I have been told that General purpose contactors are not UL listed. Does this mean that they can not be used for a commercial lighting control? Do commercial Lighting control systems have to have UL listed contactors?
I have a commercial project with 2 lighting panels and all the contactors are general purpose, not lighting type contactors. Mostly 3 pole 30 Amp w/120V coils. Running parking lot lights, building lights (about 12 contactors in all). These contactors are old and a few no longer engadge. The customer has agreed to replacve them, but is asking why we can not put the less expensive general purpose contactors in (they have a lighting maintennace co. that changes their bulbs who has in the past installed these general purpose contactors).
