A surge protector for alternating current service includes at least an incoming hot line and a neutral line, but usually includes an incoming hot line, an incoming neutral line and a safety ground line. The surge protector has an optional input transformer and a series connected transformer with input connection to the input transformer secondary winding, and connected in series to a non-linear surge suppression circuit, and therefore has a gross output connection to the non-linear surge suppression circuit, and a low impedance input to the secondary winding of the series connected transformer from the non-linear surge suppression circuit, and has a surge cancelled hot line output connection. The input transformer embodiments are particularly useful in single phase applications.
