Founded in 1982, GenTran Corporation is the nation’s leading manufacturer of generator transfer switches for residential and small commercial standby power applications. A transfer switch makes using a generator more safe and convenient – no matter what size. The National Electrical Code mandates that a transfer device be installed with ALL standby power systems including portable generators. During a power outage, a transfer switch safely isolates those circuits using generator power from the rest of the house, so the danger of back feeding the electrical utility is eliminated. By installing a transfer switch with your load center and connecting a generator to the transfer switch, you can run selected appliances such as a furnace, well pump (which cannot be run with standard extension cords), sump pump, refrigerator, television, computer and more during a power outage, depending on the capacity of your generator.

With an installed base of over 1 million units,  we are proud of our reputation as America’s preferred brand – asked for by name, and recommended by more contractors.  GenTran Corporation has been family-owned and operated since 1982.

We never stop in our quest to bring value to our customers during power interruptions. GenTran offers the best value in manual and fully automatic transfer systems designed for generators up to 50 kilowatts. And while a transfer switch is at the core of any backup power system, we also manufacture accessories to fulfill virtually any installation requirement. 

If you are worried about power outages or live in an area that is susceptible to severe weather, GenTran can help you safely power your home or business with a generator. The best way to ensure reliable and continuous power is with a GenTran transfer switch system and a generator.
