on the part of consumers is the high price of induction hobs and their operating mechanism, which not everyone understands. There is an opinion that the magnetic field negatively affects human health. But manufacturers assure that the magnetic field created by induction cookers is low-frequency and cannot cause harm to the health of people, including those who wear pacemakers, but it is better for them to be safe and not get closer than half a meter to a working induction cooker. Or even stop using an induction cooker altogether.
The statement that an induction cooker is harmful is not without foundation. After all, a vortex magnetic field is created. However, the harm is not greater than the harm mobile phones(and we also press them to our heads when talking). The myth about the harmful radiation of induction cookers is the most popular “horror story” about this device. Food cooked on an induction cooker is absolutely not radioactive. Eddy currents that are created during the operation of the hob are locally limited by the body of the device. Already at a distance of 30 cm from the surface of the slab, the influence of the field is zero.
On Russian market, unfortunately no large selection induction cookers. The optimal price/quality ratio is the plates of the AEG-Electrolux concern. It looks no different from a regular electric stove with a glass-ceramic hob. The price of the device is 27-28 thousand rubles. Electrolux EKD 513502 X — This is a full-fledged free-standing stove, 50 cm wide, with an induction hob and oven. There is an indication of residual heating of the burners. After all, they heat up from the dishes and after finishing cooking they remain noticeably heated for some time. In the center they heat up to 90-100˚С, and at the edges - up to 25-40˚С. There are no other cookers with an induction surface on the Russian market. True, there is more Italian technology ILVE, but prices for induction cookers from this manufacturer start from 100 thousand rubles. Everything else is induction hobs, which can be purchased at prices starting from 17 thousand rubles. An independent built-in induction glass-ceramic hob is available in a wide range of household appliance stores. Let's look at the most popular models among consumers.
Under the BOSCH brand, several four-burner induction hobs are presented on the Russian market. These are the panels different designs with different numbers of heating zones. There are models where all the burners are induction, and there are also those where two of them are “regular” HiLight glass-ceramic burners.
The BOSCH PIN675N14E induction hob is attractive, convenient and efficient
When choosing an induction hob from BOSCH, pay attention to BOSCH model PIN675N14E, which has four induction burners, but the two burners on the left are combined into one. They can work as one heating zone (for large frying pans or saucepans) or as two different ones. This zone is called FlexInduction. Let us note another convenience of the induction panel from BOSCH - the PowerBoost function, which can be activated for each burner. This is a 50% increase in power to reduce cooking time. Additional power is “borrowed” from the adjacent heating zone. In addition, there is a function for recognizing dishes on the burner - electronic sensors “see” them, and they also determine its dimensions. If there is no cookware on the hotplate, the power will automatically turn off. A smart induction hob also “matches” the supplied power to the size of the cookware in order to save electricity.
The control of the BOSCH PIN675N14E hob is touch-sensitive. There is a digital indication of the degree of heating and 17-step power adjustment. The cost of such a hob is about 33 thousand rubles.
The price of the Hansa BHI64383030 model is about 13 thousand rubles. This is the most affordable four-burner induction hob. The maximum power of this model is 3.5 kW, so it is also suitable for those who live in an apartment with old wiring. Despite the fact that the total power of all burners is 4.5 kW, it is limited to 3.5 kW by the self-regulating EGO module. The connection of the Hansa BHI64383030 induction hob is single-phase, which is an undeniable advantage. No additional preparation of the electrical network is required - the hob operates using Plug&Play technology; to start using it, you just need to plug it into an outlet. We also note the Booster function (increasing the power of each burner by 50%), overheating protection (automatic shutdown), recognition function for the presence of dishes and their sizes, and a timer.
The induction hob Hansa BHI 64373030 has undeniable advantages
Hansa BHI 64373030 – combined induction hob. It has two burners with induction heating zones and two HiLight burners that reach maximum temperature in 7-10 seconds.
The Zanussi ZXE 66 X hob costs about the same as the aforementioned Hansa. But it has two induction burners and two regular ones (HiLight), while one of the regular ones has two heating zones, which makes it possible to use cookware of different diameters and not waste electricity. There is an “automatic boiling” function. The user can set the desired degree of heating and select the operating power; for a certain time, the burner operates at full power, and when the sensors detect that the boiling point has been reached and the contents of the pan boil slightly, the burner will automatically return to the power level set by the user, and the dish will continue to cook.
The hob control is touch sensitive, there is a function to block the surface control and auto shut off when overheated. In addition, there is a timer that gives an acoustic signal.
Combined induction Zanussi panel ZXE 66 X surprises with its versatility
In our country you can also buy induction surfaces from AEG, Electrolux, Neff, Gaggenau, Samsung, Siemens, Gorenje, Siemens, Kuppersbusch, Siemens, Whirlpool, Smeg, Kaiser, De Dietrich, CATA, Miele, ILVE. There are not only four-burner hobs on sale, but also two-burner, five-burner and single-burner hobs. There are also induction WOK burners, which can be a hob segment or separate element.
