That will have to be an Article 511 installation. 511-10 requires GFCI protection for any receptacles that will be used for portable repair and diagonstic equipment. You will also have to deal with Class 1 Division 2 locations, maybe even Division 1 if there is a pit. If it is a wet location then weatherproof covers will be required. The specs for the job may exceed the NEC requirements and must be complied with per the contract. They are not enforcable by the electrical inspector, but are enforcable in civil court.
