    Greetings CQD,

    Does the natural gas (NG) external piping, regulator, meter and all the threaded connections require electrical grounding per the national or any other codes pertaining to NG? I am being told by the Gas Company no because they have a plastic fitting (elbow) between the ground being provided on the house side which is proving a ground for my gas appliances. This seems strange to me that they are not grounding their equipment. How does this act if lighting hits their equipment?
