Hello, Pump motor and heater are both on dedicated GFI circuits of the
proper voltage and amerage. Copper pipe is part of the service panel
grounding electrode system. NEC 680.73/74 says that "bonding of all
the tubs metal parts is required". Is this simply a matter of using
the required #8 solid copper wire to attach these 3 things together?
Why is there no reqiured tie in to the service panel or grounding
electrode system? Thanks for helping me with a question that must have
been asked many times before. D. MacQueen
