Transfer Switches

A transfer switch provides standby power to your critical load by reading a power outage, calling the stand-by generator to start-up and then transferring the critical load onto the stand-by generator until street power is restored.

Automatic Transfer Switches generally feed either a server room distribution panel or individual pieces of equipment including UPS and HVAC Systems.

The ATS is generally sized and designed when a generator is installed. There are occasions however when added distribution off of an existing generator is required, as when a second or upsized UPS system is installed.
