Hazardous location motors are listed

Right everything 'Hazardous location' needs to be listed. Interesting thing there, as you probably already know, is there IEC IECEx and Zone System has become the main system used world wide and is even in the US CFR's now.
But no blanket motor listing requirement in 430.

That listing probably more for the hazardous location reasons than for general electrical reasons as well. And may not necessarily be UL that lists it.
