When cycling a circuit breaker, how long should you wait before resetting?

• A. 5 Seconds
• B. 15 Seconds
• C. 30 Seconds
• D. 10 Seconds

Answer: (B)

Waiting about 15 seconds after cycling a circuit breaker lets the electrical system settle. Right after a trip, transient currents, residual charges, and brief voltage fluctuations can occur. A 15-second pause gives the bus voltage time to stabilize and helps reveal whether a fault persists when you reset. If you reset sooner, you risk an immediate re-trip or chasing a transient that would clear on its own. Waiting longer than necessary just slows troubleshooting. The 15-second interval strikes a practical balance between allowing settling and keeping the investigation moving.
