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.

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.

Improvements in a bracket is disclosed for mounting an electrical box onto a mounting bar. An electrical box can be preinstalled onto the bracket and clamped onto the mounting bar using wings. Wings on the bracket are biased towards a closed position and can be moved to an open position by squeezing tabs on said wings. A fastener hole on the central body of the bracket allows for installers to preinstall an electrical box onto said bracket. Thus, an installer can secure the bracket and electrical box using a screw and adjust the position of the bracket on the mounting bar.

A vapor barrier cover for installation to an electrical box in the rough-in phase of construction. The vapor barrier cover includes a flange with an opening having an inner periphery and a body extending from the inner periphery of the flange. The body includes walls extending to a front edge. A front wall extending from the front edge includes a front opening and a rearward extending wing. Installation of the vapor barrier cover enables inspection and testing for air-tightness around the periphery of the electrical box prior to the final phase of construction and without the need for a gasket.

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 mounting bracket for mounting a junction box to a stud of a wall includes a face plate having opposite left and right edge margins. The face plate attaches to the junction box. A stud mounting flange is coupled to one of the left and right edge margin of the face plate and engages the stud. At least one clamping flange is coupled to the stud mounting flange and is configured to engage the stud. The at least one clamping flange is resiliently deflectable and applies a force to the stud to hold the mounting bracket on the stud when the mounting bracket is mounted to the stud.

An electrical box assembly includes an electrical box structure including an interior defined by a plurality of walls with an aperture formed through one of the walls for providing access to the interior of the box structure. An aperture cover extends over the aperture. The aperture is formed from a resiliently flexible material and includes a slit forming feature for prescribing a location of a slit for selectively providing access to the interior of the electrical box structure. The resiliency of the aperture cover urges the aperture cover to a closed position of the slit to minimize air passage through the aperture cover.

Disclosed are various embodiments for a trim cover for electrical junction boxes. In one aspect a trim cover kit for installing electrical junction boxes to framing of a wall is disclosed. The kit includes an electrical junction box, an electrical outlet or switch with wiring and terminal screws, and a trim cover having an interior surface, an exterior surface, a distal border capable of covering the opening in the wall structure, and a proximal border with an opening for the electrical outlet. The trim cover further includes interior flashing on the sides of the proximal border to secure the trim cover within a wall structure, as well as to provide a thermal barrier, and to protect against contact with the terminal screws. The trim cover further includes one or more alignment fastener points and/or retaining screw guides for fastening the trim cover to the electrical junction box.

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 wall-mounted enclosure having a standard forward-facing opening but also having an expanded enclosure behind the opening. The opening allows the use of conventional prior art components (such as cover plates). The expanded enclosure allows a more generous bend radius for the creation of a service loop in a fiber optic cable or similar component.
