Abstract
An apparatus is provided for mounting on a circuit breaker to tag or indicate that an electrical line or equipment connected to the breaker is being serviced. Once work has been completed, the apparatus can be removed from the circuit breaker for later use on other breakers. When in place on the circuit breaker, the apparatus keeps the circuit breaker switch or handle in an open or off position, while also enclosing the switch to render it inaccessible from inadvertent contact.
