Clarification: A separate structure (commercial trailer) with wheels removed being used as an office and storage is being supplied with 120/208 volts and is feeding a panelboard inside the trailer. The temporary feeder is a non-metallic cable assembly not known if hard usage and the supply power is being supplied from a panelboard inside a permanent building.
The temporary cable feeding this structure has been in place for 3-5 years. The cable feed from the permanent building is lying on mechanical room floor and passes through a metal louver vent outside to the separate structure. Outside the cable is run lying on the asphalt. The cable is exposed to employees/pedestrians and a portion of the cable is exposed to vehicle traffic and physical damage. The cable run is on the floor/pavement with no supports or protection.
I am being told this is a compliant temporary installation. After looking at article NEC 90 and 1910.304 & 1910.305 I believe this is a stretch.
