Correct answer to question 15060
- B: To provide a low impedance path so overcurrent devices open during a ground fault
Explanation
An effective ground fault current path allows enough fault current to flow to operate the overcurrent device quickly, removing dangerous voltage from exposed metal. This reduces shock risk to workers.
