Electric wires and their types

electric wires are the conductors that carry electric current from a source, typically a transformer nearby, to an outlet in your residence or company. They also have electricity in electrical devices and appliances. Electrical wires are available in various materials, enclosures, and sizes to manage a variety of electrical loads and situations. Mainly all electrical wires are constructed of copper. However, they can also be made of aluminum and other metals.

Single Conductor Wire:

Single-conductor wire is the typical type of electric wire. There are two types of stranded yarn: stranded and solid. Stranded wires are used in various essential devices, including cell phone chargers, since they are flexible. Solid wires are better electrical conductors and have more rigidity. When there are long wire runs, they are used.

 THWN (thermoplastic high water-resistant nylon-coated) and THHHN (thermoplastic high heat-resistant nylon-coated) are the most popular types of single-conductor wire employed to link the branch circuits and devices. THWN is the name of its counterpart (or THWN-2). This thermoplastic nylon-coated wire is developed to function in the same settings as THHN without needing additional installation gear. However, both THHN and THWN are still commonly used, THWN is regarded as a development of THHN.


The adoption of THWN wire is primarily due to its water resistance. These wires are used when a conduit is not required; this versatility makes it the favored wire among electric contractors, as both types of wire are not required to be carried. To aid in water resistance, hold solely THWN wires coated in PVC rather than vinyl.


THHN is the primary wire version of dual-rated wire. This resistance is developed to tolerate heat up to 194°F. However, it reduces to 167° if oil is exposed. THHN wire is usually a two-conductor used in the ROMEX®-style wiring that runs throughout all residential buildings.

Electrical Interference:

To avoid electrical interference, keep coaxial cables and their splitters about 6 in away from electric wires. Appliance, tv, computer power cables, and any electrical wires in confined spaces, are all examples of electric wires. Telephone wiring can potentially cause electrical interference. When placing telephone wiring in a new place or a renovation, utilize protected telephone wiring whenever practical. If you must connect a coaxial cable near electrical or telephone wiring, make a 90° angle so that the coaxial cable is laid out in a curve-like pattern over the wiring.

Types of Electric Wires:

A conducting metal must form electrical wires; copper is the favored choice because it is one of the best conductors available. Aluminum is a viable option for commercial and high-voltage operations, but it is not of home electrical wiring types, despite being used briefly in the early 1900s.

The thickness of the wire, as determined by its AWG (American wire gauge) number, is the most crucial wire attribute for an electrician. Larger-diameter wires have smaller gauge numbers, and the smaller the gauge number, the more significant current the wire can withstand without overheating. Wire gauges of 8, 10, 12, and 14 AWG are used in household wiring, with 12 AWG being the most prevalent. Wire gauges less than 8 are usually handled only by electricians.


Aside from the safe wiring system, electric wires also have aesthetic importance. These are aesthetically appealing. You will find them durable and reliable in the long run.
