• Replacement: If any damage is observed, or if the device no longer secures properly, replace it immediately to maintain safety standards.

6. Troubleshooting

If you encounter issues with your Brady Clamp-On Breaker Lockout, consider the following:

• Device Does Not Fit: Ensure you are using the correct size lockout device for your circuit breaker. This model (65966) is designed for 480/600V breakers. Utilize the included detachable cleats if the standard fit is loose or unstable.
• Thumb Wheel Not Tightening: Check for any debris or obstruction in the thumb wheel mechanism. Ensure the device is correctly aligned over the breaker switch tongue. If the thumb wheel spins freely without tightening, the device may be damaged and should be replaced.
• Padlock Does Not Fit: This device accepts lock shackles up to 9/32 inches (approximately 7.14 mm) in diameter. Ensure your padlock shackle meets this specification.
