Transfer Switch Repair in Denver

The transfer switch is the component that makes a backup generator actually work as a backup. Without it, a generator is a separate power source with no connection to the home's electrical system. With it, the generator connects to the house safely, the utility connection isolates so power can't feed back onto the grid, and the circuits the homeowner wants backed up get powered automatically. It's the critical link in the system, and it's the piece that fails silently until a power outage reveals it.

There are two types of transfer switches used in residential generator systems. A manual transfer switch requires someone to physically throw the switch to connect the generator to the home when the power goes out. An automatic transfer switch, which is standard on standby generator installations, monitors utility power continuously and initiates the generator start sequence within seconds of detecting an outage, then transfers the load to the generator automatically without anyone having to do anything. When utility power returns, the automatic transfer switch transfers the load back and shuts the generator down.


Transfer switch repair comes up in a few specific situations. An automatic transfer switch that isn't responding to a power outage the way it should. A unit that's transferring erratically or producing error codes on the generator control panel. A manual transfer switch with contacts that have corroded or a mechanism that's seized from inactivity. Transfer switch problems frequently get misdiagnosed as generator problems because the symptoms look the same from the outside. The generator won't start, or the power doesn't come on in the house, and the assumption is that something is wrong with the generator. We test the full system rather than assuming.

Transfer switch installation is required for any new generator installation and is also a standalone service for homeowners who have a portable generator and want to connect it to the home's electrical system safely rather than running extension cords. A properly installed transfer switch for a portable generator allows specific circuits in the house to be powered from the generator through the home's wiring without backfeeding the utility line.
