Cables contain at least a neutral wire, ground wire and hot wire that are twisted or bonded together. Depending on its purpose, the cable may contain more wires. The wires in a cable are insulated in their own color-coded layer of thermoplastic. The group of wires is then encased in an outer sheath to make up the single cable. Wire Labeling

INDEX Electrical cable Voltage An electric cable is measured in volts and, depending on these, they are categorized into one group or another: Low voltage cables (up to 750 V): in a variety of applications, and with thermoplastic and thermoset coatings. They are designed and built according to harmonized standards.

The electrical cables can be used in low-voltage, medium-voltage, high-voltage, and extra-high-voltage applications. But in this blog post, we will consider low-voltage applications. The operating voltage in low-voltage cables can be (up to 1.8/3 KV), as the voltage of a cable will be written in the following formula U0/U (Um).

An electrical cable is classified by two numbers separated by a hyphen, such as 14-2. The first number denotes the conductor's gauge; the second denotes the number of conductors inside the cable. For instance, 14-2 has two 14-gauge conductors: a hot and a neutral. This cable also contains a bare copper wire as the ground.

Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity and auxiliary control cable. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting.
Types and Sizes of Electrical Cables and Wiring
Most interior wiring is done with non-metallic, or NM, cable—also known by the popular brand name Romex. NM cable is made of three or more wires wrapped inside a flexible plastic jacket, or sheathing. It is used for most interior circuits, such as those for outlets, switches, light fixtures, and appliances.
