I try to be careful not to say "U/L" listed, simply listed. Listing indeed is a "crutch" or a "tool" depending on who you talk to. It establishes a minimum stanndard of performance. In an industry that is trying desperately to establish some standards I welcome it. We still have 90-4 to "approve" unlisted items but I think they should substantially meet the same standard as a listed item.
Electrical contractors should appreciate a uniform electrical standard so they are not building a different installation depending on city/county lines and what Bubba the inspector is feeling like today.
