This schematic is an attempt to represent a breaker with its upper portion and below the primary test set. When current is cranked up 40mA approx the breaker picks up , lights up the yellow Led and starts counting. If current continues to increase up to 100mA approx, the breaker will trip, light up the red Led and timer will stop counting. Press push button to reset the counters and crank current back very low to turn off the Leds. Have fun, y'all, and praise Jesus for the inspiration
