What is an Automatic Transfer Switch?

A transfer switch is a panel that is wired into the premises electrical distribution system to allow a generator to be used. It detects a loss in power for the mains and initiates the generator to start up and provide power. It then waits until the power from the mains returns to normal. It then puts your premises back onto mains power and signals the generator to cool down and return to standby mode.

A generator equipped with an “Automatic Transfer Switch” will detect loss of utility power automatically and start the back-up generator and once utility power is restored will automatically switch back to “normal” power.
