Which procedure involves pulling the affected circuit breaker, waiting 15 seconds, and then resetting it?

• A. CYCLE
• B. CHECK
• C. RESET
• D. CHECK/RESET

Answer: (A)

Cycling a circuit breaker means turning it off, waiting a short period, then turning it back on to restore the circuit. This helps clear transient faults and ensures the breaker contacts settle before re-energizing the system. In this scenario, you pull the affected breaker to OFF, wait 15 seconds to let any residual energy dissipate and the fault condition reset, then reset it to ON. That exact OFF–wait–ON sequence is why this option is the best fit. The other approaches don’t describe that controlled power-restoration cycle: a simple reset wouldn’t guarantee the fault is cleared or the contacts fully settled, and checking or performing both check and reset adds steps that aren’t part of the described cycle.
