T stands for thermoplastic insulation and H for heat resistance. The second time H stands for heat resistance that goes up to 194-degrees Fahrenheit and W means it can be used in wet locations. And last but not the least N means the wire can-not be damaged by oil or gas.

• Material: The other information label provides is material type. Nowadays, most of the wires are available in the copper material and hence come with “CU” symbol.

• Voltage rating: You can also check maximum voltage it can carry on the label. • Gauge: In addition to the voltage rating, material type and application, you can also find out wire size by checking gauges on its label.

UF cable: It is just like NM-B Cable but is used in underground and damp areas. Although, UF cables appear just like NM-B Cables but they come embedded with thermoplastic. UF cables are provided in the market in a variety of gauges. Coaxial cables: Also known as coax, these metallic cables are used in transmission of signals and during making connection of video equipment.

Category 5e cables: Also known as CAT-5e, these are the twisted-pair cables that are used to connect phones and computer networks. These are also called Ethernet cables and consist of 4 pairs of copper wires.

Armored cable: These cables are usually utilized during new residential construction but are widely found in older homes too. Also known as BX, armored cables are available in the market at high cost and can be used only for indoor purposes.

Metal-clad cable: Just like the above one, these cables are also rated for indoor use and can’t be used for outdoor purposes.