The connection parameters for the induction hob and installation requirements are set out in the instructions that come with the device. It is recommended to connect the hob to the power supply system via a separate cable from the electrical panel. In this case, it is necessary to install an additional socket fuse. The connection to the panel can be either without a socket or through a grounded socket of appropriate power. The hole in the countertop for the hob is cut out using a jigsaw, but you must first mark the location using a pencil and a template.
After the hole is made in the tabletop, the edges with a violation of the protective layer should be treated with a special product for chipboard tabletops - transparent silicone sealant. A seal is also needed to prevent moisture and small debris from getting under the hob.
When preparatory work completed, the hob can be fixed in place and connected to the electrical network. Use special fasteners. Check the operation of the induction hob by placing a pan filled with water on the hob surface. Do not forget that the dishes must have ferromagnetic properties (attract ordinary magnets).
The induction hob is very convenient, easy to keep clean, and the dishes prepared on it are worthy of the highest praise.
Induction heating technology in cookers and cooktops is one of the most advanced today. They ensure user safety due to the low heating of the burners. They save time spent on cooking thanks to the high efficiency of induction heating. They save energy. The only drawback of induction hobs is their high price; generally, such panels are still more expensive than conventional ones. If we're talking about about separately standing slab, there is also a problem with the assortment. But no one will argue that induction heating provides additional convenience, and the fact that you have to pay for them is quite normal. Let your kitchen be comfortable and modern!
Until recently, household stoves were divided only according to the principle of operation - gas or electricity, and when purchasing there were no questions about how this or that model worked. But today, with the development of new technologies and the improvement of household appliances, manufacturers offer consumers familiar units and modern modernized models.
Induction cookers are the result of modernization of familiar household appliances. It is worth presenting in more detail the facts about how they work and what they are. The physical action applies only to the hob; the oven is electric with thermal heating elements.
The operating principle of this type of equipment may seem strange, because during the heating process it is the dishes that heat up, not the burner. The secret lies in the use of a physical phenomenon in the operation of the equipment.
It uses the technology of inducing eddy currents on a mounted metal object. This result is created by magnetic fields of frequency from 20 to 100 kHz.
Externally, it is a glass-ceramic hob with touch-sensitive temperature controls. Cooking timers and panel lock buttons are installed on the equipment.
Using this technique involves purchasing special metal utensils. The stoves also work with conventional metal utensils, but then the energy consumption and cooking time may increase.
What is the secret of cookware designed for use on such equipment? The secret lies in the structure of the bottom of the pots or pans. The bottom of such dishes is thick and its structure contains a layer of ferromagnetic material.
The owner may already have such devices in her house. Modern designs are indicated by a special spiral sign, which means compatibility with induction.
Old-style cookware is also used on such equipment, and if there is no sign, then its suitability is checked by applying a magnet to the bottom. If magnetization occurs, then this specimen is suitable for further use.
Devices with induction heating technology, on average, are more expensive than glass-ceramic heating surfaces. Is it worth overpaying? And what benefits will the buyer receive after the acquisition?
Advantages:
In contrast to the advantages of induction heating, there are also negative distinctive features:
There are not so many disadvantages, and they all concern financial side. But once you invest in a purchase, you can save on electricity for several years.
Cookers using induction heating technology have not been in demand for a long time in the household appliances market. And the reason is not only the high price, but also myths and prejudices.
The opinion that the technology underlying the operating principle of the equipment can cause harm to the human body. People were afraid that the magnetic field created during work would affect internal organs. In order to destroy the false opinions that have developed regarding induction panels, manufacturers compared the power of the resulting fields from this device and from a household hair dryer, which housewives use quite often.
The results were incredible. The hairdryer creates a field with an indicator of 2000 micro Tesla, and the hob - 22 micro Tesla - this is almost 10 times less! The strength of such a magnetic field cannot affect human health in any way!
People believe that any metal object can cause the burner to turn on and will heat up. This statement is not true.
As already mentioned, for work you need dishes that can be attracted by a magnet, but not all metal kitchen appliances have such qualities.
Sensors built into the plate design are configured to minimum diameter– 8-12cm. If the area of the heated surface is less than this indicator, then heating will not occur.
It is a misconception that the installation of a built-in panel cannot be above other devices or any metal surfaces.
Yes, the electromagnetic field created, in theory, leads to heating of objects on the surface and below it. This statement took place at a time when induction cookers were just beginning to be produced.
Modern models are equipped with a magnetic heat sink located at the bottom of the hob body. Its purpose is to block the penetration of magnetic fields through the lower part of the case.
