Earth Leakage Circuit Breaker wiring:

This diagram shows how to make earth leakage circuit breaker wiring. In this diagram, we use a single-phase energy meter, an SP MCB ( Single Pole Miniature Circuit Breaker ), and an ELCB ( Earth Leakage Circuit Breaker ). At first, we need to input power to the energy meter, then need to input phase to MCB from the energy meter. After that, we need to input phase connection to ELCB from MCB and input neutral connection from energy meter to ELCB. Then input neutral and phase wire to the load from ELCB. Now it’s ready for use.

Components used to make the Earth Leakage Circuit Breaker wiring:

01. Single Phase Energy Meter:

A Single-Phase Energy Meter is a sort of Watt-Hour meter. It consists of two Electromagnets. Single-Phase Energy Meter is also Popularly known as a watt-hour meter. One Magnet is called the shunt magnet Ml which is Mounted with a Pressure coil. The Pressure coil is a long coil Made of fine Copper wire which is connected across the Supply line. Single-phase energy meters are suitable for measuring single-phase AC current frequencies of 50/60 Hz, which are used for fixed indoor installations.

02. ELCB:

ELCB complete earth leakage circuit breaker works on earth leakage production. Usually, the ELCB circuit breaker has two cables Phase and Neutral if any load is directly connected to the earth without taking neutral from ELCB then the circuit breaker will trip automatically. Earth leakage circuit breakers are used in applications to prevent electric shock and electrical fire caused by a short circuit or overload in the control panel by automatically closing when leakage is detected.

03. SP MCB:

In single-pole MCB, Switching & Protection is Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, 15-20 amps. They are constructed with one Hot Wire and one Neutral wire. An SP switch is the most basic General-Purpose switch that you use to Control a light or another device from one location. These Switches have two Brass-Colored screw Terminals Connected to the hot Power source wires. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Electrical Circuit.
