"(C) Continuous. The grounding electrode conductor shall be installed in one continuous length without a splice or joint, unless spliced only by irreversible compression-type connectors listed for the purpose or by the exothermic welding process."
I'm thinking that I could, not that I would want to, but could, splice the gec in the panel. Please correct me if I'm wrong.
Yea...you can splice the GEC.
You said it yourself.....Irreversible compression type connector......exothermic welding process......
As for the OP.....As Iwire and Roger said, where does the code say that you can't splice grounding conductors in the panel?
Most branch circuit grounding conductors get spliced numerous times (every time it enters a box and attaches to a device).
Why would it matter if it was spliced again in a panel?
Continuity is the key.
