Insulated Grounded Conductor

[mikesimpson5]

Help!!!!!!!!!!!! I need to find where in the code it specifically says that the grounded conductor is to be insulated after the main service disconnect. I know I have found it before, but this time it is eluding me.:?

start with art 200

I don't think that you will find a rule that specifically states that. The closest would be 250.24(A)(5).

Also 230.41 indirectly answers this. As far as I know there is no statement that allows a grounded conductor to be uninsulated except for services.

 

[Dennis Alwon]

250.118 also permits the egc to be bare but not the grounded conductor. If the grounded conductor was bare how would you keep it isolated from the egc past the service disconnect as stated by Don in 250.24(A)(5)

250.140 allows an uninsulated grounded conductor in a SE cable ran from a main panel to bond frames of a dryer or range for an existing installation.

True but you cannot install that as a new circuit
