Bruce I assume when you say grounded you are talking about the connection to the grounding electrodes, water pipe, ground rod etc.?


If so then the answer to your question is that it is acceptable.

Quote:
250.24 Grounding Service-Supplied Alternating-Current Systems.

(A) System Grounding Connections.

(1) General.
The connection shall be made at any accessible point from the load end of the service drop or service lateral to and including the terminal or bus to which the grounded service conductor is connected at the service disconnecting means.

Maybe Bob or Greg can give us their interpretation as to what is acceptable.

Well that would be tough as the NEC does not state how many feet are acceptable. icon_lol.gif


In my area we are limited to about 5' of service conductors inside the building.

That said it is not that hard to be compliant.

1)There could be a service disconnect at the meter which would also mean that the GEC would have to go there.

OR

2)The service conductors run as far as you want outside the building and only travel inside the building a short distance.

thanks guys, and yes bob I do mean grounding rod at the meter. when I was in Ky the local was max 10’ but the grounding conductor was always there. I just would have thought that they would want to see the ground in the panel. and forget the water lines all I see down here is plastic. damn i miss copper. icon_biggrin.gif


PS
Jeff, congrats on breaking 3000 post. keep up the good work
