I have a little snag in my wiring plans for my detached shop. Here's what I have in place:
I did the load calculations and figured in the distance from the house and worked it out with the wife's uncle, who is a retired lineman. I'd ask him for more help, but he moved to Arizona!
- 100 AMP Square D Home line panel in the shop
- Direct bury rated four conductor cable, 1/0, 1/0, 1/0, 2 awg
- 100 AMP breaker for the panel in the house, Square D QO (200amp)
- The 100 amp QO breaker for the house panel is only rated for 2 awg wire
- The house panel has neutral (white) and ground (bare and green) connected to the same bus bars, along with the bare cable coming in from the pole. There is no bus bar or ground wire anywhere else in this panel.
- The shop panel has a separate bus bar for ground and neutral
- Is there a way to use the 1/0 wire in the breaker rated for 2 awg?
- Do I connect the neutral and the ground to the same bus bar in the house panel, the way everything else is?
- Do I connect neutral and ground bus bars together in the shop panel?
- Should I have a grounding bar (stake) for the shop panel?
