Electrical circuit breaker safety system

A system for preventing actuation of a push-pull circuit breaker knob, the system comprising:

• a clip member having a generally C-shaped collar defining a cylindrical recess therein, wherein the clip member resiliently expands to be positioned over and receive a cylindrical portion of the circuit breaker knob;
• first and second tabs depending from free ends of the clip member, the first and second tabs forming a restricted opening for which the cylindrical portion of the circuit breaker knob may be snapped into the recess, the first and second tabs having openings therethrough;
• and
• a retainer coupled to the first and second tabs in a manner that prohibits the first and second tabs from being urged apart and the clip member from expanding sufficiently to permit removal of the clip member from the circuit breaker knob, thereby locking the clip member in position on the push-pull circuit breaker knob and preventing the circuit breaker knob from being depressed.
