Grounding Electrode Conductor

[timm333]

I am trying to figure out what would be the insulation level of the grounding electrode conductor (GEC), which connects the neutral point of transformer to ground, in a solidly grounded system. NEC 250.62 says that GEC can be bare or insulted; but it does not tell that when insulated then how much would be the minimum voltage level of the insulation. I think an insulation of 600V for GEC would be Ok for both LV and HV systems, but just need to confirm.

NEC 250.184(A)(1) says that the minimum insulation level of “neutral” shall be 600V. Is there any similar section in NEC which says that what would be the minimum insulation level of “GEC”? Thanks

There is no insulation required so there is no minimum insulation level. The requirement is the proper AWG size.

There is no minimum level of insulation required on a conductor that requires no insulation. Why would there be?

I don't understand the problem. Bare would indicate NO insulation value.

Three of three in a heartbeat.

I don't know of any section that gives us an answer to your question. I can't see why it would matter as current is generally not on the grounding electrode conductor.

Ok thanks. That clarifies it.

It could be as thin as a coat of paint.
