Modular electrical system

Abstract

An electrical system is disclosed having modular components which quickly assemble to create common lighting and general utility electrical circuits. All wiring is completed in the electrical box prior to installing the electrical devices such as switches and receptacles, thereby eliminating the need for extra length wires in the electrical boxes and the timely, cumbersome wiring practices associated with conventional residential electrical circuits. The electrical devices plug into the prewired electrical box, thereby providing quick and easy removal and replacement of the device in the event of failure. The common residential lighting and general utility circuits are automatically configured by simply selecting the proper electrical components. A dedicated earth ground is automatically carried to each electrical component with no effort on the part of the installer, thereby providing safer electrical circuits. The cables have a specific exterior profile to insure proper connection with the electrical boxes, thereby assuring proper configuration of the electrical circuits. The electrical system also eliminates the need for wire nuts. The modular electrical components include the following: a wallbox (1), a receptacle module (2), a ganging module (3), a 2-way switch module (4), a 3-way switch module (5), a 4-way switch module (6), a dimmer switch module (7), a fan-control switch module (8), a timer switch module (9), a GFCI-receptacle module (10), a 240-volt module (11), junction box (12), a light box (13), a 2-wire jumper (14), a 4-wire jumper (15), a wallbox jumper (16), a 3-conductor cable (17), a 4-conductor cable (18), and a 5-conductor cable (19).

Description

TECHNICAL FIELD

The present invention relates to the field of electrical components and more particularly to those electrical components which constitute common residential electrical circuits.

BACKGROUND ART

Conventional residential electrical circuits consist of components such as electrical receptacles, various types of light switches, electrical boxes, and electrical cables. These conventional components require time-consuming, cumbersome wiring practices. The electrical devices such as receptacles and switches must be wired prior to inserting them into their respective electrical box. This requires that the wires be of extra length to facilitate this wiring practice. This excess wire must then be stuffed into the electrical box as the electrical device is installed. These conventional electrical circuits often require the use of wire nuts to connect several wires together in the electrical boxes. These wires must also be of extra length to facilitate wiring and then stuffed into the electrical box as well.

These inherent characteristics of the conventional electrical circuits result in timely electrical installations with electrical boxes that are often over-stuffed with excess wire. The process of stuffing the wires and the electrical device into the electrical box results in the wires exerting a pulling force on their points of termination, creating the possibility of wires coming loose from the electrical device or the wire nuts. This contributes to faulty circuits and potential fire hazards.

Because of these cumbersome characteristics of the conventional electrical circuits, good wiring practices such as connecting a dedicated earth ground to each electrical component is often neglected. This also contributes to a potential fire hazard as well as a risk of electrical shock to people who use these circuits.

DISCLOSURE OF INVENTION

It is thus a principal object of this invention to provide an electrical system which utilizes modular electrical components in which the wire conductors of the electrical cables are terminated in the electrical boxes prior to the electrical devices such as receptacles, switches, and light fixtures being installed; thereby eliminating the need for the extra length wires and the cumbersome wiring practices associated with conventional residential electrical circuits.

Another object of the present invention is to provide an electrical system which utilizes modular components which assemble quickly and easily in a specific manner so as to self-configure the common residential lighting and general utility circuits by simply selecting the proper components.

It is a further object of this invention to provide an electrical system which self-distributes a dedicated earth ground to each electrical component with little or no effort on the part of the installer, thereby eliminating negligence in this wiring practice and reducing potential fire hazards and risk of electrical shock to users of these circuits.

A still further object of this invention is to provide an electrical system which utilizes modular electrical components in which the replaceable components such as the receptacles and switches simply plug into the prewired electrical box, thereby permitting easy removal and replacement.

Another object of this invention is to provide an electrical system which does not utilize wire nuts. A still further object is to provide an electrical system which is conducive to electrical circuit expansions and modifications after the initial installation is complete.

These and other objects will become apparent hereinafter.
