What is a transfer switch for a generator?

By Bob Millaway, South Jersey Community Expert & REALTOR®

A transfer switch is a device that safely connects a portable generator to your home's electrical panel, allowing you to power selected circuits during an outage. It prevents backfeeding, which is dangerous for utility workers and can damage your generator. Manual transfer switches require you to flip circuits by hand; automatic switches work with standby generators. A licensed electrician must install the transfer switch.

Why It Matters

A transfer switch is the only safe way to connect a generator to your home. Improper connections risk electrocution, fire, and code violations.
