Abstract
Abstract An electric power outlet box is used to connect either an underground or overhead supply line led into the box, and by either underground or overhead outlet conduits from the box it services the establishment of an adjacent power consumer such as a unit in a mobile home park. Top and bottom walls of the upstanding, rectangular box are each formed with a pair of actual or potential apertures, members of each pair within the box being separated by a generally vertical channel-forming baffle, each baffle spaced laterally from the adjacent side-wall of the box and inwardly terminating at a central area adjacent terminals provided for connection of the inlet and outlet lines. A circuit breaker and jaws for mounting an electric meter are part of the circuit thus formed. Incoming and outgoing conduits placed along opposite sides of a baffle are thus physically isolated in event of sparking or flame-out in the box, and thus need not be carried through opposite walls to meet safety requirements. Such box may be mounted on the side of a hollow post, through which post an underground supply conduit can be brought into the box through a knock-out aperture in the rear face in place of use of one of the other four apertures. As many of the latter as are not used to carry conduits at a particular installation, remain sealed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
208 words
An electric power outlet box, comprising walls defining an enclosure including a base surface and at least two side-walls projecting generally upright therefrom, each of which side-walls are formed with a pair of aperture means providing passage to the interior of said enclosure For an electric conduit, said enclosure having mounted therein circuit-forming elements including a circuit breaker and means for attaching an electric supply conduit which may be carried in through any one of said aperture means, terminal means for connection of outlet conduits which may be carried out through any one of said aperture means, meter connection means for detachably coupling an electric meter in position to measure current flowing in said outlet conduits, and baffle means comprising a pair of channel-forming members upstanding from said base surface, each member extending inward from a side-wall intermediate a pair of said aperture means to form adjacent open-face channels terminating adjacent said attaching means, whereby a supply conduit and an outlet conduit carried through said adjacent aperture means may be physically separated within said enclosure by location in respective channels on opposite sides of said member and any and all of said conduits may be brought through said respective apertures from either underground or overhpad positions external thereto.
Claim 2
Dependent Claim
208 words
An electric power outlet box, comprising walls defining an enclosure including a base surface and at least two side-walls projecting generally upright therefrom, each of which side-walls are formed with a pair of aperture means providing passage to the interior of said enclosure For an electric conduit, said enclosure having mounted therein circuit-forming elements including a circuit breaker and means for attaching an electric supply conduit which may be carried in through any one of said aperture means, terminal means for connection of outlet conduits which may be carried out through any one of said aperture means, meter connection means for detachably coupling an electric meter in position to measure current flowing in said outlet conduits, and baffle means comprising a pair of channel-forming members upstanding from said base surface, each member extending inward from a side-wall intermediate a pair of said aperture means to form adjacent open-face channels terminating adjacent said attaching means, whereby a supply conduit and an outlet conduit carried through said adjacent aperture means may be physically separated within said enclosure by location in respective channels on opposite sides of said member and any and all of said conduits may be brought through said respective apertures from either underground or overhpad positions external thereto.
Claim 3
Dependent Claim
36 words
The electric power outlet box of claim 1 wherein said two side-walls form opposite sides of a vertically disposable enclosure, with said channel-forming members each spaced laterally inward from a respective upright wall of said enclosure.
Claim 4
Dependent Claim
31 words
The electric power outlet box of claim 2 which is additionally characterized by aperture means in said base surface adapted to receive a supply conduit for connection to said attaching means.
Claim 5
Dependent Claim
45 words
The electric power outlet box of claim 3 which is mounted on a hollow post which is traversed lengthwise by an underground supply conduit which is then carried through the aperture means of said base surface and secured to said attaching means within the enclosure.
Claim 6
Dependent Claim
123 words
An electric power outlet box comprising a generally rectangular enclosure formed by a back wall, peripheral walls upstanding therefrom and a front closure, said enclosure having a central attachment area therein containing means for attachment to meter and circuit breaker units, the interior of said enclosure being characterized by a pair of baffle means upstanding from said back wall and extending inward to adjacent said central attachment area from adjacent diagonally opposite corners of the enclosure, forming open-face channels along opposite sides thereof, and a pair of aperture means formed in said enclosure walls adjacent the outer end of each of said baffle means whereby separate access may be provided to each of said channels for respective electric conduits from outside said box.
Claim 7
Dependent Claim
123 words
An electric power outlet box comprising a generally rectangular enclosure formed by a back wall, peripheral walls upstanding therefrom and a front closure, said enclosure having a central attachment area therein containing means for attachment to meter and circuit breaker units, the interior of said enclosure being characterized by a pair of baffle means upstanding from said back wall and extending inward to adjacent said central attachment area from adjacent diagonally opposite corners of the enclosure, forming open-face channels along opposite sides thereof, and a pair of aperture means formed in said enclosure walls adjacent the outer end of each of said baffle means whereby separate access may be provided to each of said channels for respective electric conduits from outside said box.
