Hope I am not wasting anyone's time but why is the minimum ampacity of a conductor 1.25 times the continous load. Why the 1.25 factor again? From what I understand you do not need to apply this factor if your circuit breaker is rated for 100% operation.
I always check to make sure the max load on a wire is not greater than .8 times the circuit breaker rating, in this case am I double counting this factor? Once for minimum cable sizing and one for 80% CB operation? Hope my qustion makes sense
Thanks
