Using Spiral Wrap inside a Control Panel

[LarryFine]

Doesn’t that make it hardware...so no Listing? Sort of like whether cable tray is support or bonding?

In that case, why would wrap be any different?

Wondering if using Spiral Wrap is prohibited anywhere in the NEC. Some manufacturers show their Spiral Wrap as being UL Recognized and others don't have any markings whatsoever. Any clarification would be appreciated. Thanks!

in general what is inside a control panel is not controlled by the national electrical code. In fact the national electoral code does not prohibit the use of spiral wrap in a NEC compliant installation. It is a lot like wire ties. It just isn't really covered for the most part.

All the 100 or more ICPs I have installed were UL508B. In my state Art 409 is not referenced. I can build an ICP, but all the parts have to be UL listed, (many common parts like terminal blocks are UR for use in a 508B panel.

Do you have a link to the WAC or RCW that removes art 409 from the NEC ? I have never found such a reference.
I have read these:

Electrical Laws, Rules & Policies

WAC 296-46B-010:

And from what I can tell its in the NEC as adopted by Washington.

UL508B has nothing to do with industrial control panels.
