Re: I-beam clamp NEC approved??


You are not going to find your answer in the NEC. The NEC is only going to say you have to use a "Listed Device" to do your ground connection. Your question is actually a Listing question, IE: is the clamp you are using listed for grounding, if it is the WB guy is wrong, if its not, he is right.
