Definitions
- the collector 442C of transistor 442 is connected to a plus 5 volts potential such as is present at terminal 414 of Fig. 1 , and through a resistor 446 in series with a light emitting diode 448 to the emitter terminal of transistor 442.
- the emitter terminal of transistor 442 is also connected to the neutral terminal 416 of FIG. 1 through relay coil 450 operatively coupled to a set of contacts 452. When base 442b of transistor 442 is energized, this 5V DC current is passed through coil 450 thereby causing a triggering of switch 452 to move switch 452 into a closed position.
- circuits 400 and 429 can be coupled to different fault circuits such as a GFCI, an AFCI or any other type of circuit which where this circuit would be applicable.
- power circuit 400 and ground sensor circuit 429 can in at least one embodiment be coupled to a standard ground fault circuit interrupter (GFCI).
- FIGS. 3-6 disclose some of the general components of a GFCI.
