I am working on a project that uses an SCR to connect the hot (170Vp 60Hz) leg of an outlet to the neutral and trip the connected circuit breaker. I also have a transmitter circuit connected to the same two prong plug as the SCR. I am using a normally open switch and 9V battery to trigger the gate of the SCR and latch it. When the SCR is latched by closing the switch, and the hot and neutral are shorted, the breaker trips as it should. After this the SCR remains latched, keeping the hot and neutral connected. Is there any suggestions on how to unlatch the SCR? There should be no current through the terminals once the breaker trips.
