Frequently Asked Questions

What is a manual transfer switch?

A manual transfer switch is an electrical device used to safely switch a load between two power sources, such as a main grid and a backup generator, by manual operation.

Do I need a permit to install a manual transfer switch?

Yes, electrical work often requires a permit and must be performed by a licensed electrician to comply with local codes and safety standards.

What are the disadvantages of a manual transfer switch?

It requires physical presence to operate, which can delay power restoration during an outage compared to automatic switches.

What is a cheaper alternative to a transfer switch?

An interlock kit for circuit breakers or a simple plug-in generator transfer cord are lower-cost options, but they offer less protection and convenience.
