Individual cables can exit the tray at any point, simplifying the wiring installation and reducing the labour cost for installing new cables. Power cables may have fittings in the tray to maintain clearance between the conductors, but small control wiring is often installed without any intentional spacing between cables.

Cable management is particularly important in powered equipment which must move large distances while tethered to a power source and control cabling. There are several common methods of cable management. With a suspended sliding coil, the cables are coiled like a spring, with each loop of the coil attached to a sliding shoe on a track.
A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals or power from one device to the other. Long-distance communication takes place over undersea communication cables. Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable.
If the subscriber's building does not have a cable service drop, the cable company will install one. The standard cable used in the U.S. is RG-6, which has a 75 ohm impedance, and connects with a type F connector. The cable company's portion of the wiring usually ends at a distribution box on the building exterior, and built-in cable wiring in ...
