Just fine at normal temps, not so sure for on-roof application
The description says "All MidNite circuit breakers hold 100% rated current independent of ambient temperature" but either this is not actually correct (as temperature affects the trip current for every other similar device that documents the dependence), or I got a faulty unit. Either way I would not use this in e.g. a Soladeck but rather a relatively cool indoor enclosure.
