Re: bonding of covers
Bob,
I don't think that the word "likely" is involved in the answer to this question. It is my opinion that 250.4(A)(3) requires bonding.

Re: bonding of covers
I'm not sure (3) would apply.
Is conduit considered to be electrical equipment?
Equipment. A general term including material, fittings, devices, appliances, luminaires (fixtures), apparatus, and the like used as a part of, or in connection with, an electrical installation.
One might be inclined to think from this definition that raceways are not equipment.
And can you stretch the meaning of the word "enclose" to include such a lid? the lid certainly does not enclose anything by itself.
Enclosed. Surrounded by a case, housing, fence, or wall(s) that prevents persons from accidentally contacting energized parts.
I guess I was thinking more along the lines of 250.4(A)(4).

Re: bonding of covers
Intuitively, I agree with Don. As for the Code, well...I agree with Don here too that 250.4(A)(3) applies. If you look carefully at the wording of 250.4(A)(3), it says "... equipment, or forming part of such equipment ...". IMO, that means the cover to the enclosure as well. That being said, of the few manhole and handhole covers I have taken off, I don't remember seeing a bond anywhere, but I guess I wasn't looking for it at the time.
