Grounding Electrode Conductor Connection/Splice

[Canton]

I have a residential 200 amp heavy-up. The existing #4 GEC from the cold water is to short and will not make it to the Neutral/Ground buss. It will make it inside the panel but being a different panel manufacturer now it will not make it. I have the inspection tomorrow and will not be able to get a High-Press buttsplice.

Can I put another ground bar in the panel (Square-D QO Panel) down low where it will reach and then put a #4 jumper from that ground bar to the Neutral/Ground buss where the Service Neutral is actually located in the Service Panel.

I know its all the same continuity wise, but trying to find the verbiage in the code to make it legal without going with the irreversible splice......Thanks

I say yes because you are using the wire jumper between the two busses.

250.24(A)(4) seems to maybe allow this, but the jumper would have to be sized using T250.66 per 250.28(D)(1).

I think also you would need a isolated neutral bar because a ground bar bonded to the can would be a parallel path for neutral current and this would seem be a violation of 250.6(A).

The whole service is a violation of 250.6(A).

I came to the same conclusion..
