Help...
I have a double breaker labelled as 50 amps that runs from my house to my garage by two 6 gauge stranded wires. It goes to a box in the garage that has 4 15 amp breakers in it, 2 on each leg. Each of the 6 gauge wires connect to each leg in the box. I have a grounding rod 6 feet in the ground as that is a far as it will go, must be rock below it, and the rod is connected to the neutral / common strip in the box.
Is this setup correct? I can measure 125V on each leg to ground, but once I put a load on one of the legs, the voltage drops to 70V and the other leg reads 180V, what is going on here?
Thanks much,
Sean
