This is Turtle.
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
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
