Now part of Generac Power Systems, Inc., GenTran is the leading brand of manual transfer switches and accessories for backup power applications using a portable generator.  A transfer switch, now required by the National Electric Code, connects to the circuits in your electrical panel that you'll need most during a power outage, like a furnace, lights, well pump, television, garage door opener and more.  Consumers prefer GenTran transfer switches because our units are expandable, reconfigurable and provide installation versatility. Let us help you prepare for your next power outage.
