ECN Forum Forums General Topics of the Trade General Discussion Area splicing grounding electrode conductor

Split bolts do the trick. I use them as described for multi family services.

I believe that the inexpensive exothermic welds being discussed are the One-Shot by Erico or the Uni-Shots by Harger. I use these quite often, anytime I must connect to a ground rod outside. But if memory serves me correctly, both these inexpensive tipes are used for rod to conductor connections. I think that for conductor to conductor or other configurations, you must use the standard graphite mold and charge version. I couls be wrong, but that's all I could find.

I think I see what you mean. I initially thought that the tap connection had to be irreversible. That rule, 250.64(C) applies to a splice in the GEC.

250.64(D) allows taps to be made to the GEC by conductors from a second enclosure without saying how, just that the GEC must be installed without a splice or joint.

I was so focused on (C) that I neglected to carefully read (D).

Thanks

You can use 250.64(D) for the two panels, but the common GEC has to be spliced with an irreversible type of connection.
Look back at (C).
