Here's a the situation:
A rigid metal conduit is ran from a MCC to within 3 feet of a 480V-3ph motor. Non-metallic sealtite connects the conduit to the motor and a proper size ground wire is ran along with the motor leads.
The question: Is a grounding jumper wire required on the outside of the non-metallic sealtite, or is the ground wire inside the conduit sufficient (assuming the ground wire is connected properly on both ends)?
