Abstract

An electrical housing apparatus has an electrically non-conductive enclosure with side and end walls. One of the end walls has an opening to receive an electrical conduit and the other walls are un-perforated. An electrically conductive frame is mounted inside the enclosure, the frame being arranged to support electrical devices is a specific vertical orientation and provide ground bonding between the conduits and electrical devices in the housing. Mounting brackets at opposite ends of the frame have openings either of which can be aligned with the end wall opening when the frame is placed in the enclosure, depending on the orientation of the enclosure: the end wall with the opening can be at the top to accommodate a top conduit connection or at the bottom to accommodate a bottom conduit connection. A water-resistant cover closes the front of the box, the cover and frame being arranged to have a single orientation regardless of which enclosure orientation is used.

Claims

1. A housing for containing electrical apparatus and for accommodating connection of said apparatus to electrical conductors passing from outside to inside the housing comprising the combination of

an enclosure made of an electrically non-conductive material, said enclosure having

one wall having a connection opening therethrough dimensioned to be attached to means for containing electrical conductors,

a plurality of substantially un-perforated walls including side and back walls, and

means including edges of said walls defining an open side opposite said back wall;

a frame dimensioned to be received in said enclosure, said frame being made of an electrically conductive material and having

a central portion, and

substantially identical top and bottom end members, each said end member having an opening therethrough dimensioned to be attached to said means for containing electrical conductors;

means for mounting said enclosure on a support surface with said back wall adjacent said surface and with said wall having said connection opening through said wall thereof being selectively oriented either at the top or at the bottom of said enclosure; and

means for fixedly mounting said frame in said enclosure with one of said top and bottom end members adjacent to and aligned with said connection opening, whereby said enclosure is mountable in different positions for different cable connections with said frame in a single orientation and without making additional openings through said enclosure walls.

2. A housing according to claim 1 and further comprising means on said frame for supporting electrical apparatus.

3. A housing according to claim 1 and further comprising cover means for closing said open side.

4. A housing according to claim 3 wherein said cover means includes means for supporting electrical apparatus thereon.

5. A housing according to claim 4 and further comprising a lid hingedly supported on said cover means for covering exposed portions of said cover means and apparatus supported thereon.

6. A housing according to claim 4 wherein said cover means includes means defining a recess and means for supporting an electrical receptacle having a front face exposed in said recess, said housing further comprising a lid and hinge sub-assembly removably attached to said cover means, said lid being movable between open and closed positions in which said recess is open and covered, respectively.

7. A housing according to claim 6 wherein said sub-assembly comprises a mounting bracket having a first hinge portion, a second hinge portion formed on said lid, a hinge pin extending through said first and second hinge portions and a spring around said hinge pin for urging said lid toward said closed position.

8. A housing according to claim 1 wherein said means for containing electrical conductors comprises a metal conduit, said electrically conductive frame forming a ground connection between said conduit and said electrical apparatus in said housing.

9. A housing according to claim 1 and further comprising a cover dimensioned to close said open side and having a top edge and a bottom edge, and means for attaching said cover to said enclosure with said top edge up when said enclosure is mounted on said support surface with said connection opening either up or down.

10. A housing according to claim 9 wherein said cover includes means defining a recess in said cover and means for supporting an electrical device in said recess, said housing further comprising a door hingedly attached to said cover and movable to a closed position for selectively covering said recess and said electrical device.

11. A housing according to claim 10 wherein said cover further includes means defining a protruding short wall surrounding said recess, said short wall forming a peak at the edge thereof closest to said top edge of said cover and pointing toward said top edge to deflect water.

12. A housing according to claim 11 wherein, in said closed position, said door extends across said recess and substantially lies in a plane containing distal edges of said short wall, said door including edges extending toward said cover and remaining spaced from said cover and said short wall in said closed position and substantially surrounding said short wall to inhibit entry of water into said recess.

14. A housing according to claim 1 wherein said enclosure has a centerline which extends vertically when said enclosure is mounted in either of said positions, and wherein said connection opening is laterally displaced from said centerline.

15. A housing according to claim 14 wherein said electrical apparatus is mounted substantially centered on said centerline whereby water entering said enclosure and following wires entering said connection opening is led away from said electrical apparatus.

13. A housing according to claim wherein said frame includes first and second arms extending from said central portion toward said open side of said enclosure for supporting an electrical device.

16. A housing for containing electrical apparatus and for accommodating connection of said apparatus to electrical conductors passing from outside to inside the housing comprising the combination of

an enclosure made of an electrically non-conductive material, said enclosure having

one wall having a connection opening therethrough dimensioned to be attached to means for containing electrical conductors,

a plurality of additional walls including a back wall, and

means including edges of said walls defining an open side

a frame dimensioned to be received in said enclosure, said frame being made of an electrically conductive material and having

a central portion, and

substantially identical top and bottom end members, each said end member having an opening therethrough dimensioned to be attached to said means for containing electrical conductors;

means for mounting said enclosure on a support surface with said back wall adjacent said surface and with said wall having said connection opening through said wall thereof being selectively oriented either at the top or at the bottom of said enclosure; and

means for fixedly mounting said frame in said enclosure with one of said top and bottom end members adjacent to and aligned with said connection opening, whereby said enclosure is mountable in different positions for different cable connections with said frame in a single orientation and without making additional openings through said top or bottom of said enclosure.
