Abstract
A multi-component electric switch-circuit breaker module permits electric switches and circuit breakers to be field-installed within existing panelboard-switchboard enclosures. The module contains a pair of compartments that are accessed by separate doors. Electric switches or circuit breakers can be arranged within both compartments or an electric switch can be installed within one compartment with an electric circuit breaker installed within the other. The module is removably attached to the panelboard-switchboard interior by means of a bail handle arrangement. The module is removed from the assembly by unscrewing the bail handle and manually accessing the module. Spring-loaded connector clips allow for repeated connection with and disconnection from the systems power bus with minimum contact resistance.
