First thanks for the responses from my other pool questions.I wired a pool no niche 120 volt luminare. 680.23(B)(2)(b)requires a #8 insulated copper equipment grounding conductor in the 3/4 pvc that feeds my luminaire which is fed with cord also in same pvc. In my pool j box I have #12 insulated ground from panel #12 ins gnd to sw 4 luminaire #14 ins gnd in cord to luminaire # 8 ins gnd to luminaire shell.With 1 #8 in pool box conected to #12 egc how is the #8 in box bringing pool luminaire to same potential as #8 pool bond conected to all metal at pool?Thanks for any help as I cant sleep, I dont think the ahj understands this as much as I.
