Wire Nuts with Stainless Coils Required?

[Grandfathered In]

Are there circumstances where stainless coils in wire nuts are required by code in the USA?

I can see the definite advantage in damp environments. Are they required there or elsewhere?

FWIW, it doesn't look like the markings on the end indicate damp or not... perhaps that's implied in some other spec?

Never seen SS wire nuts. The idea is to keep moisture out to begin with. There are damp location wire nuts that have a grease in them that are used in those locations such as lawn sprinkler valve boxes. Otherwise, there are encapsulation kits that you put the splice in, and it gets filled with an epoxy or other compound to make it waterproof such as direct burial.

Regular wire nuts are for use in dry locations only.

Scotchkote!!! Any guy that I ever hired that knew of this stuff I immediately labeled him as service dept. material!

And the proof...somewhere in his service truck was evidence of spilled Scotckote after their 1st use.

Yep. Been there and done that. Can got stuck to the shelf.
I gave up on scotchkote and started using drycon wire nuts. Easier to use and can reuse

Old and retired, I've tried Liquid Tape lately. Scotchkote would outlast my great grandchildren. The LT, maybe me.

After you pry it off the shelf, how about trying to get the cap off.

I love ScotchKote. All my underground connections get it.

Yup. Crimp butt splice, a layer or two of 33+, Scotchkote. Then heat shrink, or the gel filled. Another layer of tape and Scotchkote probably would have been adequate.
