How to connect the electricity meter?

Setting the meter is not easy. After all, you need to know how to connect an electricity meter. Connection of an electric meter in case of its replacement or installation in another place should be made only after the approval of this issue with a representative of the local branch of the power supply company. After you have received permission to install an electricity meter, you can safely proceed to an independent connection.

How to install an electricity meter

When installing an electric meter in another location forits location, it is necessary to choose a place that will be available for inspection of the meter and taking readings from it. Electric meters should be installed in a dry room in which the constant air temperature does not drop below 0 ° C.

It is possible to mount the meter onmetal, wooden or plastic flaps. As a rule, they are installed on panels or panels, as well as in niches of walls that have a rigid structure. The meter is installed at a height of 1.4-1.8 m from the floor so that it can be disconnected in case of emergency situations, if it is repaired or replaced. All meters before the installation and start-up are subject to strict inspection and sealing by the authorities of Energonadzor. To connect an electric meter, copper wires with a cross section of at least 2.5 mm2 are most often used, or aluminum wires of at least 4 mm2 cross section can be used.

Wiring diagram of the electricity meter:

The work on connecting the meter starts with itsinstallation on the housing shield and secure it there fastening, with the help of screw fastening. Deviation from vertical position should not be more than 1 °. After this, it is necessary to throw a jumper on its input contact from the phase contact. switch, by means of which your electric stove will be powered.

In case you do not have a cookerconnect this jumper to the nearest distribution board installed on the switchboard. Before the input contact of the meter itself, as a rule, the phase is supplied by a wire with insulation of red or white color.

It should be taken into account that the installation of wiresThe rules for the installation of electrical installations may only be carried out in a horizontal and vertical direction. One end of the conductor in the red or brown insulation is attached to the meter contact, and the other end is attached to the short-circuit breaker terminal. Appropriate contacts of all nearby automatic protective devices are connected by U-shaped jumpers, from wires of the same color, and then carefully tightened.

For the wiring of a "earth" (zero) core, usuallyapply wire in blue insulation. Next you need (according to the instruction to the electric meter) to find on it the output "zero" contact, to lay from it a piece of wire with blue insulation to the general "zero" bus, and then carefully fix it from two ends.

In the event that the body of the electrical board is made ofsteel, it must necessarily be grounded with a special grounding conductor that connects to the ground loop and is connected by a free edge to the zero-bus contact plate.

Now you know perfectly well how toconnect an electricity meter. The main thing in this difficult occupation is to do everything accurately and slowly. More precise instructions for connecting the meter can also be found on the Internet. We hope you will be able to understand this matter. But in case you suddenly do not understand everything, then it's better to use the services of specialists.
