A conduit box useful for mounting on an industrial size AC induction motor in a hazardous environment. The conduit box includes a cover and housing, a gasket seal between the cover and housing, and an internal partition wall. The conduit box is made of a cross-linked polymer matrix with a glass fiber content of about 26% by weight, in which the material has thermosetting dimensional stability and formed from a composition of polyesters and vinyl ester. The walls of the conduit box are tapered and the conduit box otherwise composed and constructed to meet requirements of the hazardous environment.

A canopy assembly for a light fixture includes a mounting bracket configured to be positioned over a junction box and directly mounted to a support surface. A canopy cover is connected to the mounting bracket. The canopy cover includes a plurality of conduit openings. One or more cover inserts are configured to be selectively positioned in the conduit openings. One or more conduit inserts are configured to be selectively positioned in the conduit openings. The canopy cover is configured to extend over the mounting bracket and the junction box.

Provided are a casing for an electrical apparatus for housing an electrical apparatus includes: a casing body having an opening; a cover body that includes a flat plate-like cover portion having a rectangular shape for covering the opening, and outer side surface cover portions that are continuous to respective sides of the flat plate-like cover portion and cover outer side surfaces of the casing body; and first ribs that are provided on the outer side surfaces of the casing body covered by the outer side surface cover portions and extend along the respective sides, and a power control apparatus that includes the casing for an electrical apparatus and the electrical apparatus housed in the casing for an electrical apparatus.

In accordance with 37 C.F.R. § 1.121(b)(2)(i), please replace the abstract of the specification as filed with the following paragraph:

A method of making an electrically conductive and weatherproof enclosure includes mixing and melting an electrically conductive material, a latex rubber material, and a polycarbonate material to produce a weatherproof material mixture, blending carbon black with polyethylene to produce an electrically conductive additive, positioning an injection mold of the enclosure in fluid communication with an exit end of a heating barrel, injecting the weatherproof material mixture into an entry end of the heating barrel, introducing the electrically conductive additive through a lateral port of the heating barrel proximate to the exit end to partially mix with the weatherproof material mixture to produce an injection mixture, and injecting the injection mixture into the injection mold to produce the electrically conductive and weatherproof enclosure.

An electric junction box unit includes an electric junction box, a bracket holding the electric junction box, and a holder assembled to the bracket. The bracket includes a plate-shaped back face portion facing the electric junction box, a plurality of holding portions which are erected from the back face portion along an assembly direction of the electric junction box and which hold the electric junction box, and an engaging recessed portion engaging with the holder in a state where the back face portion is sandwiched between the electric junction box and the holder. The engaging recessed portion includes a first recessed portion receiving a first engaging piece of the holder along a direction intersecting the assembly direction, and a second recessed portion receiving a second engaging piece of the holder along the assembly direction.

A wall-mounted enclosure assembly utilizes insertable door mounting components that allow the enclosure door to be easily mounted to the enclosure main housing without the use of tools and in a manner that easily sets the door installation depth to match the depth of the surrounding drywall. After the enclosure main housing is mounted in the wall, insertable mounting components that serve as hinges and latches for the door are inserted into slots formed on the vertical sides of the main housing. The insertable mounting components can be inserted to a desired depth but cannot be withdrawn from the slots until a release tab is pressed. The installation depth of the hinges and latches is correctly set to match the thickness of the drywall merely by inserting the insertable mounting components until a stopping surface on the components abuts the drywall.

A closed system for placing installations, especially electrical ones

The closed system for placing installations is formed by interconnected chamber modules (1, 2, 3, 4, 5) of a rectangular top view. In the connection area, the adjacent modules (1,2,3,4,5) are provided with lowered edges which overlap, and in the overlap area vertical through holes (9) are provided for module (1,2,3,4,5) fasteners. The fasteners consist of screws (11) and nuts (12). The lowered edges are provided in the horizontal abutting surfaces with horizontal coaxial passages (10). These passages (10) connect the chambers (6) of adjacent modules (1,2,3,4,5) and cables pass through them. The passages (10) are provided with a sealing grommet (13) which is made of a resilient material. The chamber modules (1,2,3,4,5) consist of two caps (7, 8) attached to each other.

A wall-mounted assembly may include one or more host devices which receive line voltage and generate low voltage power on one or more contacts for powering one or more modular devices. The one or more modular devices may be installed adjacent to the host device and may share a faceplate with the host device, such as a standard decorator faceplate. The modular devices may receive power from the host device via a power bus between the host device and the one or more modular devices. Further, the power bus may include a communication bus for communication between the host device and the modular devices. The faceplate may be a smart faceplate, which may include circuitry, such as a battery backup, occupancy sensing, a charging dock for a mobile phone, etc.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A rectangular or square mud ring assembly includes a base member, a raised member, a telescoping member and a plurality of drive members. The base member has a flange and a rectangular or square opening through the flange. The raised member extends from the base member and follows the rectangular or square opening in the flange to form a rectangular or square raised wall. The raised member has a plurality of mounting tabs extending from the raised wall toward the opening in the raised member. The telescoping member is positioned within the raised member opening and is movable relative to the raised member between a retracted position and an extended position. The telescoping member has a rectangular or square wall, an opening and a plurality of mounting tabs extending from the rectangular or square wall toward the opening in the telescoping member. The rectangular or square wall of the telescoping member includes a plurality of protective members. Each protective member is positioned in proximity to one of a plurality of mounting tab pairs. In this configuration, one of the plurality of drive members is operatively coupled to the mounting tabs of one of the mounting tab pairs, such that rotation of the drive members causes the telescoping member to move between the retracted position and the extended position.
