UL 508A Frequently Asked Questions

Q. Most of the discussion has been around components? What about wires and bussing? Does that figure into the equation.
A. The wire does not need to be looked at. It’s inherently tested so when correctly wired, it should be ok. Bus bars automatically receive a 10kA rating unless the device has been tested with UL at a higher level fault rating.
