Mounted on the upright panel 20 are side panels 21 and 22, which extend from the top of the panel housing 15 to a point intermediate the ends of the side panels 16 and 17. Detachably mounted on the side panels 21 and 22 is a removable front panel 25. The front panel 25 and the lower portion of the upright panel 20 form the front of the panel housing 15. A top panel 26 seats on the front panel 25, the side panels 21 and 22, the upright panel 20, the side panels 16 and 17, and the upper rear panel 19. A bottom panel 27 is fixed to the side panels 21 and 22 and to the upright panel 20. Generally, the lower portions of the upright member 20, the side panels 16 and 17, the lower rear panel 18 are installed in the ground with the ground level as shown in FIG. 1.
Conductors from a source of electrical power, such as public utility electrical lines, are received by the opening 29 (FIG. 4) in the panel housing 15 and are connected to suitable upright line conductors 30 and 31 (FIG. 5). The line conductors 30 and 31 pass through a suitable insulator, such as a sponge wall 32. The sponge wall serves to absorb any moisture collecting in the vicinity thereof. The line conductors 30 and 31 are connected at the upper ends thereof to suitable line connectors or terminals 35 and 36 (FIGS. 5 and 6), which are mounted on suitable insulators 37 and 38. The insulators 37 and 38 are in the form of phenolic bases which are fixed to the upright panel 20. Suitable openings 30 and 40 are formed in the upright panel 20 for the reception of the line connectors 35 and 36.
In the preferred embodiment, the line connectors 35 and 36 are spring clip receptacles with jaws and are tin-plated copper. The terminal portions of the connectors 35 and 36 are conventional receptacles for receiving plugs and the like secured in place by screws.
Formed in the removable or detachable front panel 25 is an opening 44 (FIGS. 1 and 2), in which is seated a conventional watt-hour meter 45 (FIG. 1). The watt-hour meter 45 includes a line side and a load side. Disposed in the opening 44 is an upright support member 46 (FIG. 2). Fixed to the support member 46 are horizontally disposed, vertically spaced insulators 47 and 48. Mounted on each end of the insulator 47 and facing the meter 45 are line connectors 50 and 51 (FIG. 2). The line connectors 50 and 51 are preferably in the form of spring clip receptacles with jaws that are tin-plated copper.

Additionally, the line connectors 55 and 56 engage the line receptacles 50 and 51, respectively, for establishing electrical connections therewith. Thus, when the detachable front panel 25 is mounted on the panel housing 15, electrical connections are established from the line conductors 30 and 31, through the line receptacle connectors 35 and 36, through the stab-type line connectors 55 and 56 and to the line receptacle connectors 50 and 51.
When the front panel 25 is mounted on the panel housing 15 and the meter 45 is installed, then electrical connections are established through the meter 45 from the line receptacle connectors 50 and 51 to the load receptacle connectors 52 and 53. The meter 45 includes stab-like connectors received respectively by the spring clip receptacles 50-53, when installed. Mounted on each end of the insulator 48 and facing the upright panel 20 are suitable terminals 60 and 61 (FIG. 7). For convenience, the load terminals 60 and 61 are in the form of stab-type load connectors, which are made of copper.
Mounted on the detachable front panel 25 is a suitable circuit breaker 65 (FIGS. 2 and 7). A suitable opening 66 is formed in the removable front panel 25 for seating the circuit breaker 65. It is conventional and also within the purview of the present invention to mount suitable power fittings on the detachable front panel 25. Should it be desired that the meter power distributing apparatus 10 have a different ampere rating or should it be desired to include power fittings or different power fittings, then the front panel 25 is removed and replaced with a similar preselected front panel.
Suitable conductors 70 and 71 interconnect the terminals 60 and 61 with the input side of the circuit breaker 65. A suitable rain cover 73 is pivotally mounted on the front panel 25. When in the downward position (FIG. 1), the rain cover 73 protects the circuit breaker 65 from the elements. When in the raised position (FIG. 2), the cover 73 exposes the circuit breaker 65.
According to the present invention, load connectors 75 and 76 (FIG. 7) are mounted on a suitable insulator 77, such as a phenolic insulator. In turn, the insulator is mounted on the removable front panel 25. The load connectors 75 and 76 confront the upright panel 20. Conductors 80 and 81 establish electrical connections from the output side of the circuit breaker 65 to the terminals of the load connectors 75 and 76. In the preferred embodiment, the load connectors 75 and 76 are in the form of stab-type connectors made of tin-plated copper.
Mating with the load connectors 75 and 76 are load connectors 82 and 83 (FIG. 6) which are mounted on an insulator base 84. The insulator base 84 is preferably made of phenolic material.
