You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.

Bonding in swimming pool language is the use of a number 8 gage wire connecting all metal parts. That #8 bonding wire starts with the wire cage or re-bar in the pool shell. It continues to the grab rail, if there is one, then to the pool light, metal rope hooks, if they are present, to the pump, the heater, the time clock etc. It is sometimes what some people would call a double ground wire or redundant ground. k
