I have a GFCI receptacle in the garage. There are two regular outlets in the garage as well that I believe are "downstream"/protected by this outlet as required by code. There is also another regular outlet on the circuit that is inside in the closet (on wall between closet and garage). I plugged a tester into one of the regular outlets in the garage and accidentally hit the button to throw a fault. GFCI outlet tripped and will not reset. At this point, the outlet in the house appears to still work but the ones in the garage do not.
In the box for the GFCI receptacle, there are 3 cables coming into the box. There is one coming from the top and two from the bottom. I tried replacing the GFCI receptacle and thought I took care to put the wires in the same location, but now nothing works! The inside outlet no longer works so now I'm trying to figure out the correct way to wire the GFCI outlet.
I have been looking for a wiring diagram for GFCI when there are 3 cables but haven't found any. Is one cable the from the service panel and the other two load cables with one going to the inside outlet and the other going to the next outlet in the garage? (I would think the panel cable would be the one coming in from the top of the outlet box). But that isn't how it was wired. Worse, now the inside outlet isn't working either!
This is how it was wired (and I believe is the way I wired the new GFCI receptacle)
Top cable: black wire goes to GFCI Line (position 1) white wire goes to GFCI Line (position 2) Bottom Right cable: black wire goes to GFCI Line (position 2) white wire goes to GFCI Load Bottom Left cable: black wire goes to GFCI GFCI Load white wire goes to GFCI Line (position 1)
I'm really confused. Since the inside outlet initially continued to work, I would think that it would be first in circuit directly from service panel. Then its load wire would come into the GFCI outlet as its line cable and there would be one load cable to the next outlet and then that outlet would feed the last outlet on the circuit. So why the 3 cables?
