What cable is needed to connect an electric stove?
Indeed, it happens that when you buy an electric stove, there is no wire included. In this case, you should purchase and connect it to the device yourself. This is not difficult to do, especially with a detailed analysis of the topic in this article.

Which brand of wire for an electric stove is better to choose?
In practice, there are two types of best brands:
- VVG (durable in operation);
- VVGng - non-flammable.
Both are made of copper and hence are flexible. Connection is perfect. Special rubber acts as a shell for the first of them.
There is a film between the cores to protect against sticking, which can occur due to high temperature. The second product named above also has several cores, which are isolated and connected into a single shell. The very durable wire easily copes with various stressful situations.
This is a fairly practical model and is in high demand among consumers. In addition, the PVS (vinyl connecting) wire, although not used for wiring, is perfect for connection.
ATTENTION! You will need two wires for installation. That is, one will run from the outlet to the input unit, and the next one will run from the outlet to the electric stove itself.
What should the section be?
Cable cross-section for an electric stove - this issue should be given special attention, as it is of particular importance. First, let's figure out why this is needed. Firstly, the cross-section can determine the power that the cable must withstand.
It depends on the type of power supply, which can be single-phase or three-phase. It can be easily determined “by eye”. The first of them is a product with only three cores. And the other - with five.
And there is another factor that affects the indicator of this characteristic - the type of wiring. For a complete understanding, some calculations are given as an example:
- For a section of two millimeters 2 with wiring of copper conductors in a single-phase network the power will be equal to 5.7 kW.
- With the same indicators, but with a three-phase network, the value will increase to 9.8 kW.
- If you change the type of wiring and take aluminum in one phase, then the power indicator will be 4.6 kW.
- And in three phases - 7.9 kW.
IMPORTANT! If you choose the wrong cable when connecting the device, as well as its other parameters, there is a high probability of a fire.
Question about cable power consumption
What cable is needed to connect an electric stove? To get the energy consumption value, you need to multiply the voltage by the current. Accordingly, the higher the voltage value, the less current required to reproduce.
Typically, the most powerful electric stoves are models with ratings up to 8 kW. Often, low-power devices are connected to a single-phase network; it can be up to 5 kW. And on the contrary, more expensive - with 3 phases. The last of the presented options is most often in demand among home owners in the private sector.
ATTENTION! In old houses built many years ago, it is prohibited to connect electrical products to the network with a power higher than 3 kW, since they are not intended for this.
Which is better: CG or PVS
The second type is a vinyl connection wire; it more accurately matches the requirements that must be met when connecting. This is important so that there are no interruptions and the functioning of electric stoves proceeds positively. In addition, this model is quite flexible and resistant to environmental, possibly dangerous factors.
It has a reasonable price on the market. Therefore, it is considered the most rational choice.
Have you even heard anything about electrical wiring in particular and electrical engineering in general, at least at the level of legends and fairy tales? Are you not blowing on the light bulb?
That's not what the article is about. There are no recommendations on the most important issue, the choice of wire cross-section and rating of the switching device. One water...
