Apparatus and methods are employed to install fiber optic cables in a data center facility using one or more cable dispensing robots that dispense fiber optic cable that is pre-spooled on a cable cartridge, by programmatically unspooling the cable from the cable cartridge and paying the cable out along a potentially transverse oscillatory path (e.g. sinusoidal curve) as the robot moves down a cable tray network that is arranged adjacent and above large numbers of equipment bays. A controller accesses a database which stores the state of the cables within the cable tray network. The database further stores information regarding availability of cable cartridges of standard cable lengths, which are potentially stored within a cable cassette loading/unloading system. The controller receives instructions on where and how to spatially deploy a fiber optic interconnect cable within the tray network of the data center facility.

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.

An electrical cable assembly comprising a first electrical circuit comprising at least two insulated conductors, a second electrical circuit, and a conductive metallic armor encasing the first and second electrical circuits, wherein the conductive metallic armor provides a return ground path. The second electrical circuit comprising at least two control insulated conductors, a jacket surrounding the control insulated conductors, and a wrap surrounding the jacket which is surrounding the control insulated conductors.

The present disclosure is directed to achieve greater space efficiency. A wiring module (A) includes a first transmission line (20), and a noise shielding member (40) that has a sheet shape and is arranged along the first transmission line (20). The noise shielding member (40) has a thickness of 100 μm to 600 μm. Since the noise shielding member (40) has a sheet shape, and thus the space for arranging the noise shielding member (40) can be made smaller, it is possible to achieve greater space efficiency. Since the noise shielding member (40) has a thickness of 100 μm to 600 μm, it is possible to obtain a high noise shielding effect.

A method and apparatus for quick, safe, and easy installation of electrical fixtures in the building construction field, including connecting the fixture to a mounting mechanism for structural support and electrical service. A coupling mechanism is attached to or incorporated into the fixture. The coupling mechanism has built-in electrical leads that are designed to connect with the electrical leads on a fixture-facing interface of the mounting mechanism. Electrical leads on the coupling mechanism are connected via wire or other electrically conductive material to the electrical components in the fixture.

A recessed, deployable ceiling box assembly comprising a ceiling frame-mounting member and a ceiling box member, a support member for securing the ceiling frame-mounting member to a ceiling structural member and one or more connector members for attaching the ceiling box member to the ceiling frame-mounting member. The ceiling box member is deployable from a retracted position, where the ceiling box member is retained within the ceiling frame-mounting member at or above the height of the ceiling, to a deployed position, where the ceiling box member hangs by the connector member below the height of the ceiling. A door may be used to cover the contents of the deployable ceiling box assembly.

A support for electrical boxes can include a body plate, first and second mounting arms, and first and second side flanges. The body plate can include mounting features configured to secure an electrical box to the body plate. The first and second mounting arms can extend from the body plate and receive a threaded rod to support the body plate in a horizontal orientation. The first and second side flange extend from opposing sides of the body and include an aperture to receive a threaded rod that can support the body plate in a vertical orientation.
