ASCO Power 300 Series Automatic Transfer Switches

ASCO Power 300 Series Automatic Transfer Switches in California

It’s important to know that the ASCO Power 300 Series Automatic Transfer Switch continuously monitors incoming utility power. When it detects a voltage interruption or unacceptable fluctuation, it automatically signals the generator to start. Once the generator reaches proper operating speed and voltage—typically within seconds—the transfer switch moves the building load from utility power to generator power. When utility power is restored and stabilized, the switch transfers the load back to the utility source and initiates generator cool-down. This fully automated sequence protects critical operations without manual intervention. Due to this efficiency, Leddy Power Systems, Inc. offers this generator to businesses in California that need electrical output. Are you interested?
