A 3-phase wiring schematic is a wiring plan for a home showing how to connect a 3-phase consumer unit from a utility pole to a 3-phase energy meter and a 3-phase distribution board. Homeowners install a 3-phase electrical meter when they exceed the limit for a single phase meter.
There are different requirements that are taken into account for a correct execution of the schematic. A 3-phase meter is recommended for domestic areas. It is necessary to disconnect the power before the installation of the meter. Using proper cable size is important. A person should read to manual correctly and must worker under the watch of a professional electrician or hire one.
