Panel wire support brackets

1. A panel wire support bracket for supporting a plurality of insulated electrical wires, comprising:

a preformed end cap including a stud face;

a preformed support bar formed with a plurality of holes for locating and slidably supporting a plurality of insulated electrical wires each passing through one of the holes, and formed with a front surface, a back surface, and a plurality of guide walls that extend downward from the plurality of holes so that the front surface and the back surface conform to and mate with the preformed end cap and overlap the plurality of guide walls;

wherein:

the support bar and the preformed end cap are molded as a single element;

the end cap may be fastened to a building with the stud face flush against the building.

2. The support bracket of claim 1 , further comprising:

a protective plate extending along the support bar to help protect the plurality of insulated electrical wires.

3. The support bracket of claim 1 , wherein the end cap is formed with predefined nail holes.

4. The support bracket of claim 1 , wherein:

the preformed end cap defines an end width and an end vertical centerline between the end width; and

the support bar is approximately centered along the vertical centerline.

5. The support bracket of claim 4 , wherein the support bar defines a bar width that is less than the end width.

6. A panel wire support bracket for supporting a plurality of insulated electrical wires, comprising:

a preformed end cap including a stud face;

a preformed support bar formed with a front surface, a back surface, and a plurality of holes for locating and slidably supporting a plurality of insulated electrical wires each passing through one of the holes, with the support bar and the preformed end cap connected together; and

a plurality of guide walls that extend downward from the plurality of holes so that the front surface and the back surface conform to and mate with the preformed end cap and overlap the plurality of guide walls.

7. The support bracket of claim 6 , further comprising a bottom section with a plurality of bottom guide walls that extend upward from the bottom section, and telescopingly encompass the guide walls of the preformed support bar.

8. The support bracket of claim 6 , wherein:

the retaining flange is formed from at least two discontinuous walls leaving unobstructed vertical passage between the discontinuous walls; and

the support bar is formed with an open cutout in the support end;

so that an electrical wire may be fished through unobstructed vertical passage, even when the support end is mated with the retaining flange.

9. The support bracket of claim 6 , further comprising a protective plate held on the preformed support bar to protect wires passing through one or more of the plurality of holes.

10. A panel wire support bracket for supporting a plurality of insulated electrical wires, comprising:

a preformed end cap including a stud face;

a preformed support bar formed with a plurality of holes for locating and slidably supporting a plurality of insulated electrical wires each passing through one of the holes, and formed with a front surface, a back surface, and a plurality of top guide walls that extend downward from the plurality of holes so that the front surface and the back surface may conform to and mate with the preformed end cap and overlap the plurality of guide walls;

wherein:

the support bar and the preformed end cap are connected together;

at least one of the plurality of holes is sized to have a long axis defining a length with approximately parallel flat walls, and a short axis perpendicular to the long axis defining a width, with semicircular end walls connecting the flat walls across the width;

the length of the long axis when measured from distal points of the semicircular end walls is approximately twice the width of the short axis; and

the width is less than 0.28-inches.

11. The support bracket of claim 10 , further comprising:

a protective plate held between the end cap and the support bar to protect wires passing through one or more of the holes.

12. The support bracket of claim 10 , wherein the end cap is formed with predefined nail holes.

13. A panel wire support bracket, comprising:

a preformed end cap defining an end width and a cap vertical centerline between the end width; and

a preformed support bar extending from the end cap;

wherein:

the support bar is approximately centered along the vertical centerline;

the support bar defines a bar width such that there is at least a 2:1 relative difference between the end width and the bar width;

the support bar and the end cap are connected together by a proximal bar portion so that the support bar is held in place when the end cap is attached to an underlying structure;

the support bar is formed with a front surface, a back surface, and a plurality of wire passageways; and

a plurality of guide walls extend downward from the plurality of wire passageways so that the front surface and the back surface conform to and mate with the preformed end cap and overlap the plurality of guide walls.

14. The support bracket of claim 13 , wherein the support bar is formed from two pieces including a top section and a bottom section.

15. The support bracket of claim 13 , wherein:

the preformed end cap includes a stud face and a support face, and a retaining flange extending outwardly from the support face;

the proximal bar portion is sized to conform to and mate with the retaining flange of the end cap.

16. The support bracket of claim 15 , wherein:

the retaining flange is formed from at least two discontinuous walls leaving unobstructed vertical passage between the discontinuous walls; and

the support bar is formed with an open cutout in the support end;

so that an electrical wire may be fished through unobstructed vertical passage, even when the support end is mated with the retaining flange.

17. The support bracket of claim 13 , further comprising a protective plate held on the preformed support bar to protect one or more of the plurality of wire passageways.
