Abstract
An AC power line protection device includes a resistive element connected at one end to a hot power conductor and at another end to either a breaker coil operatively associated with a set of interrupting contacts or to a gate or base for a switch element. When AC power is miswired to the load terminals, the device trips the contacts due to the presence of the resistive element. The device does not work properly until AC power is connected to the line terminals, at which time the resistive element clears itself from the circuit. An indicator lamp lights when the device is in the tripped condition and turns off when the device is reset. If the device is miswired after having been wired properly, i.e., the resistive element has cleared, the indicator lamp does not light when the device is tripped, and so provides a supplemental indication of miswiring.
