There are numerous brands of transfer switches, all somewhat different from each other, but in most of them, the basic principle is similar. Here are the steps to follow to install a manual transfer switch.

Firstly, decide at what place you want your transfer switch. It is advised that the transfer switch should be at least 18 inches from the load center. Switch off your main circuit breaker of your load centre. Then remove ¾-inch knockout. Through the knockout, insert the wires from the flex conduit. Tighten the locknut onto the load center so the wires can suspend freely. Next, place the transfer switch to the wall safely without manipulating the flex conduit.

For wiring the transfer switch to the load center, connect the transfer switch to the circuit breaker. Route both wires of the transfer switch close to the chosen circuit breaker. Install the red wire of the transfer switch into the circuit breaker, and place the black wire of the transfer switch and the hot wire of the circuit breaker into the load center. Remove 5/8-inch insulation from the black wire of the transfer switch. Insert these wires into a yellow wire connector, twist it tightly and push back the wires to the load center’s wiring compartment.

After following the above steps, replace the load center cover. Excluding the main circuit breaker, turn on the switch of all circuit breakers. Set all EmerGen switches in the line position.

Managing Load

If the generator has no sufficient wattage capacity, then all circuits cannot be used at the same time. Manage the loads by trying to eliminate overload conditions.
