Garage door circuit breaker details.

A lighted garage door opener may not be used to satisfy this requirement even if the light is controlled by its own switch. The white and bare wires will be attached under the screws on the neutral bus. 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. A short in the control board or the wiring of the garage door opener could also cause that problem.

A bad drive motor could cause the circuit breaker to trip. Here are the details. The breaker tripped again and wouldn t reset. Most modern garage door openers draw from 3 to 5 amps depending on what type of lighting your opener has.

Try connecting other devices to other power outlets on the same circuit. 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. I removed the 100w lightbulb but the trips. It s also possible that the circuit breaker fuse or gfci outlet powering the door opener circuit has tripped or burned out.

You can unplug the garage door opener. The wiring in my garage is on the fritz. For 120 volt circuits attach the black wire to the breaker and snap it to the power bus. Recently it has started blowing its breaker intermittently.

I reset it and the breaker was fine for a few weeks. A short in one of the light sockets could also cause that problem. A few weeks ago the breaker that my garage door opener and motion light are connected to tripped. It s nominally 1 3 hp.

Here are a few reasons your garage door opener might trip your circuit breaker along with suggestions to fix the problem. 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. If you have a 3 car garage with three openers you may want to consider a 20 amp circuit breaker. I ve replaced the drive gears once but otherwise it s been quite reliable.

My liftmaster garage door opener is 27 years old. I replaced the breaker its a qo 20a thinking it was bad but it kept tripping. You could have a weak circuit breaker or a bad gcfi electrical outlet. 2008 nec the not readily accessible exception removed from the code so ceiling receptacles now required to be gfci protected.

If the problem persists ask an electrician to check the breaker.
