Thanks a lot guys. I'm not real happy on solely relying on the conduit as the grounding conductor but I guess I'm not writing the standards either. Lots of help though, thanks again.

Does anyone know the rules for when running a two wire single phase circuit in an industrial setting is allowed? I'm having trouble getting a straight answer back on this and have been looking in the NEC 250.118 because this is what the company stated exempted them from needing an equipment grounding conductor present. I had been told in the past that only three wire single phase circuits were permitted in industrial settings like this one, however, if this is true then I'm having trouble finding it in the standards. Other information: Circuit run in EMT conduit, 50 - 60 ft from breaker box, four feet in height off floor adjacent to conveyor lines, with three metal four-plex receptacles, high (forklift) traffic area, 7 employees regularly in area. Any help?
