Watch it work
Real fire. Real breaker box. Nobody touching it.
The second the heat hits 340°F, Panel Guard sprays by itself and knocks the fire down inside the box.

The problem
It starts behind a closed metal door.
A loose wire or a worn breaker can heat up inside your panel for hours. Out of sight, in a basement, a garage or a closet. By the time you smell it, it is no longer a small fire.
It happens when no one is watching
At night while your family sleeps, or during the day while everyone is at work and school.
You can't see it coming
The panel door is closed. The first sign is often a strange smell that's easy to shrug off.
A smoke alarm only warns you
It can wake you up. It can't put anything out. An extinguisher only works if someone is home, awake and holding it.
Where fires start
One home. Five fire risks.
Tap a number to see why each spot needs protection.
Breaker panel
Where most home electrical fires start
Loose connections, worn breakers and overloaded circuits can heat up for hours behind a closed steel door. Out of sight, and out of reach of your smoke alarm.
Laundry & dryer
Lint, heat and a running motor
Dryers run hot for an hour at a time, often while you're out or asleep. Lint builds up where you can't see it.
Garage & e-bike
Batteries charging all night
E-bikes, scooters, power tools and battery packs charge in the garage overnight, right next to the door into your home.
Your car
You can't fight an engine fire while driving
Wiring and fuel lines under the hood get hot every day. If something sparks, you have seconds to pull over.
TV & office
The power strip nobody looks at
Chargers, routers, TVs and consoles plugged into one strip behind the furniture, running 24/7.

FAQ
Questions? We've got answers.
Still unsure? Email us and a real person will reply within 24 hours.
Where do I put it?
Inside your main breaker box. Open the panel door, peel off the 3M backing and press it onto the inside wall or inside the door. It also works in a sub-panel, behind the dryer, in a battery or e-bike charging cabinet, in a media cabinet or under the car hood.
Do I need an electrician?
No. There's no wiring and nothing to connect. If you can open your breaker box door, you can install it in about 30 seconds. Never remove the inner cover of your panel.
Is it safe for my wiring and breakers?
Yes. It uses a low-corrosion aerosol made for electrical equipment. It is designed to put the fire out without damaging the wiring around it.
Can it go off by accident?
It only activates when the heat around it reaches about 340°F. Normal room, attic or garage temperatures (from -58°F up to 194°F) will not set it off.
Does it replace my smoke alarm or fire extinguisher?
No. Keep them. Panel Guard adds the one thing they can't do: put out a fire inside the box automatically, even when nobody is home or everyone is asleep.
How long does it last?
Up to 10 years with no maintenance, no batteries and no refills. Once it has activated, replace it with a new one.
How many do I need?
One per enclosed space. Most families start with three: the main breaker box, behind the dryer and the garage or car.
How fast is shipping?
Orders ship within 1–2 business days and usually arrive within 8–12 business days. Shipping is free on 2 or more units. You'll get a tracking link by email.
What if I'm not happy with it?
You're covered by our 30-day money-back guarantee. Email us within 30 days of delivery and we'll refund you in full.
Don't wait for the smell of smoke
Protect your home tonight.
It takes 30 seconds to install and it stands guard for up to 10 years. Most families protect the breaker box, the dryer and the garage.
