Full Answer

There are both manual and automatic transfer switches. However, when it comes to installation, the procedure is the same. Next to the existing main power panel where the circuit breakers are, fix the transfer switch to the wall. Ensure that power to the premise is turned off from the main power panel. Using appropriate cable size, do the connection between the transfer switch and the circuit breakers in the main power panel, instructs ThisOldHouse.com.

Drill a hole of 1.5 inches in diameter through the wall. Do this from outside. Still from the outside directly on top of the hole, fix the electrical box on the wall using screws. Ensure a cable is running from the transfer switch to the box through the hole. Connect the cable to the electrical receptacle. The receptacle usually comes with the transfer switch. Screw the receptacle to the box from outside. From inside the house, connect the transfer switch to the cable coming from the receptacle.

Test to ensure the system is functioning properly, instructs ThisOldHouse.com. With the main power still off, start the generator and plug it into the outdoor receptacle. With the switch on the transfer switch, flip from the main power to the generator. Confirm to ensure that the generator is sending power to the necessary circuits.
