ABSTRACT:
A method for securing a circuit breaker having a movable actuator, which extends through a circuit breaker face plate and which has at least two positions, which comprises the steps of: moving a fastening portion of a main frame member of a circuit breaker movable actuator locking apparatus into an aperture located at one end of the movable actuator so as to seat the main frame member adjacent to the circuit breaker face plate; moving a first sub-frame member with respect to the main frame member so as to move a fastening portion of the first sub-frame member into another aperture located at another end of the movable actuator so as to seat the first sub-frame adjacent to the main frame member and the circuit breaker face plate; and moving a second sub-frame member with respect to the main frame member to position a blocking portion of the second sub-frame member so as to block substantial movement of the movable actuator.
