The configuration of an electrical junction box is simplified and made compact. Provided is an electrical junction box for a vehicle, including a housing that accommodates a high-voltage circuit for high voltages and a low-voltage circuit for low voltages, the electrical junction box including a connection portion for connection to the outside, the connection portion being provided on the housing, wherein the connection portion has both a high-voltage terminal connected to the high-voltage circuit and a low-voltage terminal connected to the low-voltage circuit.

Systems, methods, and articles of manufacture for modular junction boxes. Some modular junction boxes may, for example, comprise integral mating elements that are secured in position by mounting of one or more adapters, connectors, or fittings.

An electrical box for accommodating at least one duplex electrical outlet including a first side, a second side having a mount opening therein. The electrical box also includes a mounting tube. The mounting tube is mountable to the mount opening. The mounting tube further includes first tubular member having a first length, and a second member fittable within the first tubular member. The second member further includes a tubular main body including a tubular portion fittable within the first tubular member, and a first end including a stop. The first end and stop engage the mount opening in the second side.

The present disclosure provides descriptions of electrical box assemblies for supporting heavy fixtures, such as ceiling fans, and facilitating electrical connections to the fixtures. The electrical box assembly includes an electrical box that allows a connection between the box and electrical conduits and a connection, e.g., a weatherproof connection, with a housing of the fixture. The box has an open front face to house electrical connections between the fixture and wires supplying electrical power to the box via the conduits. The box has a bottom wall and an open front face. A reinforcement member fits within the electrical box and includes a panel shaped to conform to at least a portion of the bottom wall and one or more standoffs extending toward the open front face of the box. When the reinforcement member is positioned within the box, mounting holes in the bottom wall of the box and reinforcement member are aligned to allow the box to be attached to a building structure.

A wall box may provide adjustable support for a control device, such as a keypad, to allow for level alignment of the control device when mounted to the wall box. The wall box may have an adjustable support frame to which the control device may be mounted. When the control device is mounted to the support frame of the wall box, the support frame may be rotated to adjust the alignment of the control device. In addition, the wall box may comprise one or more projections configured to be received in respective detents in notched surfaces of the control device to allow for adjustment of the alignment of the control device. Further, the wall box may have a modular assembly and may be constructed from a central portion and two side portions at the time of installation of the wall box.

A mud ring assembly includes base member, raised member, telescoping member and plurality of drive members. The base member has a flange and an opening through the flange. The raised member extends from the base member and follows the opening in the flange to form a 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 wall, an opening and a plurality of mounting tabs extending from the wall toward the opening in the telescoping member. Rotation of the drive members causes the telescoping member to move between the retracted position and the extended position.

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.

A system for occupancy detection and prediction is disclosed. The system may include a modular control unit configured to control power to at least one load device, which may include a device control assembly configured to be removably coupled to a backplate. The device control assembly may include an occupancy sensor configured to detect a current occupancy state of a detection zone. The device control assembly may be configured to determine occupancy routines based on historical occupancy states of the detection zone and to predict future occupancy states. The device control assembly may be configured to control the power to the at least one load device based on the predicted future occupancy states.

Provided is a junction box with a screw-free rotary flip cover used for a lighting device. The junction box comprises a junction box main body, a first cover body and a second cover body. The junction box main body is provided with a first accommodating space and a second accommodating space. The first cover body of the junction box is fixedly connected with the junction box main body and covers the first accommodating space. The second cover body is rotatably connected with the first cover body. When the second cover body rotates relative to the first cover body, the second cover body can cover or open the second accommodating space. Electrical components are mounted in the first accommodating space and the second accommodating space.
