Correct answer to question 3031
- D: When GFPE is provided on the supply side of the feeder
Explanation
An exception to 215.10 removes the requirement where ground-fault protection is already provided on the supply side of the feeder and on the load side of any transformer supplying it. A continuous industrial process where a nonorderly shutdown adds hazards is also exempt.
