Subject - Bare or Insulated
David Hyatt Does the code specify grounds in a raceway or otherwise of a certain size to be insulated or can they be bare?
David Hyatt That would make sense, if it is isolated to be insulated.
JimmyDee This should answer.
250.118 Types of Equipment Grounding Conductors.
The equipment grounding conductor run with or enclosing the circuit conductors shall be one or more or a combination of the following:
(1) A copper, aluminum, or copper-clad aluminum conductor. This conductor shall be solid or stranded; insulated, covered, or bare; and in the form of a wire or a busbar of any shape.

Dave Nix I'll bet there is at least one place the code specifies "insulated" EGC!
Ryan_J Would this be the same place that says "isolated"? Just a shot in the dark without looking in the book. Let me know, will ya Dave?

Yes, I would like to see that one myself.

Dave Nix Please look in 517, 518, 520, 530, 547, 555, 605, 610, 680, 800, 820 and 830!

Thanks Ryan!

Only made it through 555 in your list. All I have seen so far is that the code allows in certain situations, the ability to run a ground wire outside (or isolated) from the main current carrying conductors or an insulated ground that is part of a cable system. I will maintain that for normal, everyday wiring with conduit etc., bare ground or insulated are OK.

I know I'm being a little general here but going with the original question, I think I have that liberty.

Dave Nix Ok,

Yes.
quote:
680.21 (A)(4) One-Family Dwellings. In the interior of one-family dwellings, or in the interior of accessory buildings associated with a one-family dwelling, any of the wiring methods recognized in Chapter 3 of this Code shall be permitted that comply with the provisions of this paragraph. Where run in a raceway, the equipment grounding conductor shall be insulated. Where run in a cable assembly, the equipment grounding conductor shall be permitted to be uninsulated, but it shall be enclosed within the outer sheath of the cable assembly.
David Hyatt Good job Dave.
JimmyDee I stand corrected.
On edit: Maybe not. Article 680 is not for normal wiring. Its for swimming pools and 680.21 is for the motors associated with a swimming pool or spa. I'll stand with my original until proved beyond a shadow of a doubt.

Dave Nix Hi Jimmy,

Your original question didn't specify!

But to be fair, the answer to the original (certain size) would be NO.
