A transfer switch is what makes your generator safe and legal to use. Without one, you’re either running extension cords through windows—which limits what you can power and creates tripping hazards—or you’re risking a dangerous backfeed into utility lines that can electrocute power crews and damage equipment.
At Superpower Electric, we install both automatic transfer switches for our complete whole-house standby generators installation service and manual transfer switches for homeowners who want a safer way to connect portable generators. Every installation meets NEC code requirements and passes local inspection.
An automatic transfer switch continuously monitors your utility power. The moment it detects an outage, it signals your standby generator to start and transfers your home's electrical load from the utility to the generator—all within seconds, with no action required from you.
When utility power returns, the ATS reverses the process: it transfers your load back to the grid and signals the generator to begin its cooldown cycle before shutting off.
We install Generac, Cummins, and other premium ATS units matched to your generator and home's electrical system. Proper sizing is critical—an undersized transfer switch creates a bottleneck that limits how much power your generator can deliver.
Key benefits of automatic transfer switches:
If you have a portable generator and want a safer, more convenient way to use it, a manual transfer switch is the answer. Instead of running extension cords, you connect your generator to a dedicated inlet box on the outside of your home. Then you manually flip the transfer switch to move selected circuits from utility power to generator power.
Manual transfer switches are code-compliant and eliminate the backfeed risk that comes with plugging a generator directly into an outlet (which is illegal and dangerous). They also let you power hardwired systems like your furnace, well pump, and sump pump that you couldn't otherwise reach with extension cords.
Backfeeding—when generator power flows backward into utility lines—kills people. Line workers assume downed wires are de-energized after the utility cuts power. When someone’s improperly connected generator sends electricity back into those lines, workers can be electrocuted.
Beyond the safety issue, backfeeding damages your generator, can fry sensitive electronics in your home, and violates electrical code. If a fire or injury results, you’re liable.
Every transfer switch we install includes proper interlocking mechanisms that make it physically impossible to connect your generator and utility power simultaneously. This isn’t optional—it’s how the system must work to protect everyone.
Already have a transfer switch that’s acting up? Older units can develop issues with contacts wearing out, causing erratic switching or failure to transfer at all. We diagnose and repair transfer switch problems or replace outdated units with modern, more reliable equipment.
If you installed a smaller generator years ago and have since upgraded, your original transfer switch may be undersized for your new unit. We can upgrade your transfer switch to handle the additional capacity.
