Does it pop the breaker without anything plugged into it? or only when you plug something into the receptacle?
What "breaker" is it popping? the circuit breaker in your CB panel in the house? or the button on the GFCI you installed in the garage?

Have you recently done any nailing in the walls of the garage? Installing shelves, drywall, etc. This could be a problem if you pierced a wire.
with outlet removed does it still trip breaker?and how many wires in the box where gfci in garage is?
how long ago have you moved into the new house? Reason I ask, its a warranty issue, and anytime a breaker is tripping its usually considered a critical issue; builder and electricians like myself don't like it when breakers are tripping for any reason, especially if there is nothing plugged in or there is no load on the circuit. This isn't considered a electrical emergency per se (for example a main breaker tripping would constitute a emergency), but at my shop, if we wired the house, we'd be out the next business day for sure to check it out.
If it trips with nothing plugged in, you most likely have a shorted wire between the breaker box and the receptacle. The breaker is doing exactly what it was designed to do. It is keeping you from burning the building down.
Now would be a perfect time to run some serious wire to the garage and put in a nice 100A panel and move into the modern world.
You say your garage has 1 receptacle? Mine has about 30 receptacles. Which one would you like?
ya it has 1 on the wall and one up top for garage door opener,,,the breaker is in the garage also...or is this something i can do?
...or is this something i can do?
What you *can* do is the grunt work... buying materials, running wires and conduit, mounting boxes for the receptacles and generally getting everything ready. Then have an electrician come in, check your work and make the final hookups.
well its new to me,,,it was built in 2003 and was a foreclosure
You'd be much better off just letting a professional handle it all. I tried working with customers like this a few times early on in my career, and it's nothing but a hassle. Nowadays, I wouldn't even consider it for liability reasons alone. Most times you'll end up paying the guy to undo some of what you've done, negating at least some of the savings.
I agree, I usually charge more if the customer wants to help.

Is the garage door opener on the same circuit? If so, it may be the cause of your problem. If you can't trouble-shoot a blown breaker, you should probably hire an electrician to run electrical. It is something you can do yourself if you have a bit of experience. Good luck!

Odds are pretty good that you have other outlets wired to the GFCI outlet... I'd look at other outlets possibly outside and see if any of them are dead too and may be damaged. I've run into this on newer homes here in Tucson. The single GFCI outlet will have several outside outlets attached to it. ...or one outside will have some inside attached to it. Very annoying!

might test to see what wires are the LINE from the breaker to the GFCI, disconnect those wires and turn the breaker on, if the breaker doesn't trip its a problem with the GFCI wired wrong or something else down stream. If you have the wires (hot, neutral, and ground) from the panel disconnected from the device and the breaker trips, its a dead short in that Romex run. Your looking at allot of busy work to try to troubleshoot this circuit. For the money, I'd call someone with a license and have them fix this issue and kind of give your house (especially since it was a foreclosure) a once over on the electrical system. You'll sleep better knowing your house isn't a electrical house of horrors and a firetrap.
well i just tried to plug something in to the outlet and it does not work...it did not trip the breaker nor the GFCI,,,but the light on the outlet is green...its a new GFCI also...i guess ill get my buddy over to look at it,,,just thought maybe u guys could point me in the right direction.....thanks for ur help
u are correct,,the outlet on my front porh doesnt work nor does the one on the back porch,,i have tried replacing these also but didnt work,,,they put interior outlets outside with no cover
Anyways...if you have interior outlets outside and you don't have at least weatherproof covers over them, then I would say that is where you need to start looking. Chances are the outlets are corroded and/or you may have spiderwebs in there. Bugs love small places to hide and an outlet that is in th eopen is no exception. This alone would cause your GFCI to pop
Does the ground really by-pass the GFCI receptacle like your diagram shows?
sorry about the crappy picture,,,heres a better one,,,
i live in texas by the way
I live in Texas also, howdy. Is the picture you posted accurate? I noticed that you have the line side on the right side of the receptacle . On a GFCI the line side should be on top and any donwstream outlet wires would be on the bottom. Your line side black wire on the right top and the line side white wire on the top left. The wire that is feeding the downstream outlets would be black load wire bottom right and the white load wire bottom left. Your bare groud wires would be tied together with a short pigtail wire connecting to the ground terminal on the GFCI. Have your just recently replaced the GFCI receptacle? Why or when did you start having problems? You said the house was built in 2003?
so ur saying that the bundle wire with 4 wires coming outta of it should be on top,,meaning 1 white on top and 1 black on the opposite side on top and then the set of wires with 2 coming out ,1 white on bottom and 1 black on the bottom ...yes i replaced the GFCI because it didnt work when i moved into the house..thanks dude
The "line" side (top connections) should not have a "bundle" of wires, but just the two that originate from the breaker panel. This is the "power feed' for the receptacle.
The ground wire from that same set of wires should be firmly clamped under the green ground screw on the GFCI. The "bundle of wires" must be the lines to the two additional downstream outlets, with a pair of white wires, a pair of black wires and a pair of ground wires.
You will need to take the two short wires, one white and one black, and connect them to the other two screws on the GFCI, keeping white and black oriented the same as the "line" wires are. Then wire-nut these two short wires to the matching pair of wires from the "bundle". White to white and black to black. The two ground wires from the downstream bundle need to be crimped to the ground wire that goes to the GFCI screw.
You may be right about the bundle of wires and there orientation. He needs to figure out which wires are the line side from the breaker box. I have seen it done several ways. The bundle of wires may not both be from the breaker box. Example one set of wires from breaker box then the other set of wires may go to a light switch or another outlet that they did not want to have GFCI protected. I am not sure what else is not working if it is several outlets they may have went from GFCI receptacle to outlet to another outlet and maybe they did not bring both runs to the GFCI receptacle. I agree he must figure out what wires go where and then he may be able to decide what needs GFCI protection and what does not. Do you think that maybe the GFCI receptacle went bad for what ever reason and when he replaced it he somehow mixed up the wire configuration?
