I just installed a new 480 volt 3 phase water heater and get a reading of 3/10 amp on the EGC. The conduit is used for ground from the switchgear to the heater disco; green wire ground from disco to heater. Is this a bldg ground problem or is the problem with the water heater? Any advise would be appreciated.
