We have a Pump skids in Class 1 Div 2 and Gr D location with Explosion proof motors and class 1 Div 2 rated pressure switches. There is a Explosion proof (NEMA 7) Junction box with Start/Stop switches and pilot lights. The skid fabricator used Thomas Bette PVC coated rigid steel conduit and ordinary purpose conduit fittings (Form 7, such as 90 degree elbows) to run wiring between motor (s) and Junction box. Can you please advise if these ordinary purpose fittings and rigid threaded PVC coated conduits are acccpetable for Class 1 Div 2 Gr D location. Also advise what kind of sealing/Bonding required at the junction box termination point.
Thanks
