Grab your code book and read Article 501- it spells out what is acceptable for wiring methods and sealing.

Specifically it is 501.10(B) for wiring methods and 501.15(C) for sealing. However you may need to also at other Articles/Sections depending on the type of installation i.e. dispensing station, bulk storage, etc.
