Meter socket assembly
A meter socket assembly comprising a meter jaw assembly and an extended bus bar for contact with a meter blade of a watt hour meter. The meter jaw assembly further comprises a meter jaw and a jaw spring guide that are mounted together by a fastening device to the extended bus bar. The extended bus bar comprises a chamfered terminal end and cutout portion to easily accept the meter blade. The jaw spring guide overlies the meter jaw and applies a bias force inward to urge the contact face of the meter jaw toward the extended bus bar closing any insertion space and guaranteeing tight contact with the meter blade. A meter socket guide snaps on to the bus bar to maintain the alignment of meter jaw with watt-hour meter blade.
1. A meter socket assembly for an electrical meter box comprising:
an extended bus bar of generally L-shape, the bus bar having first and second ends, the first end being constructed and arranged to be coupled with a base associated with the meter box;
a meter jaw assembly with a meter jaw for securing and contacting a meter blade of a watt hour meter with the second end of the extended bus bar; and
a fastening device for mounting the meter jaw assembly to the extended bus bar,
the meter socket assembly being in combination with three additional meter socket assemblies defining two pairs of meter socket assemblies disposed in spaced relation, wherein each extended bus bar has a surface defining a cutout portion, and wherein a single meter socket guide contacts the surface defining the cutout portion of each extended bus bar to maintain spacing between the extended bus bars for ensuring alignment of each meter jaw with an associated blade of a watt-hour meter.

5. The combination of claim 1 , wherein the meter jaw assembly comprises a jaw spring guide for overlying the meter jaw.
6. The combination of claim 5 , wherein the jaw spring guide comprises at least one arm guide for securing the meter blade of the watt hour meter.
7. The combination of claim 5 , wherein the jaw spring guide provides a spring bias force to contact the meter blade with the meter jaw and the extended bus bar.
8. The combination of claim 5 , wherein the jaw spring guide comprises at least one fastening opening to mate with the fastening device.
9. The combination of claim 1 , wherein the second end of the extended bus bar has a chamfered receptacle terminal for receiving the meter blade.
10. The combination of claim 1 , wherein the extended bus bar comprises at least one fastening opening to mate with the fastening device.
11. The combination of claim 1 , in further combination with the base in the form of a base pan, the first end of the extended bus bar being coupled to the base pan via an attachment device.
12. The combination of claim 11 , wherein the attachment device is one of a screw, a rivet or a bolt.
13. A meter socket enclosure assembly comprising:
a housing comprising a plurality of walls wherein a front wall includes an opening for mounting a watt hour meter;
a base pan mounted to an inner surface of a back wall of the housing, and four meter socket assemblies mounted to the base pan, each meter socket assembly comprising:
an extended bus bar, the bus bar having first and second ends, the first end being coupled with the base pan;
a meter jaw adjacent to a surface of the second of the extended bus bar for securing and contacting a meter blade of a watt hour meter between the meter jaw and surface of the second end of the extended bus bar; and
a fastening device for mounting the meter jaw assembly to the extended bus bar,
wherein the meter socket assemblies define two pairs of meter socket assemblies disposed in spaced relation, wherein each extended bus bar has a surface defining a cutout portion, and wherein a single meter socket guide contacts the surface defining the cutout portion of each extended bus bar to maintain spacing between the extended bus bars for ensuring alignment of each meter jaw with an associated blade of a watt-hour meter.
14. The enclosure of claim 13 , wherein each meter socket assembly includes an extended bus bar having an end coupled to the base pan via an attachment device.
15. The enclosure of claim 14 , wherein the attachment device is one of a screw, a rivet or a bolt.
16. The enclosure of claim 14 , wherein each extended bus bar is of generally L-shape.
17. A method to limit heat rise in a meter socket assembly of an electrical meter box comprising the steps of:
providing four extended bus bars defining two pairs of extended bus bars, each bus bar being of generally L-shape and having first and second ends, the first end being constructed and arranged to be coupled with a base associated with the meter box; each extended bus bar having a surface defining a cutout portion,
providing a meter jaw assembly having a meter jaw adjacent to the second end of each extended bus bar;
contacting a single meter socket guide with the surface defining the cutout portion of each extended bus bar to maintain spacing between the extended bus bars for ensuring alignment of each meter jaw with an associated blade of a watt-hour meter, and
contacting a meter blade of a watt hour meter between each extended bus bar and the associated meter jaw with the bus bar acting as a heat sink transferring heat generated at the first end of the bus bar towards the second end thereof.
18. The method of claim 17 , wherein the meter jaw has a joggled bend.
19. The method of claim 17 , wherein the meter jaw has a plurality of separated fingers to contact the meter blade.
20. The method of claim 17 , wherein the meter jaw is coupled via a fastening device with the extended bus bar.
21. The method of claim 17 , wherein the meter jaw assembly comprises a jaw spring guide for overlying the meter jaw.
22. The method of claim 21 , wherein the jaw spring guide comprises at least one arm guide for securing the meter blade of the watt hour meter.
23. The method of claim 21 , wherein the jaw spring guide provides a spring bias force to contact the meter blade with the meter jaw and the extended bus bar.
24. The method of claim 21 , wherein the jaw spring guide comprises at least one fastening opening to couple with the meter jaw and the extended bus bar.
25. The method of claim 21 , wherein the extended bus bar comprises at least one fastening opening to couple with the meter jaw and the jaw spring guide.
26. The method of claim 17 , wherein the extended bus bar has a chamfered receptacle terminal for receiving the meter blade.
