A single-phase apparatus and method having a component-efficient circuit configuration for protecting AC power lines from power surges and preventing the hazardous condition occurring at the wall receptacle which arises from accidental reversal of the line wire (L) with the neutral wire (N), from adversely affecting peripheral devices attached to the line. Protection is achieved by removing operating power from a relay having normally-open contacts to simultaneously disconnect both hot and neutral power lines, but not the ground (G), feeding the peripheral device when the over-voltage event occurs in any of three wire pairings: L-N, L-G, or N-G. A lighted indicator warns that the apparatus has absorbed an excessive energy and has opened the circuit.
