Generator Transfer Switch
A transfer switch is a safe way to connect your home to a portable inverter generator during a power outage.
It allows for the entire home to be powered by the connected generator. A transfer switch should be installed
only by a licensed electrician to ensure the safety of family members, property and utility workers. Injury or
accident resulting from an improperly installed transfer switch could possibly void your homeowner's insurance.
A transfer switch can be either automatic, manual or a combination of both. For the home, a manual transfer
switch is a safe and convenient option. It can be configured to isolate the circuits that require power while
preventing the risk of harmful utility backfeed.
Sizing requirements depend on a few key factors. For starters,
determine what size power cord will be used. If you plan to use a 30 amp cord then select a 30 amp transfer
switch. A good way to pick your chord is to match it to the largest outlet on your generator. If there's a 50
amp outlet, then choose a 50 amp chord. Make sure the plugs on the chord to be used match up with the outlet
on the generator and transfer switch. There is a possibility that the ends may require different plugs.
Next, decide which circuits you plan to power. If you plan to utilize a 3000 to 5000 watt inverter generator
then maybe consider a 6 circuit transfer switch. Look for a transfer switch that includes a built-in wattage meter
so you can monitor the load and to make sure that the system is not overloaded.
The location of your electrical panel is usually where you would install the transfer switch. If your electrical
panel is located outside the home then most likely you would place your inverter generator near the transfer switch
and plug straight in. If your electrical panel is located within the garage, inside the home or a basement then
maybe consider running a hard wired power inlet box to the transfer switch from a convenient location on the
outside of the home.
