Can anybody explain the 2 questions on pages 154 and 155 in the Mike Holt Understanding the NEC book?
In the question on page 154 i don't understand how they got the answer 14awg wire. I see how they are getting the amperages but how are they determining what wire to use and how do they know what type?
In the first question on page 155 im not understanding how they are getting 12awg, it says the minimum circuit ampacity is 23A, i thought you would have to use 10awg since it was good for 30amps?
