Re: 2005 NEC

Do you think that they intend for cut-out lamp holders to qualify as the disconnects?

Jim no, the cutouts disconnect the lamp. This proposal is for the ballast.

. . . to disconnect simultaneously from the source of supply all conductors of the ballast, including the grounded conductor if any.

One of the problems I see with this phrase is its demand that all conductors be disconnected. I really don't think we should be disconnecting the grounding conductors but the new Code language demands that we indeed do disconnect all conductors. HMMM

I think the terms, "of the ballast" disqualifies the EGC. I personally have never seen a ground wire from the ballast itself, usually the housing is bonded.

I think a reasonable case could be made that the grounding conductors are not part of the source of supply.

Re: 2005 NEC

What we will see will probably be quick connectors similiar to what we find on the back of smoke detectors included with our ballasts.
