Im an inspector. I had a contractor replace a subpanel in basement (main disc. outside at service) and reconnected to existing 3 wire SE with uninsulated neutral to the replacement panel (SE length 60' - 70'). I was wondering if anyone would concider the SE to be "existing" and OK the replacement panel? Would anyone allow the contractor to run a separate GEC from water meter to subpanel and to main outside? Or because neutral is uninsulated would it just fail on that basis?
