Hi all
I am finishing my JD Shed/barn and I am in the electrical wiring phase of the project. I have an existing underground in conduit 8 gage wire that runs from the main service panel to a sub panel located in the JD Shed/barn. This wire is about 150 feet long and is fused at 30 amps. It supplies 120 volts only.
Question. I've been told the sub panel should have the neutral and ground wires held separate, and there should be a grounding rod close to the metal building. Is only the building grounded to this grounding rod, or is the bare ground electrical wire also attached to the grounding rod? Reason I ask, is the original electrician who wired this existing service supply hooked the neutral and ground wires together at the outlet post, and also connected them to the grounding rod. (existing supply was for a 30 amp service to my motor coach)
