Abstract
An electrical power distribution system for efficiently installing electrical lights, devices, and power outlets to selectively energize or de-energize an electrical load in a building or structure. The electrical power distribution system comprises a control module installed in a building comprising the controlled output that is selectively energized by controlling a latching relay connected to an AC supply source and a load to be energized. Some embodiments further comprise an electronic switch in parallel with a relay. In addition, other embodiments include an electronic switch in parallel with a relay controlled by the same control signal to energize a load, where the electronic switch is energized before the contacts of the relay close and the electronic switch is de-energized after the contacts of the relay open. In an exemplary embodiment the load may be controlled and its ON/OFF status may be known at a distance of at least one mile with a pair of wires, AWG #24 or smaller diameter.
