Re: Ampacity Question
C for derating purposes, and B for final reuslting ampacity. What do you think?

Re: Ampacity Question
There are many questions similar to this one on many standardized electrical exams. Some takers will be tricked into thinking conductor proection is the same thing as conductor ampacity.
In this example, the circuit rating is 15A. The overcurrent protection required is limited to 15A, however the conductors could be loaded to 20A before reaching 60? C.

Re: Ampacity Question
It's the same thing. The 40A breaker is not an overload device, it only protects against ground-faults and short-circuits. The NM will still be protected at its ampacity by motor overloads.
