How Does a Generator Transfer Switch Work

When a home generator is installed the electrician will install a safety device called a transfer switch. A transfer switch is designed to isolate power from the utility company from the power made by the backup generator.

When power from a generator is allowed to return to the grid – a condition called backfeeding – damage can occur to electrical systems and poses a serious risk to utility workers if they are making repairs.

Transfer switches are also designed to protect the home from potential electrical fires caused by short circuits and faulty electrical connections. If your installing a home generator, it’s important that the transfer switch be installed by a licensed electrician.
