I would like to know about the wiring being run from a main switch box to a smaller subpanel and to the ground or neutral wire you use. If you had a 200 main switch box and wanted a 100 amp subpanel installed up stairs. What type wire would you have to run to get the configuration right. Now wire size has nothing in my question here. Here is the three choices to pick from.
1) Run #2/ 3 wire and use third wire / white as ground and netrual !
2) Run #2 / 2 wire with naked ground. Use the naked ground as netrual and ground wire.
3) Run #2 / 3 wire with naked ground. Use the naked gound and the insulated white wire as ground and netrual.
I will always use the #2 / 3 wire with insulted ground but what about the #2 / 2 wire with a naked ground. Can the naked ground be used as netrual and ground suppling this subpanel or used in this application in residentiual or other in anyway. It might sound a little stupid but I got to know if there is any exception for this to be used?
I'm just checking up on a electrician around here that is doing it outside the city where there is no inspection of wire or wire codes. I just did not think you could do it but hey there maybe some exceptions somewhere I don't know about.
