garage wiring

[toomany]

I am building a new garage. The electric wiring is done. There are two white, two black and three green wires in each j box (total of 6).
How should I connect the receptacles?

All the receptacles in any garage must be GFI protected. Normally this is done by installing a GFI style receptacle in the first receptacle on each branch circuit serving garage receptacles. YOu must wire the black and white of power entering that first receptacle box to the line side to the GFI receptacle. Then the black and white wires going to the next receptacles must be connected to the load side of that same GFI receptacle. This way all load is passing through that GFI receptacle placed as the first receptacle on that branch circuit.

Then all other receptacles are normal duplex receptacles connecting the black to the brass screw and white to the silve screws and bare to the green screw after you have wire nutted the bares together with a pigtail going to the receptacle you must only install one bare wire to that green screw designed only for one wire.

Good Luck
