elec sub panel

Question

I am still confused after watching your video on wiring a sub panel. I have a main panel in my house that is supplied by overhead wiring from the utility with 3 wires. My main panel has a common neutral bus and ground bus. I have run 3 wires from the main panel to a sub panel in my pole barn. I have attached the hot wires and run the neutral wire to the common neutral/ground bus in the main house panel. How do I know if my house if properly grounded? How should the sub panel be wired for neutral and ground? How do I know if they are wired properly? Can they be tested?

  1. Watch the video at 2:30 And yes, the neutral and ground are seperated at the sub panel. You’ll have a separate grounding busbar.

  2. I understand your comments except for the pole barn ground. Does the ground rod in the pole barn get separated from the neutral in the sub panel and attached to the sub panel cabinet and a separate ground bus?

  4. You should have the two hots and the natural from the main panel, right? The ground will be coming from a new ground rod installed at the barn.

    You should, must have a ground rod or even two at the house. Just follow the ground from the panel to somewhere close by outside to a grounding rod. Also to the copper pipes in your house.
