About Reliance Controls
A specialist brand for portable generator connections.
- Based inRacine, Wisconsin
- Known forManual transfer switches
- Also makesPower inlet boxes and generator cords
- Works withMost portable generators
Reliance Controls focuses on one job: connecting portable generators to homes safely. Its pre-wired manual transfer switches mount next to your main panel and let you switch chosen circuits from utility power to generator power.
Many Reliance switches include wattmeters that show how much power each side of the generator is supplying, so you can balance loads and avoid overloading your generator.
The Parts of a Reliance Generator Hookup
Four simple parts turn a portable generator into a safe home backup system.
| Part | What it does | Where it goes |
|---|---|---|
| Manual transfer switch | Moves selected circuits between utility and generator power | Beside your main panel |
| Power inlet box | Weatherproof plug-in point for the generator cord | Outside wall, near where the generator will sit |
| Generator cord | Connects generator to the inlet box | Stored with the generator |
| Wiring between them | Carries power from the inlet to the switch | Run through the basement, garage or wall |

Matching your generator
We match the inlet box and cord to the twist-lock outlet on your generator, usually 30 amps for mid-size units and 50 amps for larger ones. Popular portables like Champion and Generac models connect easily.
Keep power off the street
A listed transfer switch makes it impossible for generator power to flow back onto JCP&L lines, protecting line workers fixing your street.
Choosing Which Circuits to Back Up
The right circuit plan is what makes an outage livable.
Most Reliance switches handle a set number of circuits, often 6 to 10. We help you pick the ones that matter most during an outage in your home:
- Furnace or boiler
- Refrigerator and freezer
- Sump pump or well pump
- Key lights and outlets
- Internet and phone charging
- Garage door opener
Stay within your generator's limits
Every generator has a running wattage limit. We add up the loads you choose and make sure they fit, with room for things like a well pump or fridge compressor to start. The switch's wattmeters help you keep it balanced during an outage.
