Sorry for reposting already closed thread but that sketch previous post maybe not clear and just want to make sure.
Attached sketch shows main service disconnect with grounding electrode conductor to external bus. The external bus has bonding jumper to steel, bonding jumper to water pipe, bonding jumper to underground metallic gas pipe and other metal pipe.
Is the underground metallic gas pipe used as grounding electrode?
