Electrical wires are used in homes as well as in large scale, complex projects such as industries or factories. They are used to transmit electrical signals from one place to another. For different purposes of diverse magnitude, different electrical wires are required.
The wiring is done with the help of different cable laying equipment and tools that are easily available at any gadget store. Different wires require different equipment. Types of electrical wires include:
1. NM cables (Romex):
Named after the popular brand “Romex”; these wires come in different gauges with their particular amps (amperage). These wires are used in interiors, and are only suitable in a moisture free, dry environment.
2. UF cables:
UF stand or Underground Feeder. These types of wires contain insulated, hot and neutral wires, with a ground wire as well. As the name suggests, these types of wires are used for undergrounds projects and in wet locations. These are non-metallic cables which are also used outdoors, for example, supplying electricity to outdoor light sources such as lamp posts,street lights etc.
3. THWN and THHN wires:
These wires are Thermoplastic, Heat resistant, can be used in Wet locations, and are Nylon coated, hence are known as THWN. HH stands for High Heat resistant. These are two very common types of wires which are used in basements, garages or any unfinished areas. Also used in the wiring related to hot water heaters at home; the wires are used in conduits which are mostly used in areas under construction.
4. Phone and data wire:
Used to connect landlines and the internet; these are also called low voltage wires. Usually there are 4 or 8 wires in the telephone cable, which provides better strength and data transmission.
These are the various kinds of electrical wires used at indoors or outdoors, manufactured for different purposes.
