发明名称 GFCI THAT CANNOT BE RESET UNTIL WIRED CORRECTLY ON LINE SIDEAND POWER IS APPLIED
摘要 A method and apparatus for a protection device for indicating when ground fault protection is not being provided by the protection device. The protection device includes source and load terminals between a conductive path and face terminals. The protection device further includes a latching mechanism, adapted to be operable between a first state in which the latching mechanism permits electrical contact between the source terminals and the lo ad terminals and a second state in which the contact is broken; an alarm indicator, adapted to provide an indication that the protection device is not providing ground fault protection; and a fuse, adapted to blow when the latching mechanism fails to open during a manual test of the protection device.
