A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The second resin body includes a pair of end edge portions. The pair of end edge portions extend in inclined directions that are inclined with respect to the sliding direction, such that a gap between the pair of end edge portions in a width direction gradually decreases toward one side of the sliding direction, the width direction being orthogonal to the sliding direction and extending along the outer surface. The first resin body includes a pair of facing surfaces spaced apart in the width direction and facing each other.

A novel busbar, suitable for low-power applications, features a u-shaped extension having a male terminal that fits into and establishes electrical connection with a standard female terminal. The housing of an electrical box including the busbar is modified to receive the female terminal in such a way that Ingress Protection ratings of IP67 and IP69K are maintained within the electrical box. The busbar is not riveted to a thicker busbar terminating with a stud and lug nut, as in legacy configurations, thus being simpler and cheaper to manufacture. The female terminal, once connected to the busbar, is removable by inserting a tool into a dedicated opening within the housing.

A protective hood for outdoor electrical outlets or receptacles has an angled top surface, two side panels, and an angled bottom surface having an aperture. In one variant of the protective hood, the aperture in is configured to receive power cords for connection to an electrical outlet over which the protective hood has been mounted, such as an existing electrical outlet installed on a building wall or a power pedestal. In another variant of the protective hood, the aperture in the angled bottom surface is configured to allow an electrical outlet to be installed directly therein, but with the protective hood still being mountable over an electrical outlet on a building wall or power pedestal instead of having an electrical outlet installed in the aperture.

Prefabricated electrical modules and system along with fabrication and construction methods are provided. The prefabricated electrical system includes multiple framed, prefabricated electrical modules of one or more types. The prefabricated electrical module disclosed may comprise one or more of a main service electrical module, a low-voltage module, a switch component module, and a receptacle component module. The casing of the interior components of the modules is weatherproofed and/or weatherized. Each of the modules includes a module exterior frame that accommodates the specialized elements of that particular module. Methods for fabrication of the modules are disclosed. Construction methods for installing the assemblies are also disclosed.

A conductive device includes a housing, a glass insulator, and a conductor. The housing comprises an opening. The glass insulator is located within the opening, wherein a seal is formed between the housing and the glass insulator. The conductor is located at least partially within the glass insulator and comprises at least one of conductive ceramic, cemented carbide, and cermet. A seal is formed between the glass insulator and the conductor.

A lid for a junction box includes a structure which is arranged to connect and seal an opening of the junction box. The sealing prevents the ingress of foreign matter such as liquids or solid particles into the junction box. The structure is, or includes, a window that is transparent to visible light to enable visual inspection inside the junction box. The lid includes a cover that is opaque to UV or UV-IR wavelengths and is arranged to selectively: (a) shield the transparent portion of the structure from direct impingement of a wavelength or a band of wavelengths to prevent transmission of the wavelength or a band of wavelengths into the junction box; and (b) enable visual inspection inside of the junction box through the transparent portion.

A modular stackable enclosure system is disclosed herein. The system includes a base structure including a cavity that includes a component mounting surface. The base structure also includes a plurality of modular ports configured to provide openings to the cavity. The base structure also includes a plurality of accessory mount interfaces, configured to receive a plurality of corresponding toolless-attachable accessory mounts. The system also includes a plurality of port plates, each configured to fit into a port of the plurality of modular ports. The system also includes a plurality of port plate attachments, each configured to fit into a corresponding port plate. The system also includes a cover, configurable to attach to the base structure, such that the cover is movable to cover or expose the cavity.

A seal assembly/adaptor for sealing a weather protection boot to an irregular shaped interface port such as a port having externally facing threads. The seal assembly/adaptor includes a seal subassembly comprising a compliant ring having plurality of arcuate segments defining an opening for accepting the interface port. Further, the seal assembly/adaptor includes at least one retainer operative to retain the seal subassembly such that, upon assembly, an axial force imparted by a connector coupling device effects radial deformation of at least one of the flexible segments into the irregular surface of the interface port to effect a seal between the irregular surface and the retainer.

Embodiments of an integrated piping conduit in accordance with aspects of the present invention include a push-to-connect fitting integrated with an adaptor device and associated methods that facilitate the re-use of push fittings without damage to the fitting elements or the pipe, while also facilitating connection to boxes such as electrical boxes in a manner that meets requirements and saves time for professionals dealing with the otherwise challenging management of multiple wires, cables and/or connections. Embodiments can incorporate an integrated release pusher and locking mechanism that allows for quick locking and unlocking of piping elements within a fitting. Embodiments can also include an adaptor having integrated head and body portions, and an ear member extending at least partially radially outwardly and at least partially axially outwardly from the outer surface of the body portion.

A curb and cap junction box assembly protecting joined electrical conductors includes a curb member with a planar flashing and central housing extending upwardly from the flashing, forming an enclosed space. The central housing has top and bottom openings. A plate, secured over the bottom opening has a knockout section and a mounting pan for circuit boards. A cap member has a planar top and peripheral edge extending downward. The cap member reversibly fastens over the top opening of the central housing. The junction box assembly is secured to a structure by the flashing and receives an electrical conductor from the structure through the knockout aperture in the plate member. The electrical conductor extends through the top opening of the central housing and under the downward extending peripheral edge of the cap member and outside the junction box assembly. The junction box provides enclosure for high voltage applications.
