I have an outside 200 amp diconnect with a 4 - wire system for a single dwelling, i installed 2-ground rods for my main grounding. The water line service is plastic. Can i bond water lines at sub-panel or does the bond go out to means of disconnect or ground rods.
Thanks, thats the way i'm reading it in art:250.104-1. But since this water line is not a ground could this be under (other metal piping) Art:250.104-(4)(b)where the equipment grounding condutor for the circuit that may energize the piping shall be permitted to serve as the bonding means.
