Chapter 3, Problem 28R
  1. a. A 25-ampere branch-circuit conductor is derated to 70%. It is important to provide proper overcurrent protection for these conductors. The derated conductor ampacity is ___________________________________________________________________________________________________________________________________
  2. b. If the connected load is a “fixed” nonmotor, noncontinuous load, the branch-circuit overcurrent device may be sized at (20) (25) amperes. (Circle the correct answer.)
  3. c. If the above circuits supply receptacle outlets, the branch-circuit overcurrent device must be sized at not over (15) (20) (25) amperes. (Circle the correct answer.)
