Energy Meter in House Wiring Diagram with Connection Guide

Work / Installation (Inputs → Outputs)

The installation of an energy meter starts with the utility (phase and neutral) input lines. They are hooked up to the input terminals of the meter. The output side offers phase and neutral. The phase is wired to a main switch or MCB, and then directly to the distribution board, but the neutral is wired to the DB. Circuit breakers then send the electricity to lights, fans, sockets, and appliances via the DB. The electricity provider must provide good earthing and meter sealing. Any used wiring has to be of standard cable sizes and in accordance with local regulations.

Testing & Final Adjustments

After the wiring has been done, it is then tested to make sure it is operating safely. Inspect the tightness of the check meter terminals, check the input and output connections with a checker, and verify that the phase is not inverted. Turn the MCB on and ensure the supply of electricity to the distribution board is working correctly. Check individual circuits, switches, and sockets to ensure that they do not spark off or overheat. Check earthing with a continuity test. When loads are on, the energy meter should indicate the correct readings. Last stage modifications involve screw tightening, insulating bare wires, labeling circuit breakers, and sealing the meter in accordance with electricity authority requirements. This ensures long-term security and appropriate power measurement.