Therefore, today manufacturers produce both combined models with ovens and those designed for installation in kitchen furniture over dishwashers or other equipment.
Like other household appliances, induction surfaces have characteristics that can influence the choice of a particular product in a store - these are design, functional characteristics, manufacturer’s name and price.
Design features when choosing stoves include: free-standing equipment in combination with an oven, tabletop or built-in models, size and shape of the equipment.
Freestanding household appliances, with induction heating, are rarely found in stores today, no more than 20 copies. Such models do not require additional purchase of ovens, are installed in any free space, do not take up space on the table, and are not built into the countertop.
Tabletop units are equipment with one or two burners, no more. They do not require additional installation conditions; in addition, some models are designed to operate at a voltage of 220W.
The range of built-in models of induction appliances presented in stores is incredibly wide. In online stores the number of models offered is even greater. Built-in models look attractive when combined with the entire kitchen arrangement and do not require a separate installation space.
The shapes of household appliances are the usual square or rectangular, but there are also hexagonal built-in models. The sizes can match the wishes of any consumer. The main condition before going to the store to make a purchase is to accurately measure the place where the unit will be installed.
Functional characteristics that require attention when choosing:
The cost of induction cookers is influenced by: manufacturer, functionality, size, number of burners, design, construction. Before you go shopping, you need to clearly define the requirements for the future basic household appliance in the kitchen.
It is not rational to rely only on the popularity of the manufacturer; equipment manufacturers may not advertise their products. Price orientation may not be relevant either. Stores set prices depending on their desires.
It would be correct to take into account the functionality of the model you are interested in. Additional functions increase the price, so it’s worth considering the need for this or that option in your everyday life.
An induction cooker is a device that operates using power from an electrical network. And like any other electrical equipment, it must be used with precautions.
When purchasing a new induction cooker, you should not rush to plug it into one of the available outlets. IN in this case first of all, it is necessary to determine the possibility of connecting a given household electrical appliance to a particular section of electrical wiring and select the most the best way its connections. Let's consider the question of how to connect an induction cooker.
It should be noted that before purchasing an induction cooker, it is necessary to clarify what load limit is determined for the apartment (house) and evaluate the possibility of using a particular induction cooker, taking into account its maximum power consumption.
A tabletop induction electric stove, as a rule, has a cord and a plug for connection to a regular household outlet. That is, in this case there is no need to purchase an additional cord and plug to connect the electrical appliance. But in this case, it is very important to choose the right outlet to turn on the electric stove.
Very often they make a mistake - they plug the electric stove into one of the free sockets, without taking into account its load capacity, that is, the amount of load that can be plugged into a given socket.
In the best case, one of the circuit breakers in the electrical distribution panel will turn off - as a result of an overload in one of the electrical wiring sections. But if the wiring is not properly protected, for example, if several wiring lines are connected to one circuit breaker, an overload will damage the wiring.
Therefore, before you start using an electric stove, you need to find out its maximum power consumption and make sure that this electrical appliance can be plugged into one of the available outlets. Power consumption is indicated in watts (W) or in kilowatts (kW) in the passport on the body of the electric stove, as well as in technical specifications in the operating instructions for this household appliance.
It should be remembered that an ordinary household plug socket is designed to turn on household electrical appliances with a rated power of no more than 3.5 kW, which corresponds to a load current of 16 A. That is, if the power consumption of the electric stove does not exceed given value, then it can be plugged into this outlet.
First, you need to know which cable is plugged into the outlet and how it connects to the rest of your home's wiring. The cable feeding the outlet must have a cross-section of at least 2.5 square meters. mm.
If the cable is connected directly to the home distribution panel, then such wiring line can withstand the current of the household outlet; a circuit breaker of the required rating can be installed to protect such wiring line. This option is most preferable in terms of reliability.
The second common option is that the cable powering the outlet is connected in a junction box. In this case, you need to take into account the loads of other outlets connected to this junction box.
The cable that runs from the main distribution panel to the distribution box must withstand the total load of the outlets powered from it. Therefore, if the load on the induction cooker is an overload for a given section of the electrical wiring, then to turn it on, you should select another outlet of the appropriate load capacity.
Secondly, it is necessary to assess the technical condition of the electrical wiring. If the electrical wiring is in poor condition technical condition, then when a new load is turned on, it may be damaged (See -). In this case, it is necessary to pay attention to the condition of the cable, in particular its insulation.
A cable with copper conductors is preferable, but if old aluminum wiring is installed in the house, then there is a high probability that such a cable cannot withstand the permissible load.
It is also necessary to pay attention to the condition of the electrical wiring contact connections at the cable connection point in the home distribution panel, socket, as well as intermediate contact connections in the junction box.
For connecting an induction cooker to the network. For safe operation of an induction cooker, it must be grounded, that is, plugged into an outlet with working grounding.
