ABSTRACT:
An apparatus for a lock out/tag out device that is a permanent attachment to a standard breaker box is disclosed. The device is designed to prevent movement of an electrical breaker handle to a closed position when the device is in use. The device also prevents locking a breaker in an on position, thereby lowering safety concerns. When the device is not in use, the device will not interfere with the operation of the breakers and stays conveniently attached to the breaker box. The device also allows storage of locking devices when not in use, thereby enabling personnel to perform a service procedure more efficiently.
