If you are protecting cable with a 100% rated breaker, should the cable be larger than it would be with an 80% rated breaker. e.g. if I've got a 1000A feeder, does my cable need to be rated for 1000A x 1.25%.
I believe cable is fully rated for whatever is listed in Table 310-15(B)16 but I'm having a moment of doubt.
thanks,
Mike
