The Importance of Generator
Automatic Transfer Switch Maintenance

Perhaps one of the most important components of your emergency power system, the automatic transfer switch can be the key to your back-up power supply. Your generator's automatic transfer switch is constantly monitoring the flow of power from your regular source, and upon any number of scenarios, will determine the need to switch to your back-up generator. A functional generator is useless if its back-up power cannot be utilized in an emergency situation.