You also need to pay attention to the condition of the outlet. If the plug of an electrical appliance does not make good contact with the socket connectors, then the socket must be replaced.
An induction hob has more power; it is plugged not into a regular household outlet, but into a power outlet rated for a current of more than 16 A.
The power socket for connecting the induction cooker is selected according to its load. The total load of an induction cooker can be on average 25-32 A, depending on the number and power of burners.
To power the induction cooker, in this case, an individual electrical wiring line must be laid. The cable cross-section depends on the load of the induction cooker: for a current of 25 A, a copper cable with a cross-section of 4 square meters should be laid. mm, for a load of 32 A - 6 sq. mm.
For safe operation of the induction cooker, the electrical wiring must have working protective grounding. That is, for a single-phase network, a three-core cable must be connected to connect the induction cooker. Accordingly, the purchased power socket and plug set must also have a third grounding contact.
If it is not possible to purchase a power outlet of the required power, then alternative option You can connect an induction hob installed in the installation box. The terminal block must be able to withstand the rated current of the induction cooker connected to it.
As for the cable through which the induction cooker is connected, in this case it all depends on the configuration. If the power cable is included, then it is enough to connect it to the terminal block directly on the induction cooker, and then to the purchased power plug or in the terminal block, depending on the chosen method of connecting the induction cooker.
If the cable is not included, it must be purchased separately. When purchasing a cable, you must pay attention to its cross-section - it must correspond to the load being connected. It is necessary to purchase a flexible three-core cable with a cross-section of 4 or 6 square meters. mm for rated currents of 25 and 32 A, respectively.
To avoid errors, it is recommended to connect the cable to the stove itself, as well as to the plug: brown or black - phase conductor, blue - neutral conductor, yellow-green - protective grounding conductor.
If the cable is already connected to the terminal block of the electric stove, then you need to check that it is connected correctly. The following terminal markings are usually indicated on the terminals of an induction cooker:
L - phase output or L1, L2 (L3) - phase outputs for two-phase (three-phase) connection;
N - zero output;
PE is the connection point for the protective grounding conductor.
Two-phase and three-phase connection of an induction cooker
Certain types of induction hobs may provide a two or three-phase connection to the electrical network. If the house is installed, then such an electric stove is connected, as the manufacturer recommends, to two or three phases of the electrical wiring with a four or five-core cable.
The electric stove is connected to a single-phase household electrical network with a three-core cable, and special jumpers between the phases, which are usually included, are installed in the terminal block on the induction cooker. If there are no jumpers, then the connection to two or three phase terminals is made with a wire of a cross-section corresponding to the load of the electric stove.
It should be taken into account that if the kit includes a cable for two- or three-phase connection, then it is not designed for single-phase connection, since when the induction cooker is connected single-phase, the load on the phase conductor increases to the total load of all phases.
Therefore, when using a four (five) core cable to connect to a single-phase network, two (three) phases on the plate are connected to the cable cores, and at the other end of the cable, when connected to a plug or terminal block, the phase conductors are short-circuited with each other and connected to one phase of the electrical network . Or a new three-core cable is purchased that has sufficient load capacity for single-phase connection electric stoves
The process of connecting an induction hob with an oven is no different from connecting one induction hob. The only difference is the higher power consumption, since in addition to the induction hob, oven power is added. Accordingly, it is necessary to select the correct cable cross-section, as well as a set of power sockets and plugs to connect the electric furnace to the network.
There are types of induction cooktops with ovens that limit the maximum power consumption by turning off one of the burners when the oven is in use. That is, you can operate all the burners of an induction cooker at the same time, but when you turn on the oven, the ability to turn on one burner is blocked. This option is most suitable for houses with a limited power limit, which does not allow the operation of sufficiently powerful electric stoves.
Protective devices
When connecting an induction cooker, it is very important to choose the right protective devices. To protect the induction cooker, as well as the power supply wiring, a circuit breaker is installed. Rated current circuit breaker selected based on the power of the induction cooker. In this case, the closest one is selected higher value current, but the characteristics of the electrical wiring are also taken into account - it must protect all elements of the electrical wiring.
To ensure the safe operation of the induction cooker, a switchboard is installed in the distribution board, which protects against electric shock, as well as fire in the event of current leakage through damaged insulation. The RCD must be designed for the rated current, taking into account the possible load on the electrical wiring lines.
For example, if a 32 A circuit breaker is installed on the line, then the RCD must be designed to operate at a higher rated current- 40 A, since the thermal release of the circuit breaker does not turn off immediately when the current exceeds 32 A, but after a certain time delay. To protect a person from the negative effects of electric current, the differential current of the residual current device must be no more than 10 mA.
As an alternative, it is possible to use a combined device - which performs the functions of the two above protective devices.
