Re: Garage Door Openers

I always just put the garage door opener on the lighting circuit in the garage. I've never seen one that pulled enough amps to require its own circuit.
 
Re: Garage Door Openers

I installed two GDOs on a 15A lighting circuit after checking with the mfg web site. If I remember correctly the openers draw less than 3 amps.
 
Re: Garage Door Openers

I usually bring a feeder to the garage door outlets and then jump down to the regular garage outlets which will be ground faulted. This way you have a 20 amp circuit feeding the garage and the ground fault is AFTER the door openers. Lighting can then be put on with other lights.

Nowhere. The NEC doesn't have such a rule. What makes you suspect that there is an NEC rule about this?

Re: Garage Door Openers

Your inspector may require a dedicated single receptacle rather than a duplex if it's not on with the GFI. I don't see where a dedicated circuit is needed.
 
Re: Garage Door Openers

I see nothing in either of the 4 articles cited that would require a 20A dedicated circuit. :confused:
 
Re: Garage Door Openers

I don't think its a bad idea but its not required unless that thing takes 50% of the circuit.And thats not likely.It is a handy place to tap for addons.Only way you could inforce this is if the mfg. requires it.

Single receptacle might keep owner from from?plugging in his drill etc into a non GFCI.
 
Re: Garage Door Openers

A garage door opener receptacle is generally not readily accessible unless the garage has a low ceiling. Therefore no gfci protection would be necessary, nor would you need a single receptacle.

if someone is going to get a ladder to plug their drill into this receptacle to avoid a GFCI, more power to them. they would also drag an extension cord into the house to acheive this if the garage door opener receptacle was not there. We can not protect idiots.

As Scott says, 210.8(2)Exception No. 1 to (2): would be the applicable section in this case

210.8 Ground-Fault Circuit-Interrupter Protection for Personnel

(2)Garages, and also accessory buildings that have a floor located at or below grade level not intended as habitable rooms and limited to storage areas, work areas, and areas of similar use

Exception No. 1 to (2): Receptacles that are not readily accessible.

Re: Garage Door Openers

I don't get it? If dishwashers, disposals and jacuzzi's have to have their own circuit why shouldn't garage door openers? It is in fact a motor and/or a fixed appliance. Whether it is a 15amp or 20amp, it is still a motor load situation and should have its own circuit!

The NEC does not directly require any of those items to have dedicated circuit.

Must it have its own circuit? No, not by any NEC requirement. Should it have its own circuit? That is a design choice. For a dishwasher, and maybe for a disposal, a separate circuit would probably be a good idea. For a garage door opener, I think a separate circuit would be a waste of a breaker and a waste of wire. It is not a bad thing, if the owner wants to pay for it.
 
Re: Garage Door Openers

I once connected a disposal and dishwasher to the same 15 amp circuit. I know the "Always exceed the NEC" crowd is having a heart attack right now but I did it and if felt great! :p

Was it at your own home? If so, did it give you a large number of nuissance trips? If it was not your own home, did you go back and inquire of the owner whether it give him or her a large number of nuissance trips? :D
