Manual transfer switch wiring:
This diagram shows how to make Manual transfer switch wiring. In this circuit, we use a magnetic contactor, an SP MCB ( Single Phase Miniature Circuit Breaker ). First, we need to input phase connection to SP MCB from the Grid line. Then input neutral and phase connection to Magnetic contactor. Then input phase connection to SP MCB from the generator line. Then input neutral and phase connection to Magnetic contactor. Now this circuit is ready for use. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the Manual transfer switch wiring:
01. Magnetic Contactor:
A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.
02. 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.
