I have an existing installation at a shopping center. I believe a non licensed sign company did it orriginally. I was called out because another sign company was changing some lamps/ballasts and the technician said he was getting shocked when in contact with one of the poles. I realize there are too many NEC issues with the installation to list here so I will try to address a couple of questions. First, the lighting circuit conductors are run underground (in conduit). There are a total of 9 circuits. Each circuit consists of ONLY two conductors. There are NO equipment grounding conductors present and no "grounded" conductors. I believe they should be run with the ungrounded conductors for each circuit. Am I correct?
As I see it, if there is presently a fault to ground at a pole there is no way the OCPD will "see" it and there is a strong possibility that a voltage potential could be imposed at the pole resulting in the shocking.
All advice appreciated.
