NEC 409.3

[Rocinante]

Hi, all! I work for a place that typically outsources industrial panel design and building. As such I don’t have someone here to ask this. It’s my general understanding from reading various articles and forums that the NEC “stops” at the supply conductors termination point. However, reading 409.3 I am curious if it does in fact apply to the internal wiring. To be more specific, does 409.3 now require that ICPs with motor control follow Article 430? How about Article 210?

This is true for Listed equipment. The NEC still applies to what you do in your shop.

So, to clarify, if a panel we purchase is not listed all of the things in the panel now must comply with the NEC?

Yes.
