Do aboveground pool codes differ? I have a oval 33' that is one large sheet of steel connected together at the skimmer. There is a wooden deck surrounding the pool. The 110v pump uses a 3 prong plug into a GFI connected to the main panel thru 4 conductor romex. All pipes and ladders are pvc. Should the pump be bonded to the pool? Should there be a separate ground from the pump to the panel ground?
