UL question
(OP)
I am using a 75VA isolation transformer to power controls for a gate operator. I cannot find anything in UL325 that mentions the specs for the primary fuse, only secondary requirements....does anyone know if UL cares about the primary fuse or is it just an NEC requirement? OR am I looking in the wrong place? There was mention of UL 1585, but I don't think I have a copy of that...






RE: UL question
UL would care only if the fuse is integral part of the assembly being tested for UL listing.
