On a 200 amp residential service.I have a back to back.Meter out side and 200a main breaker panel on the inside.I use pvc nipple between the wall.Iam a licensed journeyman in Florida been in the trade 18 years. Years ago an Inspector in town of Palm beach Made me take the 4th wire out of the nipple going to the main panel (the grounding electrode conductor)He mentioned something about paralleling it was not right because it could get a load on it.I used to always think going from the ground Rod or Rods with my # 4 through the meter can bonding lug and then to the bar on the main panel it was better.And I was taught that way by fellow workers.Anyways I did what the inspector said and for years I only take the #4 from the rods Directly to the meter can.And had no problems.Untill I move to Indiana last year.These guys in my company say Iam doing It wrong.they want to go to the panel with the gec from the rods then come back to the meter with the #4.I try to tell them what I was told and read article 250 over and over.To try to get the real answer to this.I do it the way they say because There paying my Bills.But I really would like some feed back.The way I read the code It says You can Hit the meter can Or the first disconnect whatever is more accessable .I don't see why you would do both and is it wrong To do both.The 3/0 neutral is the ground attached right to the can Of both???????please help
