US Patent 10498053 Electrical wiring junction box

The electrical wiring junction box comprises an insulated base, a plurality of wiring apertures, a plurality of bar apertures, a plurality of conductive bars, and a plurality of clamp screws. The insulated base may comprise a plurality of tiers at different vertical heights. Each of the plurality of tiers may be associated with an electrical attribute. A first conductor of a first circuit may be electrically coupled to a second conductor of a second circuit by connecting the conductors to the same bar at one tier. An individual conductor may be connected to the individual bar by placing the stripped end of the individual conductor into an individual wiring aperture selected from the plurality of wiring apertures and then tightening an individual clamp screw at the individual wiring aperture where the individual conductor is inserted.
