An electrical connection assembly includes an electrical box including a housing having an internal surface defining an internal volume of the housing. An electrical connector is positioned outside the internal volume of the housing and fixed to the housing with a fastener. The housing includes an aperture having an opening defining an insertion path extending from a location external to the housing along a frame of the electrical connector to a location within the internal volume of the housing. The assembly includes a disc mechanically secured to the housing relative to the opening to obstruct the insertion path. A retainer and a bushing including a membrane for the electrical connector as well as methods of making an electrical connector are also provided.

A mounting guide for placing a gang box on a wall structure in a predetermined location includes an elongate substantially planar vertical frame assembly with a longitudinal axis through a vertical body having a top, middle, and bottom portion. The middle portion is formed by an upper and lower lateral wall that extends parallelly from the vertical frame assembly. A laterally extendable box member may be mounted within the middle portion of the frame assembly designed to move laterally away from the vertical body as upper and lower screw members securing the box member are axially rotated. A gang box member may be mounted on a surface of the extendable box or directly to the frame. One or more hoop or clip assemblies are disposed on the frame assembly to secure at least one wire. One or more holes are disposed through the frame assembly for fasteners to surfaces.

An adjustable mounting lug for an electrical box that diminishes the degree of play of the adjustable mounting lug relative to at least an orientation of a front face of the electrical box. Sidewalls of the adjustable mounting lug can include a first portion comprising a first segment, and a second portion comprising a first inclined side, an intermediate curved side, and a second inclined side. The second portion can be configured accommodate the adjustable mounting lug having a relatively large height while maintaining at least a minimum length of a bottom wall of the adjustable mounting lug that is supported by a support louvre of the electrical box. The second portion also provides the sidewalls of the larger adjustable mounting lug with a configuration that can prevent the adjustable mounting lug from interfering with at least fittings in the box that can be associated with relatively large knockout openings.

Various components and subcomponents of a pluggable modular system for electrical junction boxes are described herein. In various embodiments, a jbox interface chassis is configured to be wired and fastened within an electrical junction box to provide a hot-swappable pluggable interface between the wires in the electrical junction box and each of a plurality of hot-swappable pluggable modular devices. The jbox interface chassis may include a front pluggable interface configured to electrically mate with a corresponding rear pluggable interface on a casing of each pluggable modular device. As an example, the jbox interface chassis may include a plurality of slots or holes to receive a corresponding plurality of blades or pins on the casing of each pluggable modular device. Additionally, device adapters are described herein to convert a wide variety of legacy electrical devices into pluggable modular devices.

Disclosed is a fireproof airtight electrical box. The disclosed fireproof airtight electrical box includes a metal gang box to which is attached a sealing mechanism which will allow the gang box device to form at least a hermetic, preferably air-tight, seal within a larger structure, while at the same time being suitable for use within such a structure because of the stiffness, strength, and at least fire resistant qualities.

The present disclosure relates to electrical box assemblies and universal stabilizing brackets that can be used to stabilize electrical boxes attached to different size wall studs. The electrical box assemblies include an electrical box and a stabilizing bracket. Each stabilizing brackets includes a base, a front stop, a rear stop and one or more rear stop segments. The front and rear stops and the rear stop segments include a face member that extends substantially perpendicularly relative to the base. One or more notches are positioned at a junction between each rear stop to facilitate the breaking away of rear stop segments to modify the length of the stabilizing bracket.

A mud ring assembly for supporting an electrical device including a base member configured to be coupled to a junction box having a first corner and a second corner. The base member has a perimeter configured to extend around the first corner and not reach the second corner so that the base member is not positioned above the second corner. The mud ring assembly also includes a movable member configured to support the electrical device. The movable member is pivotably connected to the base member and pivotable relative to the base member between a closed position in which a back of the electrical device is enclosed in the junction box and an open position permitting access to the back of the electrical device. The movable member is couplable at a second portion of the junction box to selectively secure the movable member in the closed position.

A modular electrical control system includes a switch module, having at least an on state and an off state, configured to draw power from an AC power source and to control power delivery to at least one external load, the switch module including a detector that determines whether a neutral wire is connected to the switch module, and a removable user interface module configured to connect to the switch module and receive power from the switch module, wherein the switch module delivers a first amount of power to the user interface module when the detector determines that the neutral wire is connected to the switch module, and delivers a second amount of power to the user interface module lower than the first amount of power when the detector determines that the neutral wire is not connected to the switch module.

A flexible electrical receptacle system and method for installation is provided. The system includes at least two support bars affixed parallel to one another between two wall support members. A central bar is positioned between the two support bars and configured to move along a length of the parallel support bars. An electrical receptacle affixed to the central bar and configured to move along a length of the central bar.

A bracket system for mounting an electrical box and other components can include a mounting bracket configured to be removably secured to a support bar or a threaded rod. The mounting bracket can include a plurality of spring arms that can be manually moved towards each other to insert locking profiles of the spring arms into one or more mounting openings of the electrical box. Once the locking profiles are inserted, the spring arms can be released so that they spring resiliently apart from each other and secure the locking profiles against removal from mounting openings.
