The Real Dangers of Backfeeding a Generator
Last verified: September 2026
Why backfeeding through an outlet can kill — a utility worker, your family, or you — and the safe, legal way to do the very thing it's tempting you to shortcut. Questions? My number is (330) 200-8042.
Why Backfeeding Is So Dangerous
Backfeeding — pushing generator power into your house through a regular outlet — is the most dangerous mistake people make with a generator. It can electrocute a utility worker, start a fire, shock your family, and destroy your generator. It's also against code and often illegal. This guide explains the dangers plainly and the safe, legal alternatives. There's a printable 29-page version up top.
Common Questions
1 What is backfeeding?
It's forcing generator power into your home through an outlet instead of a proper transfer switch — often with a dangerous double-ended 'suicide cord.' It sends power backward through your wiring and can reach the street.
2 Why can backfeeding kill a utility worker?
Your generator's power can flow back out to the lines and be stepped up to high voltage by the transformer. A lineman working on a wire they believe is dead can be electrocuted. A transfer switch prevents this by design (NEC 702.5).
3 Isn't it safe if I turn off my main breaker?
No. It relies on a person remembering perfectly every time, doesn't fix the live prongs on the cord, and is still against code. Proper transfer equipment builds the safety into the hardware.
4 Is backfeeding illegal?
Connecting a generator without proper transfer equipment violates the electrical code and is illegal in most places. It can also cause problems with insurance if it leads to damage.
5 What should I do instead?
Use a transfer switch or an interlock kit (both installed by a licensed electrician), or run outdoor-rated cords to individual appliances. All three are safe and legal.
6 I've been backfeeding — what now?
Stop now, safely store any double-ended cord, and call a licensed electrician about a transfer switch or interlock. No judgment — just switch to the safe way. Bill can help you plan it.
