Abstract
An electrical control wiring system in which mains voltage (115 volts to 600 volts) power loads in a home or in a commercial building are controlled by use of extra low voltage devices such as switches, variable resistances and microcontrollers. Wires are routed from an electrical panel and looped between special electrical device enclosures that in some respects resemble conventional electrical outlet boxes. The special electrical device enclosures are located in walls so that the front edges appear flush with the finished wall as would be the case with a conventional electrical outlet box in a finished room. The mains voltage wiring is done in the manner normally used in mains voltage wiring. Multi-conductor extra-low voltage cable such as Category 5 cable is routed from a control location and looped to the same special electrical device enclosure locations. The special electrical device enclosure has a plate, which is removable from within the special electrical device enclosure and once this plate is removed, a large opening is present in one wall of the special electrical device enclosure. The extra-low voltage wiring is accessible through the large opening in one wall of the …
