I am adding a branch circuit box to a storage room. This box will supply power for a 220v welder and a small 220 4K watt heater. I have noticed that all the 110v wireing is in 1/2" conduit from the celing down.
Is this required by most codes, and what about "overhead runs"?
Also, since this box will be mounted in a joining separate room with main breaker panel, what are the grounding rules--since there is no main breaker and no way to bond the ground on the new box?
