Thanks jlarson, providing the ul number opened up a vast search on google.
I have always seen this exception in the code that works around going 125% for stuff like continuous loads.
Exception: Where the assembly, including the overcurrentload.
devices protecting the branch circuit(s), is listed for operation
at 100 percent of its rating, the ampere rating of the
overcurrent device shall be permitted to be not less than
the sum of the continuous load plus the noncontinuous
I wasn't sure if I had ever seen a device rated at 100 percent before. I still would not use the exception, or if that would fit it. Is a breaker in free air when installed in a panel with other breakers?
