Electrical Panel Ground Splice

[ducatithunder]

I have a 28x46 shop that had the ground wire for the electrical panel bonded to the foundation rebar and rod prior to pouring remainder of the stem wall foundation. Since then I have decided to move the location for the proposed panel to another location within 15 feet of the original stud bay were the ground wire is located.

My question is can I splice the ground wire with split bolts in the wall and run it to the new panel location or do I need to install 2 new rods outside the building. Id rather not put a hole in the exterior wall for this if I can use the original ground wire.

Thanks.

No. The grounding electrical conductor splice must be made with an irreversible crimp connector, or exothermic welding (Cadweld).

Note that I didn't comment about the way I might do it if it was mine and couldn't see it as splits are not compliant and wouldn't pass a legitimate inspection.

I didnt think about copper crimps at the time. Now that it was mentioned that appears to be the best route. The split nuts were easy and I have seen them used outside on older construction. I will use the burndy copper crimp.

The idea of splicing the ground wire to add the needed length was really what I was after. I cant say Ive ever seen the ground wire run though the wall other then down the stud bay directly outside to the rod.

Sberry ... would you do it differently?

Thanks for the advice!

No, use the crimp.

The Code cite is here:
250.64
(C) Continuous. Except as provided in 250.30(A)(5) and (A)(6), 250.30(B)(1), and 250.68(C), (it doesn't comply with an of those mentioned) grounding electrode conductor(s) shall be installed in one continuous length without a splice or joint. If necessary, splices or connections shall be made as permitted in (1) through (4):

(1) Splicing of the wire-type grounding electrode conductor shall be permitted only by irreversible compression-type connectors listed as grounding and bonding equipment or by the exothermic welding process.

(2),(3), and (4) Don't apply in this case

I like cad welds my self having done tons of them for microwave radio towers

Thanks guys.
