Each built-in offset preferably has two side walls extending from the body and a mounting arm between the side walls. Each mounting arm includes a plurality of clamp mounting apertures used to attach a conduit clamp to the mounting arm. Each of the plurality of built-in hanger tabs are preferably bendable relative to the body. Box and conduit support kits that includes a body and a plurality of hanger clips are also provided.

An exemplary cabling system includes a plurality of containers. A first container of the plurality of containers defines a first plurality of openings. The system includes a plurality of bolts with a first bolt operable to insert into the first plurality of openings. The first bolt defines a first conduit operable to receive a first cable of a plurality of cables. An exemplary telecommunications central office includes a container with a plurality of walls defining an interior of the container and an exterior of the container, an opening, a vault entrance, and a plurality of cable runways. An exemplary method for arranging cables includes cutting a wall of a first and second container to create a first and second opening, inserting flanges of bolts into the openings, receiving with a pipe the flanges, and routing a cable through the first and second opening into an interior of the second container.

A pivotable junction box and driver housing unit includes a junction box having a junction box cavity, and a driver housing having a driver housing cavity to contain a light fixture driver. The junction box and the driver housing are attached to each other. The junction box and the driver housing are rotatable with respect to each other.

An electrical cable assembly, comprising a first electrical circuit further comprising a first plurality of insulated conductors longitudinally disposed to one another, wherein the first plurality of insulated conductors are cabled together in a bundle. The electrical cable assembly further comprises a second electrical circuit longitudinally disposed to the first electrical circuit, the second electrical circuit comprising a second plurality of insulated conductors longitudinally disposed to one another and cabled together in a bundle and a nonmetallic jacket surrounding the second plurality of insulated conductors and wherein the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit. The electrical cable assembly further comprises a flexible interlocking metallic armor encasing the first and second electrical circuits.

Provided is an adaptable fire-resistant housing for a light fixture, comprising: a. a junction box made from steel, the junction box having an opening on a bottom configured to receive the light fixture; and b. an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.

Disclosed herein is a modular structural and electrical building system. The system includes first and second structural support members. In use, the second end of the first structural support member is adjacent the first end of the second structural support member. The system further includes at least one conductor bar secured to each of the structural members. In addition, the system utilizes conductor bar connectors for maintaining electrical connectivity from one conductor bar to the next on the same structural support member and a power drop connector for connecting electrical power carried by the conductor bar to various pieces of equipment. In addition, a jump cable provides a bridge for electrical power from the conductor bar on the first structural member to the conductor bar secured to an adjacent structural member.

A modular utility room a mobile enclosure is positionable adjacent to an information technology (IT) enclosure of a modular data center (MDC). One of a first and second equipment cabinet is selected for installing in the mobile enclosure. Each equipment cabinet contains functional equipment having a lower electrical coupling component that are connectable to substrate-installed conduits below the mobile enclosure and an upper electrical coupling component that connect to and support rack-based information handling systems (IHSs) in the IT enclosure. An interface panel is received in an interface panel opening in the mobile enclosure correspond to the selected equipment cabinet and will not receive the other equipment cabinet. The interface panel positions the lower electrical coupling over a conduit opening in alignment with a defined location relative to the mobile enclosure for alignment with the substrate-installed conduits at a deployed location of the mobile utility room.

Provided is an adaptable fire-resistant housing for a light fixture, comprising a junction box made from steel. the junction box having an opening on a bottom configured to receive the light fixture; and an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.
