As of mid-September 2026, here in Port St. Lucie, the double-ended cord is the shortcut that comes up whenever the power goes out: plug the portable generator into the dryer outlet and light up the whole house at once, instead of running extension cords room to room. It looks like a harmless stand-in for a proper transfer switch. The generator is out back, the dryer outlet is right there, and a plug is a plug.
That is northern house logic, and it does not work here. FPL’s own generator safety page is blunt about feeding generator power into the house wiring: “Do not wire your generator directly to your breaker or fuse box, because the power you generate may flow back into power lines and cause severe injuries, or even kill a neighbor or utility crew working to restore power.” The city’s after-the-storm guidance says the same thing more quietly: connecting a portable generator to home wiring can cause safety hazards.

What OSHA says
The federal workplace safety agency is just as direct: “Never attach a generator directly to the electrical system of a structure (home, office, trailer, etc.) unless a qualified electrician has properly installed the generator with a transfer switch.” OSHA says attaching a generator directly to a building’s electrical system without a properly installed transfer switch can energize wiring systems for great distances, which creates a risk of electrocution for utility workers and others in the area.
Why the dryer outlet isn’t a shortcut
A transfer switch is the piece that keeps the generator’s power where it belongs. FPL says the generator should be connected to the house wiring using a transfer switch, to prevent it from backfeeding utility lines and causing possible damage to the generator when utility power is restored. The Building America Solution Center says all home power generation requires strict disconnect controls to isolate the home system from the grid to ensure the safety of utility workers. A cord into the dryer outlet has none of that…
