is there any code section in NEC that states they will allow us to exceed
the 80% rating of a main service breaker, if the breaker is 100% rated
device? IE if there is a 200A service and your demand load exceeds 160 amps
at 277/480v-3ph-4w, can we spec the breaker to be at 100% rating and keep
the feeder at 200 amps?
