A conduit nipple grounding bushing to connect between two electrical enclosures or an electrical enclosure and a conduit body, comprising a body having a first portion and a second portion forming a hollow cylindrical interior for the passage of conductors therethrough, the body having a first opening at a first end of the body and a second opening at a second end of the body, the first portion having an outer surface with one or more mounting pads along a circumferential area, each of said one or more mounting pads configured for receipt of a grounding lug, and an end surface dimensioned to contact an electrical box about a knockout hole thereof, and wherein the second portion has exterior threads configured to pass through a knockout hole of an electrical box and dimensioned for receipt of a locknut if the conduit nipple grounding bushing is connected between two electrical boxes or for threaded engagement with a threaded hub of a conduit body if the conduit nipple grounding bushing is connected between an electrical box and a conduit body; and a grounding lug dimensioned for securement to one of the mounting pads by a screw, wherein the mounting pad includes a threaded bore for receipt of said screw.

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 The insertable mounting components can be inserted to a desired depth but cannot be withdrawn from the slots until a release tab is pressed.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 lighting system has a plurality of central-control devices and a plurality of groups of local light-control devices. The central-control devices are electrically connected in a first daisy-chain form. Each group of local light-control devices are electrically connected in a second daisy-chain form. Each group of local light-control devices are connected to one of the plurality of central-control devices.

The present invention discloses a foldable electrical junction box for lighting apparatus comprising a base board formed by a metal plate, and four side boards disposed peripherally around the base board; the four side boards are rotationally mounted on the base board which is rectangular in shape; the four side boards comprise two long side boards and two short side boards; the long side boards and the short side boards are rotationally mounted on long sides and short sides of the base board respectively; at an open state, the two long side boards and the two short side boards are rotated outwards to form a box with the base board which is open on top and has a hollow cavity; at a folded state, the two long side boards and the two short side boards are rotated inwards to fold on the base board to form a flat rectangular body.

Disclosed is a wire protector for use in a wire protection system. The wire protector includes a first tubular member and a second member fittable within the first tubular member. The second member includes flexible or bendable fingers which expand after being passed through the first tubular member to lock the second member with respect to the first tubular member. A plurality of wire protectors are placed into studs during construction of a building. Electrical wires are passed through the plurality of wire protectors.

A punch set for use with a punch tool to punch material from a wall of an electrical box. The punch set has a punch with a cutting section, and a die defining a cavity that is configured to receive the cutting section. The cutting section may have an annular or circular portion and a plurality of keyway forming portions each extending radially from the annular or circular portion. The cutting section of the punch may be insertable into the cavity of the die in a single orientation. The die may have a protrusion receivable within a recess of the punch when the cutting section is received in the cavity. One of the die or punch may have an extension that is receivable in a single orientation within an opening in the other of the die or punch.

An electrical junction box includes a housing, a bus bar including a first flat plate portion having a first bolt hole, a plate having a window portion, a plate-shaped terminal including a second flat plate portion having a second bolt hole and configured to be assembled to the plate so as to close the window portion, and a fastening member configured to be inserted into the first bolt hole and the second bolt hole to fasten and fix the bus bar and the terminal together to the housing. The housing and the plate are configured such that the first flat plate portion and the second fiat plate portion are stacked to each other and the first bolt hole and the second bolt hole are coaxially arranged by assembling the plate to the housing to which the bus bar is assembled.

The present invention provides a remote-operated intelligent microcomputer light switch that can fully replace conventional switches, which can execute the on/off function of general wall switches, and different remote settings and operations can be performed through a smart device. The switch comprises an ornamental panel; an operation core; a button area providing touch switch function, combined with a LED indicator light to display status, an embedded battery supplies power for persistent operation, and contacts identical with general wall switches; a control pedestal, embedded with a control circuit abutting connecting terminals on the operation core to obtain control signal, and the high and low tension circuits are completely isolated to avoid the risk of electric shock. There are foolproof locking holes in the upper and lower parts of the framework of the control pedestal, which can fix the operation core in a fixed direction to avoid vertical reversal. The operation core engages with the control pedestal, and then they are integrated with the ornamental panel, so as to achieve touch function and remote operation with a smart device, and to implement technicalized life of smart home to upgrade the quality of life.
