Separation of Neutral and Ground Wires in Sub Panels
[ad#block]Electrical Question: We are considering buying a manufactured cabin that has a Jacuzzi tub. The neutrals and grounds are tied together on the same bus in the sub panel. One home inspector said they need to be separated, the other said they are fine since they are both insulated and are grounded at the main panel. Which is correct?
This electrical question came from: Dan, from Big Bear City, California.
