A inspector told an electrician he couldn't run a insulated copper conductor to a ground rod. He made him change it to a bare wire.
That doesn't seem right to me especially when he referenced 250.64(A).
 
He needs a refresher course in electrical inspection. It can be insulated or bare, stranded or solid. I've heard guys say that it has to be solid which is also false. We use #6 stranded green if we have it or any other color that's laying around.
 
In my view this is one of those situations where the electrician should fight back and refuse to do it. I know this is not everyone's cup of tea to do so but things like this not challenged just perpetuate incompetency and lead to more "urban legend" code.
 
That's what I thought, some electricians will do what the inspector says without questioning him.
I feel the inspectors need to be held accountable for some of there calls. Thank you.
 
The inspector needed to back up to article section 250.62

250.62 Grounding Electrode Conductor Material. The
grounding electrode conductor shall be of copper, aluminum,
or copper-clad aluminum. The material selected shall
be resistant to any corrosive condition existing at the installation
or shall be protected against corrosion. The conductor
shall be solid or stranded, insulated, covered, or bare.

Obviously you need a bare copper if you use #4 as a cee but not to the ground rod. The inspector needs to actually think about it for a second.... I always use bare copper but not because insulated isn't allowed...

Yeah I mean really what negative effect could using an insulated conductor have? :rolleyes:
 
Unless it was insulated AT the ground rod under the clamp... Would hope even the most junior electrician would not make that mistake.
 
This is clearly a case of "I want to see it done the way I've always seen it done!" syndrome.
