Abstract:
An electrical wiring system, in which wires from a mains voltage (normally 115 volts to 600 volts) source of supply, and wires from an extra-low voltage (normally 30 volts or less) source of supply, are routed within walls, and in particular within walls of stud and wallboard construction, within ceiling spaces or through joist spaces of a building, such as a home or an office, for the purpose of controlling the electrical current supplied to electrical devices such as receptacles, lights and heaters, so that said mains voltage wires enter an electrical device enclosure, said electrical device enclosure being of a type to which a device such as a receptacle or a light fixture may be attached, said electrical device enclosure also having a plate which covers a large opening in one wall of said electrical device enclosure, said plate being removable from within said electrical device enclosure, and so that said extra-low voltage wires are available for connection to a controlling device, said controlling device having controlling connections, controlled connections and said controlling device being installable through the open front of said electrical device enclosure, then through said large opening in one wall of said electrical device enclosure so that with said controlling device attached to said electrical device enclosure a physical barrier is present between said mains voltage wires and said extra-low voltage wires, said extra-low voltage wires being accessible when said removable plate is removed or when said controlling device is removed from within said electrical device enclosure.
