An extendable electrical box comprises an electrical box having two open ends to an internal box space having a first depth. The electrical box comprises a mounting structure attached to at least one wall of the electrical box. The mounting structure is configured to mount the electrical box to a vertical wall structure such that the open end faces substantially parallel to the vertical wall structure. At least two extendable first rings each continuously surround one of the two open ends of the electrical box. The at least two extendable first rings are each slidably coupled with the electrical box via the sliding mechanical cooperation of one or more guides with one or more tracks, such that sliding either of the at least two extendable first rings in relation to the open ends of the electrical box expands the electrical box from the first depth to a larger second depth.

A negative terminal is connected to the first negative bus bar in a first of the plurality of configurations and a second of the plurality of configurations, and the negative terminal is connected to the second negative bus bar in a third of the plurality of configurations and a fourth of the plurality of configurations, a positive terminal is connected to the first positive bus bar in the first of the plurality of configurations and the second of the plurality of configurations, and the positive terminal is connected to the second positive bus bar in the third of the plurality of configurations and the fourth of the plurality of configurations.

Provided is a resin molded article which makes it possible to prevent breakage of a resin and collar loss at joint sections. A resin molded article (1) is formed by resin injection, and comprises a main body (2) and a joint section (3) integrally formed at an outer wall surface (4) of the main body (2) and having a cylindrical section (11) configured to insert therethrough the joint member for attaching the main body (2) to a mating member (6). The joint section (3) is formed to be asymmetric about a perpendicular plane (19) which passes through the central axis (18) of the cylindrical sections (11), and is perpendicular to the outer wall surface (4) of the main body (2).

An improved mounting block has a base plate portion and a face plate portion. Base plate portion has an outer surface extending outward from a mounting surface and is selectively attachable to the face plate portion. One of the face plate portion and the base plate portion has a plurality of snap fit teeth formed thereon, and the other has a plurality of snap fit receivers, configured to selectively receive the snap fit teeth. Face plate portion may include flange flex grooves formed in an attachment flange, allowing walls to deflect independently from corners, such that the flange flex grooves allow the attachment flange to flex outward from the outer surface. Base plate portion may include alignment ribs extending outward from the outer surface, such that the flange flex grooves formed in the attachment flange interface with the alignment ribs formed on the base plate portion.

An electrical connection box includes: a casing that has an opening portion open upwardly, a recessed portion recessed downwardly from an upper edge portion of a side wall; and a slidable cover configured to close the recessed portion. A first thin portion is formed at a side edge portion of the recessed portion of the casing. A second thin portion is formed on the slidable cover. The first thin portion and the second thin portion overlap each other when the slidable cover is fitted into the recessed portion. The first thin portion is includes a chamfered portion where a boundary between an opening edge portion of the first thin portion and the side edge portion is chamfered. A contact portion is configured to be brought into contact with the chamfered portion.

The present disclosure discloses an electrical receptacle assembly. The electrical receptacle assembly comprises a housing with a first compartment and a second compartment with at least one third opening for receiving power supply cables. The first compartment has a second opening for receiving a switch knob, defined with central axis. A base of the second compartment fitted with a switch assembly in the housing. The switch assembly defines a spindle which is required to align axially with the central axis of the slot of the switch knob. A first and a second switch assembly mounting locations on the base mounts the switch assembly. The first mounting location is used when the power supply cables are positioned to enter the receptacle from operatively below the receptacle and the second mounting location is used when the power supply cables are positioned to enter the receptacle from operatively above the receptacle.

A recessed, deployable ceiling box assembly comprising a ceiling frame-mounting member and a ceiling box member, a support member for securing the ceiling frame-mounting member to a ceiling structural member and one or more connector members for attaching the ceiling box member to the ceiling frame-mounting member. The ceiling box member is deployable from a retracted position, where the ceiling box member is retained within the ceiling frame-mounting member at or above the height of the ceiling, to a deployed position, where the ceiling box member hangs by the connector member below the height of the ceiling. A door may be used to cover the contents of the deployable ceiling box assembly.

An electrical junction box can include a case, a substrate connector, and a substrate. The substrate is temporarily fixed and soldered to the substrate connector. The substrate connector and the substrate are stored in the case. The substrate connector includes a pair of shaft-shaped temporary fixing protrusions. Each of the temporary fixing protrusions includes a positioning shaft that positions the substrate and a temporary fixing shaft that prevents the temporary fixing protrusions from coming loose from the substrate. The temporary fixing protrusions can be fitted into fitting holes in the substrate.

One aspect is an electrical junction with wireless controller configured for attachment in a building structure. The junction includes a junction body having surfaces defining an opening. A junction device is coupled to the opening of the junction body and a wireless controller is coupled to the junction body. An external conductor routs voltage from a voltage source in the building structure into the junction body. The wireless controller is electrically coupled between the external conductor and the junction device and is mechanically coupled to the junction body behind a surface of the building structure.

A double-single stainless steel electrical junction box is configured to receive two single covers. A center bridge spans between the top and bottom surfaces to define a first and a second cover plate-mounting aperture adjacent each lateral side of the bridge. The interior compartment of the junction box is common to both of the first and second cover plate-mounting apertures. Electrical conduit hubs can be disposed above the top surface and below the bottom surface of the junction box to allow electrical wiring to reach the interior compartment.
