Understanding Electric Cables
An electric cable is an assembly of one or more wires running side by side or bundled together, used to carry electric current1. The terms wire and cable are often used interchangeably, but technically, a wire is one electrical conductor, and a cable is a group of wires, or conductors, encased in sheathing2.
Electric wires are typically made of aluminum or copper and can be either bare or insulated. If they have a thermoplastic sheath, the thermoplastic is colored to indicate whether the wire is a neutral, ground, or hot wire in your electrical installation2.
Types of Electric Cables
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 thermoplastic2.
The most common types of electrical wires used in residential applications are usually nylon coated thermoplastic with a high-heat resistance2. Wires are labeled with the material, maximum voltage rating, and gauge2.
Wire Material
Most wire will be marked “CU” for copper, the most common conductor of residential electricity. Because electricity travels on the outside of copper wire, these wires are insulated to protect against fire and shock2. Aluminum wire is more conductive than copper wire, but it also degrades faster2.
Applications of Electric Cables
Electric cables are used in a variety of applications, from doorbell wiring and thermostat wiring to speaker wire, ethernet cord wires, weatherproof wiring connectors, and more3. The type of cable used depends on the specific requirements of the application.
In conclusion, electric cables play a crucial role in our daily lives. They power our homes, enable our communications, and even charge our electric cars. As technology continues to advance, the importance of understanding and properly using electric cables will only grow.
