Portable Generator Hookup — Frequently Asked Questions

Why can't I just plug my generator into a wall outlet?

Never do this — it's called backfeeding and it's illegal and deadly. Without a proper transfer switch or interlock, power flows backward through your home's wiring onto the utility lines, which can electrocute Eversource line workers restoring power during an outage. It also bypasses your circuit breakers, creating a severe fire risk inside your home.

What's the difference between a manual transfer switch and an interlock kit?

An interlock kit is a mechanical device installed on your main panel that prevents the main breaker and generator breaker from being on simultaneously. It costs less and works with most panels. A manual transfer switch is a separate sub-panel with designated circuits that switch between utility and generator power. We'll recommend the best option for your setup during the estimate.

Can I install a generator hookup with any portable generator?

Yes. We install standard 30A and 50A NEMA inlets that work with virtually all portable generators. We'll need to know your generator's wattage and outlet type to ensure the inlet and wiring are properly sized for your Connecticut home.

What size generator do I need to run my house?

It depends on what you want to power. A 5,000-7,500 watt generator can typically run a fridge, lights, router, and a gas furnace. A 10,000+ watt generator can handle more, including a well pump. We perform a load calculation to help you choose the right size.

How long does a portable generator hookup installation take?

Most portable generator inlet and interlock kit installations take about half a day (3-5 hours). We handle the complete setup including the outdoor inlet, wiring to the panel, and interlock installation, testing everything before we leave.

Do I need a permit for a portable generator hookup in New Canaan?

Yes. Any hardwired electrical connection to your home's electrical system requires a permit and inspection by the local building department to ensure strict compliance with NEC safety codes. We pull all necessary permits for you.
