Garage door circuit breaker details.

Here are a few reasons your garage door opener might trip your circuit breaker along with suggestions to fix the problem. A lighted garage door opener may not be used to satisfy this requirement even if the light is controlled by its own switch. I think the rate is increasing. If you find that other lights or electrical circuits in the garage aren t operating this is the likely cause and you ll need to reset the breaker or gfci or replace the burned out fuse.

A few weeks ago the breaker that my garage door opener and motion light are connected to tripped. 2008 nec the not readily accessible exception removed from the code so ceiling receptacles now required to be gfci protected. The wiring in my garage is on the fritz. I reset it and the breaker was fine for a few weeks.

Try connecting other devices to other power outlets on the same circuit. When installing a 240 volt circuit attach the black and red wires into the slots under the screws on the breaker. You could have a weak circuit breaker or a bad gcfi electrical outlet. A short in the control board or the wiring of the garage door opener could also cause that problem.

Here are the details. A short in one of the light sockets could also cause that problem. If your opener has a 200 watt lighting system for example the lights alone will draw just under 2 amps. If the circuit breaker or gfci is tripping repeatedly it s a sign that there is a short circuit somewhere in the system possibly even the garage door opener itself.

I removed the 100w lightbulb but the trips. The breaker tripped again and wouldn t reset. I ve replaced the drive gears once but otherwise it s been quite reliable. I replaced the breaker its a qo 20a thinking it was bad but it kept tripping.

It s nominally 1 3 hp. If you have a 3 car garage with three openers you may want to consider a 20 amp circuit breaker. But there was an exception for receptacles that are not readily accessible which is defined as above 6 8 above floor such as a ceiling garage door opener receptacle. For 120 volt circuits attach the black wire to the breaker and snap it to the power bus.

You can unplug the garage door opener. Recently it has started blowing its breaker intermittently. If the problem persists ask an electrician to check the breaker. Exterior lighting detached garages with electricity must have a light outside each grade level egress door and this light must be controlled by a wall switch or motion sensor.

The white and bare wires will be attached under the screws on the neutral bus.
