Abstract: Mounting devices for electrical fixtures have a hollow housing having an entrance end and an opposing exit end, exterior threading configured to engage a building material, and interior threads, and having a faceplate as a head of a threaded stem. The threaded stem has a bore therethrough in the longitudinal direction and is threadingly engaged with the interior threads of the hollow housing. The mounting devices can have a housing defining a cavity. The housing has a first end with interior threads and an opposing second end having a through hole and exterior threads, an insulating lining in the cavity, a strain relief collar seated in the cavity and operatively connected to a wire or cable for an electrical fixture, a wiring connector, and a cap with a faceplate having a threaded stem that is removably threaded to the interior threads of the hollow housing.

Abstract: Methods for molding an electrical socket into concrete during the concrete pouring process are disclosed. The method includes mounting an electrical junction box assembly to a concrete form. The electrical junction box has a closure plate that defines a first through hole configured to receive an electrical switch or electrical outlet, a secondary plate mounted directly to the closure plate, and a removable blank seated in the second through hole and having a bolt extending through the removable blank and protruding forward a distance sufficient to be received in and protrude from the hole in the concrete form. The secondary plate has a forward protruding flange defining a second through hole aligned with the first through hole. Then, the method includes pouring concrete into the concrete form, thereby surrounding the electrical junction box with concrete, and after the concrete is set, removing the concrete form and the removable blank.

Abstract: Systems for mounting an electrical junction box in a concrete structure and methods of making concrete structures with such electrical junction boxes molded therein are disclosed. The system includes a secondary plate configured to be mounted to a closure plate of an electrical junction box, a removable blank seated in the second through hole, and a bolt extending through the removable blank. The removable blank protrudes forward a distance sufficient to mount to a concrete form. The secondary plate has a forward protruding flange defining a second through hole aligned with the first through hole and a rear surface of the secondary plate comprises a recess therein that extends from the second through hole in a radial outward direction and the bolt terminates with a foot and the recess of the secondary plate is shaped to receive the foot to define a latched position for the removable blank.

Abstract: Wiring systems for class 2 or class 3 devices include a structural support defined by a first conductive layer opposite a second conductive layer with an insulating layer juxtaposed therebetween, and an electrical jack fastener that has a head of conductive material electrically insulated from a fastener portion of conductive material by an insulator insert and is insertable into the structural support at any position along the first conductive surface to engage the fastener portion with the second conductive layer and the head with the first conductive layer. The first and second conductive layers are configured to connect to a class 2 or a class 3 power supply to define a circuit, and the head of the electrical jack fastener has a first terminal configured to connect to a first wire and the fastener portion has a second terminal configured to connect to a second wire.
