A ground level primary electrical distribution system deploys terrain mounted or essentially terrain flush pipes that protect suppress ignition from fires that may occur if components fail within the pipes. The pipes can be deployed in remote and rugged terrain where overhead power lines poses fire risks from wind damage and it is impractical and disruptive to bury the electricity conducting cable or deployed along roadways or field at ground level or essentially flush with the ground to avoid excavation yet avoid the use of overhead power lines that can be subject to damage from high wind. The pipes can follow the terrain between junctions over rigid segments formed by a plurality of end-to-end coupled enclosures, while the conductors are protected within jacketing or flow through flexible insulating and isolating conduits within the more rigid pipes.

One or more techniques and/or systems are disclosed for a wiring protection device. The wiring protection device can comprise a first shell and second shell that are operably coupled with each other in a rotational engagement. The orientation, shape and hollow body of the respective shells allow for wiring to be guided through the device to a wiring coupler disposed in the second shell. Disposing the wiring and coupler(s) inside the body of the device can provide protection from contaminants during use and assembly, such as dirt, water, grease, and paint.

A conduit nipple grounding bushing to connect between two electrical enclosures or an electrical enclosure and a conduit body, comprising a body having a first portion and a second portion forming a hollow cylindrical interior for the passage of conductors therethrough, the body having a first opening at a first end of the body and a second opening at a second end of the body, the first portion having an outer surface with one or more mounting pads along a circumferential area, each of said one or more mounting pads configured for receipt of a grounding lug, and an end surface dimensioned to contact an electrical box about a knockout hole thereof, and wherein the second portion has exterior threads configured to pass through a knockout hole of an electrical box and dimensioned for receipt of a locknut if the conduit nipple grounding bushing is connected between two electrical boxes or for threaded engagement with a threaded hub of a conduit body if the conduit nipple grounding bushing is connected between an electrical box and a conduit body; and a grounding lug dimensioned for securement to one of the mounting pads by a screw, wherein the mounting pad includes a threaded bore for receipt of said screw.

An electric metallic tube (EMT) conduit apparatus includes an electric metallic tube (EMT) conduit, a first insulated connector housing attached to a first end of the electric metallic tube (EMT) conduit and a second insulated connector housing attached to a first end of the electric metallic tube (EMT) conduit. The first insulated connector housing includes a plurality of electrically conductive male pins and the second insulated connector housing includes a plurality of electrically conductive female pins. A plurality of conductors within the electric metallic tube (EMT) conduit include a first end attached to one of the male pins of the first insulated connector housing, and a second end attached to one of the female pins of the second insulated connector housing.

A conduit outlet assembly for a rigid metal conduit raceway of an electrical system is provided. A conduit outlet assembly includes a gasket, a gripping ring, and a condulet assembly. The gasket is sized to circumscribe an outer surface of a rigid metal conduit of the rigid metal conduit raceway. The gripping ring is sized to circumscribe the outer surface of the rigid metal conduit. The condulet assembly is sized to receive the rigid metal conduit, and includes an adapter and a condulet. The adapter includes a compression section and a coupling section, wherein the compression section is sized to receive the rigid metal conduit with the gasket and the gripping ring disposed thereon. The condulet is sized to receive the coupling section of the adapter.

Disclosed is a wire protector for use in a wire protection system. The wire protector includes a first tubular member and a second member fittable within the first tubular member. The second member includes flexible or bendable fingers which expand after being passed through the first tubular member to lock the second member with respect to the first tubular member. A plurality of wire protectors are placed into studs during construction of a building. Electrical wires are passed through the plurality of wire protectors.

A sheathing member includes: a plurality of tubular units into each of which a wiring material having conductivity is inserted; and a connecting unit configured to connect respective open ends of the plurality of tubular units with each other, in which the tubular units respectively include lap portions in which the open ends to be connected overlap each other along a diameter direction, and the connecting unit includes a projection that is provided in the lap portion of one of the tubular units to be connected and projects along the diameter direction, and a groove unit that is provided in the lap portion of the other of the tubular units to be connected, includes a first groove extending from the open end along an axis direction and a second groove extending from an axially-extended end of the first groove along a circumference direction, and has the projection passed therethrough.

The invention relates to a connection system consisting of a first connection element and a second connection element and a linking element which is provided in order to link two devices. The first connection element and the second connection element are preferably formed as plug-in connectors and the linking element is provided in the form of a cable-sheath assembly which carries cables and lines. The advantageous teaching according to the invention allows connection systems of this type to be designed such that the cables and lines provided in the linking element and a sheath surrounding same are not mechanically overloaded, even under heavy mechanical loads, preferably tensile loads.

A ninety degree electrical fitting for connecting electrical cable to an electrical box. The ninety degree electrical fitting includes a connector body with a leading end and a trailing end, a snap ring connected to the leading end, and a clip member connected to the trailing end. A leading flange and a box engagement flange on the leading end of the connector body define a means for retaining the snap ring on the connector body. A clip member connected to the connector body provides a means for securing an electrical cable to the trailing end of the fitting. Internal walls on the connector body define an internal passageway having a wide turn radius, to enable wiring leads from an electrical cable to pass easily through the internal passageway of the connector body. The ninety degree snap fit electrical fitting provides good electrical continuity between the outer sheath of an electrical cable, the electrical box, and the fitting.

A cable manager includes one or more cable manager units. Each cable manager unit includes a pair of side cable guides, each comprised of a plurality of finger-like projections extending forwardly from a support column. At least one of the pair of support columns has a socket arranged at a side thereof. Each cable manager unit further includes a separate midsection member capable of insertion into the socket for interconnecting the pair of side cable guides.
