Our UL inspector (not my favorite guy anyway) Is refusing to rate some control panels because some door mounted devices do not meet UL-50.
They are UL-508 and are listed in our file. They are NEMA 12/4 rated. According to the inspector (a worthless pedantic git) manufacturers must submit the devices to UL for testing, as apparently NEMA is not good enough.
I've felt UL-508 was a racket for a long time, and this UL-50 is clearly a revenue generating gold mine (non-profit my butt). However, I'd like to know how many of you are experiencing this, what the rationalization for it is, and how long it has gone on.
