I have a question on where in code that a pier must be wired in conduit and that the ground wire must be insulated. I can not find this in code and I dont disagree with the wiring method I would like to understand where it is coming from. I have always wired a residential pier in PVC conduit using copper wire THHN with insulated ground wire but can not find the reasoning in code other than that is the way it has always been done. The Inspectors site that, that is code but also only site wiring methods. I question then if that is case why the insulated ground wire when code allows the use of insulated or bare. This is not a boat yard or marina. The reason for the question is have so many piers that are wired in UF wire and when we come to repair or rewire pier the customer always asked why can't we use UF wire. As a side note the piers are wired for boat lift or jet ski lift and maybe simple lighting.
