Hi Gents,

I have an installation where I need to bring grounding wire into fiberglass control panel to bond to ground bus inside the control panel. The ground wire will be bottom fed into the panel, should I just drill a hole and put a gasket around the wire?

Thanks,
EE
 
Is the reason for the fiberglass enclosure due to water and possible corrosion issues? I have no clue what you are thinking of in terms of a "gasket", but they do make non-metallic water proof fittings that basically have a rubber insert with a hole in it. Install the fitting in a 1/2" KO, run the wire through the fitting, tighten it up and it squeezes around your wire.

If water is not an issue you could just use a Romex connector.

I would like to see either rather than just a hole.

I used to do this but I don't any more Romex connectors would.be a violation as there not listed for that purpose

Cord grip - if the wire is a small one wouldn't even need to be one with 1/2 pipe threads, there are miniature grips for smaller wires/cables.

Said wire doesn't necessarily need a fitting listed for the purpose, and is kind of chicken Sxxt for someone to reject it for that reason. Is there other connector that is listed for an individual conductor? Even the cord grips possibly don't really mention individual conductor vs multi conductor assemblies in their listing/instructions.

Rejecting it because it doesn't maintain NEMA 13X of the enclosure I can buy, or rejecting it because it is metallic and needs to be bonded I could buy.

If N3R is all that is required for the enclosure then drill a hole not much larger than the conductor and don't put anything else around it, as long as entering the bottom wall.
 
What's a grounding wire? If it's a GEC then a small hole like those typically used when going into a panel would work.

GEC or any other bonding jumper for whatever reason should still work.

True EGC's should run with the circuit they are associated with in same raceway/cable as the circuit conductors.

That was my question, he said "grounding wire" in the OP, sounds like a GEC but could be an EGC.
 
Are cord grips listed for single conductors? I think that something like a Kenny clamp would be the only code compliant connector.

Do they need to be? For a ground/grounding/bonding conductor? If it were a current carrying conductor that is different - but would be much more rare to not have some type of multiwire assembly with all conductors of the circuit in those cases.

If I can legally run the conductor through a hole with no fitting why does it matter if I run it through something else as long as it doesn't create additional performance issues? Like a metallic fitting and inductive effects that may happen. Presuming the cord grip in this case will be non metallic, I don't have a problem with it outside of some inspector that looks for every little thing no matter how sensless it may be. Someday I expect something will be rejected for not using listed mounting screws, and will have to ask if those are even required to be listed for that particular application:(

I see no difference between a cord grip and some other connector that's not listed for the purpose. Is it required to be listed that's another question.

I don't see why it should matter if I use a cord grip (listed or not) for something that can otherwise simply be run through a hole in the wall of the enclosure.

Had similar disagreement with an inspector once on using staples that are listed for multiple NM cables but used to secure MC cables. Yes they were listed - but not for MC cables. At same time no listing is required for a product used to secure those cables. Inspector would pass non listed "wire type" staples, though it was much easier for installer to over drive them and damage the cable than the "stacker" NM cables that had somewhat of a built in "stop" that I wanted to use. All I could do is :slaphead:
