Abstract

An improved electrical power cord adapted to enhance the safety of an artificial lighted tree is presented. The electrical power cord has a three-prong safety grounded plug located at a first distal end of the electrical power cord, the plug electrically coupled to a multi-conductor cable comprising a neutral member, a hot member and a ground member. The electrical power cord also has a circuit protector connected in-line with the multi-conductor cable, the circuit protector including a fuse, or, a circuit breaker, having stationary and movable contacts operable between open and closed positions, and a manually operable reset button operably configured with the circuit breaker and electrically connected between said circuit breaker and the ground member for selectively actuating said circuit breaker for opening said movable contacts.

Claims (36)
