How to lockout a circuit breaker?

Circuit breakers come in different models and sizes. Each circuit breaker type requires a specific circuit breaker lockout design for the lockout to be effective. Some common types of lockouts are clamp-on, tier bar, pin-in, and pin-out lockout.

These devices can be easily installed to the circuit breaker because of their convenient thumb screw or push button design. Once the circuit breaker lockout is affixed to the breaker, the authorized worker can use a padlock to securely keep the lockout in place and accompany it with a tag to relay information to other workers.
