I have properly buried a 12-3 with ground flat cable (UV resistant – made to be buried) to a storage barn. I am running two – 20 amp circuits using this cable. When I come up out of the ground, I am separating into 2 GFI outlets each a separate circuit. I am using red and black as my hot wires. I am using the white as the neutral for the red. My question is this: Can I use the bare copper for the neutral for the black **AND** as the ground for both circuits? What is proper wiring for wiring and grounding both GFI outlets?

Hi, Welcome to Just Answer. My name is XXXXX XXX would be glad to assist.
You need to purchase a double pole 20 amp GFCI breaker for your installation,
1. You CANNOT use a ground wire for neutral, it is illegal and dangerous.
2. You need a double pole GFCI breaker, for your particular panle
You can use the 2 GFCI receptacles, you must be sure that the white is pigtailed to 2 wires and the power has to go into the LINE side of the GFCI
I guess you will have a junction box before the receptacles so you can split the circuits?
In that junction box, you connect 2 white wires to the one in the 12/3, then you have 2 neutrals
Do the same for the grounds
Then connect all incoming power to the GFCI LINE terminals

You are quite welcome.You are supposed to use a double pole breaker when making the shared neutral.Both breakers are supposed to open at the same time on a shared neutral circuit.That is why I was suggesting the double pole GFCI breaker, to kill 2 birds with 1 stone so to speak.So, if you use the GFCI receptacles, still use a standard double pole breaker. The 2 circuits have to be opposite phases, not the same phase.41057.7070957176
