Another interpretation of the question may be "Where is the NRTL requirement
strictly enforced?" (which is a much larger list than where it is
required.) Where can you get away without a NRTL mark? That depends in

This is probably true when an electrician is involved in a product

not require an electrician to install. They are either installed by the

I doubt that it should necessarily be zero. From my wire and cable days,
there are test methods to determine the halogen content of "zero

The truth is that an independent licensed electrician will not connect a

In commercial or industrial environments, there may be a Licensed
