Abstract

#$%^&*AU2023248140B220250626.pdf##### 11 Abstract A recessed electrical junction box designed to house electrical apparatus within walls and ceilings consists of a container with an integrated flange that interfaces with the container’s rim. The container and flange are one piece, often plastic injection- moulded, and create a flush surface with the interior wall when installed. The flange can be sealed to the wall or a waterproof barrier, forming a watertight seal meeting codes and standards related to internal wet area waterproofing. Installation may involve inserting the container through a wall opening, allowing the flange to interface with a waterproof membrane to prevent water ingress. Holes for electrical cabling can be made and sealed, or the container may have destructible tabs for creating these holes. The junction box may also include angled sides to allow for stacking and prevention of water collection. The container may have interior side projections which serve as attachment holes for the electrical apparatus and through which electrical wiring may be run. 20 23 24 81 40 1 2 O ct 2 02 3 Abstract A recessed electrical junction box designed to house electrical apparatus within walls 2023248140 12 Oct 2023 and ceilings consists of a container with an integrated flange that interfaces with the container's rim.
