Terms for Electical Wiring and Cable If you are considering home or office restorations or renovations, the electrical wiring system will likely have to be updated. It is a good idea to look for wiring in bulk from wholesale suppliers if you have to rewire an entire building. The following list of terms might help you to understand the various types of cables and wiring systems you are likely to encounter:
Copper Wire: The most widely used conductor wire for power generation, power transmission, telecommunications and circuitry. Copper has a very high level of electrical conductivity; higher than any other non precious metal.
Coaxial Cable: A type of cable commonly used to transmit television high frequency signals and connect different types of video equipment.
Ethernet Cables: Also known as Unshielded Twisted Pair cables (UTP). These cables are used for the connection of audio/video systems, telephones and digital networks. These cables are also commonly known as Category 5E Cables, and are made up of a network of copper wires surrounded by flexible thermoplastic sheathing.
NM-B Cable: Also known as Non-Metallic cable, the NM-B cable is the common type of cable used in residential electrical wiring. It has a flexible PVC jacket over the internal networking of wiring.
UF Cable: Also known as Underground Feeder Cable, UF cable, while similar to NM-B cable, has a tougher shield, and is used in outdoor wiring applications due to the fact that it is resistant to wetness. The internal wiring is encased in solid thermoplastic rather than flexible PVC.
AC Cable: AC or Armored cable is a type of cable that has metal sheathing, due to the fact that metal sheathing acts as a grounding conductor. AC cable is no longer widely used in residential wiring applications, but is still found in older buildings.
