ABSTRACT:
A trouble light incorporates a circuit breaker in its handle to reduce the possibility of shock to a user. The handle is formed of right and left shells and includes a screw-type receptacle for a lamp and an electrical plug receptacle. The circuit breaker is connected in a series with a power cord, and to the screw-type receptacle and the electrical plug receptacle. The circuit breaker instantly interrupts power to the receptacles upon detection of excess current flow in the circuit in the trouble light. The handle shells are molded from an insulating material such as plastic and internal webs are formed to retain the various electrical circuit elements in the handle.
