Connecting a Generator, at a Glance
A generator only helps once its power reaches your house — and there are exactly three honest ways to make that happen: extension cords for a few essentials, or an interlock kit or transfer switch for your whole panel, both installed by a licensed electrician. This guide walks through all three, how to decide, and the dangerous 'suicide cord' shortcut to never try. There's a printable 29-page version up top.
Common Questions
1 What are the three safe ways to connect a generator to my house?
Outdoor-rated extension cords to individual appliances, an interlock kit at your panel, or a transfer switch at your panel. The last two both need a licensed electrician and usually a permit.
2 What is a 'suicide cord' and why is it so dangerous?
A cord with a plug on both ends, pushed into an outlet like a dryer plug to 'backfeed' the house. It can send deadly voltage out onto the utility lines — risking a lineman's life — bypasses your home's protection, and is illegal. Never use one.
3 Can I power my furnace or well pump with extension cords?
No. Those are hardwired 240-volt loads with no plug to begin with. They need an interlock kit or transfer switch installed at your panel by a licensed electrician.
4 What's the difference between an interlock kit and a transfer switch?
Both safely feed your panel from a generator. An interlock kit is a simpler, more affordable sliding plate where you manage breakers yourself; a transfer switch adds dedicated, labeled switches for a cleaner, more automatic feel. See our deep-dive guides on each.
5 Do I need a permit to install one?
In most areas, yes — any work that adds a breaker or changes your panel typically needs a permit and inspection. Your electrician will know your local requirements.
6 How do I decide which one is right for my home?
Start with your must-run list. All plug-in items usually means cords are enough. A furnace, a well pump, or whole circuits means an interlock kit or transfer switch — then it comes down to budget versus how polished you want the setup to feel.
