In the wire & cable industry, we can see several stories related to wires and cables. From the top 8 wire and cable stores of the year, we have compiled this useful list of questions and answers.

How do electrical cables work?

Electrical cables are designed to offer a low resistance path for the current to flow. These cables are featured to ensure good conductivity. They can be made with either aluminum or copper with other material layers such as insulation, tapes, sheathing and armoring for mechanical protection. These cables are used or connecting two or more devices to transfer electrical signals or we can say carry electric current.

What is voltage rating?

Voltage rating is the highest voltage that is applied to a cable construction, adhering to the industry standard. It is the voltage that a cable remains stable in operation. When you buy cables, you can see voltage to be written as 0.6/1 (1.2)kV. The figure in the bracket is the maximum voltage at which the cable will remain stable and operate safely.

What are AC and DC?

Both AC and DC represent the kinds of current flow in a circuit. When it comes to direct current (DC), the electric current flows only in one direction. In alternating current (AC), the electric current changes its direction. In-house, when you put wired plugs into the outlet, you do not get DC. These outlets in your house are AC.

What is the biggest size cable a cable manufacturer makes?

Leading cable and wire manufacturers can build wires of different sizes. The cables can be as small as 30 AWG. Depending on where the cables need to be used, the size can vary. The large sizes can be 500 MCM, 750 MCM, 1000 MCM, 1500 MCM, 2000 MCM, 2500 MCM, and 3000 MCM and so on.

What is an ampere?

You may be familiar with the word ‘Ampere.’ Commonly referred to as ‘AMP’, an ampere is the standard unit of current. ‘A’ is the symbol of ampere on the cable wires. See it when purchasing a new cable.

If you buy cables for low-voltage lighting and lamp cords, choose 10 amps wires. However, go for 13 amps cables for extension cords (light-duty). 15 amps are ideal for light fixtures, such as lamps or lighting circuits. When it comes to the bathroom, kitchen, outdoor outlets or 120-volt air conditioners, choose 20 amps wires.

These questions and answers from the top 8 wire and cable stories of the year will help you when buying the right wires and cables for households.
