At our plant we are taking out a cooler (long steel belt with water spraying down on top of containers) and replacing it with a new one.
The original had one large drive motor and one large pump possibly a blower. The new one has 5 Pumps, a drive motor, outfeed belt & 2 blowers.
Needless to say, it is going to take a little bit more power to run the newer one.
We normally do everything in house, but for bigger jobs, we hire outside electricians, in this case, have them run some mains over to a new control box.
The said that the problem with that is, the new box that I would assemble, would have to be UL listed. This is the first time I've heard of this and I've done a few new panels and/or replaced old ones in the four years I've worked here.
So my question is.... What are the requirements for such a thing? Does it have to be UL listed, because all the individual Parts will be (Allen Bradley {Switches, Starters, Breakers, Transformer}, Paunduit Wireway, Hoffman Box)?
Some light on this subject would be much appreciated. I've searched the forum already, and the answer was still not very clear to me.
