Abstract
Abstract A pre-wired electrical circuit box for structures and/or distributive wiring, comprising a circuit box made of nonconducting material, adapted to be mounted to the structure or appendage of a building. A plurality of electrical circuit boards of insulating material, assembled coaxially in parallel, spaced relation and locked in angular relation to each other. A plurality of electrical fastenings or connectors attached to each of the circuit boards at their periphery in selected, individual, angularly-spaced pattern. The fastenings on each board are connected to each other in selected manner. The spaced boards are of lesser diameter than the container box, and are inserted into the box, coaxially therewith, and fastened in fixed angular position. A plurality of small diameter openings in the wall of the circuit box are provided so that ends of wires can be cleared of insulation and inserted through appropriate openings opposite each one of the fastenings on the boards. Thus the bare electrical wire can be inserted through the opening into the corresponding fastening or connector opposite that opening. The pattern of electrical connection between the plurality of fastenings on each of the boards is based upon the particular use for which the circuit box is designed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
228 words
A prewired electrical circuit box comprising: (a) a circuit box made of thin walled non-conducting material, having a base of lateral dimension D and a circumferential wall of height H, and means to mount said circuit box to a structure; (b) a plurality of electrical circuit boards of shape similar to that of said box, and of dimension less than D, assembled co-axially, in parallel spaced relation, and locked in angular relation to each other, (c) a plurality of electrical fastenings attached to each of said circuit boards at their periphery, in selected individual angularly-spaced pattern, said fastenings on each board connected together electrically in selected patterns which are different on at least two boards. (d) means to mount said assembly of circuit boards in said circuit box in a fixed angular position; (e) a plurality of small diameter openings in the wall of said circuit box, each of said openings positioned opposite one of said fastenings on said boards, so that a bare electrical wire of selected diameter can be inserted through an opening into the corresponding fastening opposite that opening; and (f) means to attach and detach each wire to and from said fastening in which it is inserted; whereby a plurality of electrical wires can be inserted into selected ones of said plurality of openings, and be connected to each other in a preselected manner.
Claim 2
Dependent Claim
228 words
A prewired electrical circuit box comprising: (a) a circuit box made of thin walled non-conducting material, having a base of lateral dimension D and a circumferential wall of height H, and means to mount said circuit box to a structure; (b) a plurality of electrical circuit boards of shape similar to that of said box, and of dimension less than D, assembled co-axially, in parallel spaced relation, and locked in angular relation to each other, (c) a plurality of electrical fastenings attached to each of said circuit boards at their periphery, in selected individual angularly-spaced pattern, said fastenings on each board connected together electrically in selected patterns which are different on at least two boards. (d) means to mount said assembly of circuit boards in said circuit box in a fixed angular position; (e) a plurality of small diameter openings in the wall of said circuit box, each of said openings positioned opposite one of said fastenings on said boards, so that a bare electrical wire of selected diameter can be inserted through an opening into the corresponding fastening opposite that opening; and (f) means to attach and detach each wire to and from said fastening in which it is inserted; whereby a plurality of electrical wires can be inserted into selected ones of said plurality of openings, and be connected to each other in a preselected manner.
Claim 3
Dependent Claim
31 words

Claim 10
Dependent Claim
69 words
The circuit box as in claim 1 in which said box is a junction box, and in which: (a) a first board has at least two separate input fastenings, each one connected to at least two output fastenings; (b) a second board having at least one separate input fastening connected to at least two output fastenings; and (c) a third board having a plurality of fastenings all connected together.
Claim 11
Dependent Claim
90 words
