AC Reverse Polarity Indicator/Protection Circuit(120v/240v)

Very useful circuit to ensure that AC polarity is correct in a circuit or electrical equipment/device. A reverse polarity condition (Hot & Neutral Lines Reversed), will not allow current to flow into the circuit or electrical device. This safety circuit is ideal for certain types of transformerless power supplies, triac circuits, and other circuits where the hot/neutral lines must be connected to the proper location in a circuit.
