Short answer: no. This is called backfeeding, and it is one of the most dangerous things a homeowner can do with a generator. This improvised connection bypasses the proper transfer equipment needed to isolate utility and generator power; it can electrocute utility workers and cause fire or equipment damage.
If you are reading this because the power is out and someone suggested the dryer-outlet trick, stop and read the safe alternative below. It costs less than you think.

What Backfeeding Is
A dryer outlet is a 240-volt receptacle wired to your panel. The "trick" involves a homemade double-male extension cord (often called a suicide cord, for reasons that will become clear) connecting the generator to the dryer outlet, pushing power backward through your panel to energize your home's circuits.
It works electrically. That is exactly the problem.
Why It Can Kill Someone
When you backfeed, power does not stop at your panel. It flows backward through your meter and out onto the utility lines, energizing lines that linemen believe are dead. A lineman working on your street during an outage does not expect your house to be feeding thousands of volts back into the grid.
People have died this way. This is not a theoretical risk.
Why It Can Destroy Your Home
A homemade generator-to-receptacle backfeed arrangement can defeat important protections and introduce serious hazards:
- No proper overcurrent protection on the generator feed
- The homemade cord itself is unlisted, unprotected, and a fire starter
- If utility power returns while you are backfeeding, the collision can destroy your generator, your panel, and start a fire
- Insurance coverage for damage depends on the policy terms, facts and applicable exclusions; do not assume a claim will be covered
Is It Actually Illegal?
An improvised male-to-male cord and dryer-receptacle hookup is not an approved premises-wiring connection. Safe generator connections require suitable listed transfer equipment and installation consistent with adopted electrical codes and local requirements.
The Safe, Legal Alternative
A generator interlock kit, installed by a licensed electrician with a permit:
- When correctly installed and operated, prevents the two intended breakers from being closed simultaneously
- Uses a proper outdoor inlet box instead of a dryer outlet
- Costs a fraction of a standby generator (see our cost breakdown on what an interlock installation costs)
- Is installed in a single visit, usually a half day
This is the correct way to do what the dryer-outlet trick tries to do. For the full overview, see our generator interlock installation page, or our guide on safe ways to connect a portable generator.
What to Do If You Already Did It
No judgment. If the power is out and you already ran a cord to the dryer outlet:
- Turn off the generator and disconnect the cord now.
- Do not do it again.
- Call a licensed electrician about an interlock kit before the next storm.
And if you suspect any damage, burning smell, or scorched outlets, call an electrician immediately. A thorough electrical safety inspection can confirm whether any wiring was harmed.
Frequently Asked Questions
Here are the questions Florida homeowners ask most often about backfeeding a generator through a dryer outlet.
What is a suicide cord?
A homemade double-male extension cord used to backfeed a generator through an outlet. Both ends have exposed live prongs. The name is descriptive.
Can backfeeding really kill a lineman?
Yes. Backfed power energizes utility lines that crews believe are dead. This has caused lineman fatalities during storm restoration.
Will my insurance cover damage from backfeeding?
Coverage cannot be predicted without reviewing the exact policy and circumstances. Unapproved electrical work can create both serious safety risks and coverage disputes.
How much does the safe alternative cost?
Ask for a written estimate for a listed interlock or transfer switch appropriate to your panel. Far less than a fire, a lawsuit, or a standby generator.
I only need to power a few things. Is there a simpler safe option?
Yes. Run properly rated extension cords directly from the generator (parked outdoors, 20+ feet from the house) to individual appliances. Follow the generator and cord manufacturers' instructions, use outdoor-rated cords with suitable capacity, and keep the generator outside at least 20 feet from buildings with exhaust aimed away. What is not safe is connecting the generator to your home's wiring without a transfer device.
