No, it is not safe to plug a generator into a house through a wall outlet or dryer receptacle. The only safe way to connect a generator to your home's wiring is through a transfer switch or a code-approved panel interlock installed by a licensed electrician. Plugging in directly, often called "backfeeding," can send power back onto utility lines and injure line workers. It can also damage your generator and start a fire. During Santa Ana wind season, when Southern California Edison may shut off power to reduce wildfire risk, this question comes up in almost every Antelope Valley household.

What is backfeeding, and why is it dangerous?
Backfeeding means pushing generator power into your house wiring through an outlet using a double-male "suicide cord." Without a transfer switch, nothing stops that power from flowing out of your panel and onto the utility lines. Your neighborhood transformer can step that voltage up to thousands of volts on the line, putting the crews working to restore power at real risk. Backfeeding is also dangerous for the people inside the house: the exposed prongs on the cord are live.
What's the difference between a transfer switch and an interlock?
- Transfer switch: A separate switch wired to selected circuits. It physically disconnects those circuits from the utility before connecting them to the generator. Automatic transfer switches pair with standby generators and switch over on their own.
- Interlock kit: A mechanical plate on your main panel that makes it impossible to turn on the generator breaker while the main breaker is on. It works with a portable generator and a dedicated inlet box outside.
Both keep utility power and generator power separated. Which one fits depends on your panel, your generator and which circuits you want to run. Our generator installation service covers both.
Why does this matter more in the Antelope Valley?
Santa Ana winds typically run from fall through early spring, and SCE uses Public Safety Power Shutoffs (PSPS) in high-fire-risk areas like Acton, Agua Dulce and parts of Palmdale. An outage can last hours or days. High desert winter nights also drop near freezing, with Palmdale lows averaging the low 30s°F in December and January. A home that loses power can lose heat, well pumps and refrigeration all at once. For more on outage planning, read our guide to generator installation for outages and PSPS events.
What does a safe generator hookup involve?
- Size the generator to the circuits you actually need (well pump, fridge, furnace blower, lights).
- Install a transfer switch or interlock plus an outdoor inlet box.
- Pull the permit and pass inspection.
- Run the generator outdoors, well away from doors and windows, to avoid carbon monoxide.

Frequently Asked Questions
Can I just run extension cords from my generator instead?
Yes. Running heavy-duty extension cords from the generator directly to individual appliances is safe as long as the cords are rated for the load. It's inconvenient, and it can't power hardwired items like a furnace or well pump. That's where a transfer switch or interlock helps.
Do I need a permit for a generator interlock or transfer switch?
In most Antelope Valley jurisdictions, yes. It's panel work and has to be inspected. A licensed electrician handles the permit.
Will a portable generator run my whole house?
Usually not. Most portable units are sized for essential circuits. A whole-home standby generator needs a larger unit and an automatic transfer switch.
