crawl spaces and ground wires

[jjsgranpa]

Just wondering.....is a primary ground wire from a service entrance box allowed to be spliced under any circumstance. Specifically in a crawl space?
I was recently asked about this by a Home Insoector and I wasn't sure how to answer him.

If you mean the grounding electrode conductor, it can be spliced but only if you use irreversible compression-type connectors or by the exothermic welding.

You can not splice it with a split-bolt connector or anything like that.

Look at 250.64(C)
