Abstract
Method and apparatus for minimizing exposure to live parts in the panelboard allow safe insertion and removal of a circuit breaker from the panelboard. The method and apparatus provide a shutter assembly that automatically closes off access to conductors in the panelboard until a circuit breaker is inserted in the panelboard. Inserting the circuit breaker in the panelboard causes the shutter assembly to open and allow the circuit breaker to contact the conductors. When the circuit breaker is removed from the panelboard, access to the conductors is automatically closed off again. Such a shutter assembly allows operators to safely insert and remove a circuit breaker and other electrical device from the panelboard.
