elec sub panelReport
Please briefly explain why you feel this question should be reported.
I am still confused after watching your video on wiring a subpanel. 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 subpanel 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?
