NEC 110-3

[jimcollister]

Have installed a 460V service to operate a temporary, portable air conditioning unit in Las Vegas, NV. Inspector is siting NEC 110-3b as a discrepancy and will not approve meter for service. Does this section of the code apply to temporary, portable equipment/appliances? The a/c units were built using all UL listed parts and has a NEMA 12 rating on the control panel.

Re: NEC 110-3

You have not provided enough detail of that exact method of wiring and materials used to connect this equipment. Obviously, the inspector feels the A/C's are not istalled per the listing and directions of use. Article 110 covers provisions for the entire NEC, unless modified in other sections of the code. Simply because it is a temporary service, it still must meet requirements of the code standards.
