Abstract

See full text

Circuitry is provided in a device to automatically change the relative position of the electrical lines which enter the device upon detection of a miswired condition. More specifically, the circuitry allows the device to function normally even if an installer accidentally inverts (i.e., flips or reverses) the wiring connections when attaching connectors to a communication/power line of the device. In this manner, the installer does not need to rewire the lines.
