mikesh,Whats confusing me is the wording of 2-024.It does not specify voltage or class and seems to say that whether the parts are individually approved or not once you use these parts to build a peice of equipment it has to be approved as a whole.Maybe I'm reading it wrong.The wording in sub-rule (3) just throws me off. Thanks again
