A wiring device and method that control an amount of power delivered to a load, which maintain function even if a line connection and a load connection are reverse wired. Designed circuitry comprising steering diodes in both a line and a load wire direct a power source to an AC/DC power supply. The wiring device comprises a housing, a line terminal nominally designated for receiving electrical power from a power source, a load terminal nominally designated to feed electricity to a load, a neutral terminal, a line wire electrically connected to the line terminal, a load wire electrically connected to the load terminal, and a means for controlling an amount of power delivered to the load. Embodiments of the present invention include automated universal lighting controls, dimers, timers, and wired lighting devices.
