I am wiring a motor in a paint booth Class I Division I the motor must be able to be moved up to 5 feet. NEC 501.4 (2) Flexible Connections & 501.11 say that if I use a listed extra-hard usage cord And meet the conditions of 501.11(2)-(5) It is OK can you think of any other things I should know?

Re: motor in paint booth
This sounds like a violation of 516.4(D). In general, Art 516 doesn't like portable electrical equipment in spray booths. I don't know your installation or process well enough to make another recommendation.

Re: motor in paint booth
You can buy cable seal assemblies from several venders, but they come with a red tag on them indicating the assembly is not UL listed even though it consists of two UL listed peices - a standard seal and a cable busing.
So if you need a UL listed assembly as a cable seal, you may well be out of luck.
I ran into a similar situation once. We ended up using hard service cord (not in a paint booth though). However, it turns out no one makes a UL listed cable seal assembly. I was told UL has taken the approach that they will not list a cable seal assembly because the cable cannot be easily replaced.

Re: motor in paint booth
"Listing" is not the issue here. If you carefully review all the relevant code[including 500.8(A)(1)] for cord applications, listing is only required for the individual components - not the entire "assembly" itself.
However, in addition to Art 516 not generally liking this application, Section 501.11 still has some severe restrictions beyond Subsections (1)-(5). The Subsections only come into play after all the other "industrial establishment" maintenance, engineering supervision, "qualified persons," location, etc., provisions are met.
Spraying operations can be extremely dangerous, which is one of the reasons they have their own unique Article.
