UL Listing
UL Listing
(OP)
Some folks at my place of employment have become concerned about the modification/ additions we are making to our products. Our product is UL listed, we often modify it per customer specifications. This may involve the addition of breaker and enclosure, for which both our product and the additions have to be modified. This modification applies to the sheet metal enclosures, cutting, drilling, and such. Can anyone provide advise, or a reliable reference?

What type of UL listing?
If you list under UL508A - Industrial Control Panels then you follow certain rules to make a control panel. If you list under UL508 - Industrial Control Equipment then you can only build what's listed in your file.
Advice?
Call your UL rep.
Go to a UL seminar - someone at your plant should have a better understanding of what you need to do to maintain your UL listing.
