Running a portable generator with extension cords works in a pinch, but it is not a safe or practical long-term solution. A properly wired generator hookup with a transfer switch lets you power circuits throughout your home safely, disconnects your home from the grid during operation, and protects utility workers from back-fed power. WireNut installs both manual transfer switches for portable generators and automatic transfer switches for standby units in Centennial homes.

Generator installation is a panel-level electrical project. Our electrical panels team handles any panel work needed before the transfer switch installation. For whole-home backup power planning that includes new circuits, our electrical installation team coordinates the scope. See all Centennial electrical services.

Here are the generator-related projects our Centennial electricians handle most often.

Why Do I Need a Transfer Switch for My Generator in Centennial?

A transfer switch disconnects your home from the utility grid when your generator is running. Without one, your generator can push power back through your meter and onto the utility lines, which creates a serious electrocution risk for utility workers who are working on those lines during an outage. It also puts your generator and appliances at risk when utility power is restored suddenly without the disconnection. In Colorado, connecting a generator to your home’s wiring without a proper transfer switch is against code.

A transfer switch also makes using a generator far more practical. Instead of running extension cords to individual appliances, you can power selected circuits in your home directly, including sump pumps, refrigerators, lighting, and HVAC equipment, through your existing outlets and switches. WireNut installs manual and automatic transfer switches for Centennial homes of all sizes.

What Is the Difference Between a Standby and a Portable Generator Setup?

A standby generator is permanently installed outside the home, connected to a natural gas or propane fuel supply, and wired with an automatic transfer switch that starts the generator and switches the home to generator power within seconds of a utility outage. Standby systems require no action from the homeowner and can run indefinitely on the fuel supply. They require a permit and professional installation.

A portable generator is stored and brought out when needed, connected to the home through a manual transfer switch or generator outlet, and requires manual starting and fueling. Portable setups are less expensive upfront but require more involvement from the homeowner during an outage. Both approaches are valid depending on your backup power goals and budget. WireNut can install transfer switches for either type in Centennial.
