An electric stove is a household electrical appliance whose operation is based on the conversion of electrical energy into heat. It is intended for cooking. There is a wide variety of electric stoves produced by various manufacturers, including foreign ones. Therefore, when purchasing this product, make sure that you have a quality certificate.
Follow the rules
It is not recommended to make electric stoves themselves. Any electrical appliance, including an electric stove, under certain conditions, can become a source of electric shock and cause a fire. Proper connection of electric stoves to power sources eliminates these negative phenomena.
Preparatory work
Requirements to be met before connecting:
- Choose a place to install. The surface on which the plate is installed must be flat, solid, dry, horizontal. It is undesirable to be near water pipes and radiators.
- A circuit diagram for connecting an electric stove is required , which will include: protective equipment (circuit breaker or fuse), residual current device (RCD 30 mA), a plug connector (socket) with a grounding contact, a connecting cable (necessarily copper, consisting of three wires).
- The cross section of the cable conductors, the rated operating currents of protective equipment are calculated based on the power consumption of electric. energy electric stove. To perform such calculations and develop a scheme, you need to contact qualified specialists if you are not.
- Connection of electric stoves, in view of the rather significant power consumption of electric. energy, it is necessary to coordinate with the network organization, to el. the networks of which your object is connected (apartment, apartment building, office, etc.).
- Install and connect the equipment in accordance with the electric stove connection diagram. These works are carried out taking into account the requirements set forth in the rules for the installation of electrical installations (PUE). Of particular importance here is the laying of the connecting cable. For example, when installing a cable on a combustible surface, the latter should be in a metal hose or cable channel made of non-combustible material, the aisles in the walls are made in steel pipes or openings.
- The room in which the electric stove is located must be equipped with a grounding circuit (for grounding the electric stove casing).
Connection Order
Direct connection of electric stoves to electric the network is made only after commissioning, including:
- measurement of insulation resistance between live parts and the electric stove body;
- measuring insulation resistance and checking the integrity of the conductors of the connecting cable;
- measuring the impedance of the phase-zero loop;
- DC resistance measurement of the ground loop.
To perform these works, you need to contact specialized organizations.
Electrical stoves must be connected by electrical personnel with an electrical safety group of at least III.
All the requirements described above must be strictly observed. Independent connection of the electric stove is not recommended.
