Question:
Hello Code Friends,
Can a water pipe ground clamp be used to connect a grounding electrode conductor to a rebar in a concrete-encased electrode? We have run into an inspector that has cited us for doing just that. Can you offer an opinion to help?

Answer:
Hello Wilson,
Thanks for participating. Listed clamps used for connecting conductors to rebar for concrete-encased electrodes should be identified for that use. If the clamp is marked "Direct Burial" or "DB" than it is suitable for direct burial and concrete-encasement, based on the information under UL Category KDER.
