Eaton wraps copper tape (they have yet to share the specifications) on type W cable (I believe it's class H stranding) and terminates it on their factory wired substations for marinas. I have asked a couple of times if that's a listed termination method. They dance around the question and never answer.

So, I'm asking y'all. Do any of you know if that's a listed termination? Do terminations like this need to be listed?

If you are an inspector, and you came up to a job and saw this type of termination (class H stranding with copper tape under a standard breaker lug that is not listed for class H stranding), would you ask questions or would you just look and move on? What questions would you ask?

Thanks to all that reply.
 
It is part of a factory manufactured listed device. I don't see an issue.

I think it is a perfectly good way to deal with fine stranded wires, it just does not meet code if it is done outside of a listed device.

That is a GREAT read, thank you so very much! Is that a SQD document that would only apply to SQD?

You said it does not meet code if done outside of a listed device. I'm not sure I follow. The panelboard is listed, I assume the enclosure will be, so does that mean in your opinion I can use this methodology to terminate fine stranded cable on breakers?

no. it likely means that UL has investigated the procedure by which Eaton does this and has accepted it for use in this equipment. It does not mean anyone else can do it unless they also get UL's blessing.
