We often use wires in our lives. When selecting wire, it is important to choose based on the principle that the size of the wire must match the current of the circuit.

The confusion of wire size selection


When we buy wires, we may have noticed that there are many types and sizes of wires. Different types of wire can be used for different purposes, but for any of these wire types, knowing the correct wire size or gauge is the key to making the right choice.

Wire sizes are determined by the American Wire Gauge (AWG) system. Wire gauge is a guide to the physical size of the wire, and its rating number is the opposite of the wire diameter, which means the smaller the gauge number, the larger the wire diameter. Common sizes include 14 gauge wire, 12 gauge wire, 10 gauge wire, 8 gauge wire, 6 gauge wire, and 2 gauge wire. The size of the wire determines how much current can safely pass through the wire.

Choosing the right wire


One thing to remember when using electrical wire in your home is to choose the style of wire that best suits your needs. Some wires are stranded together, while others are made of solid copper wire. In installations using metal piping, solid wire is not always easy to pull if there are many bends in the pipe. However, solid wire is usually easier to secure under screw terminals, such as those on standard switches and sockets. However, in standard use, the conductor in conduit or NM cable used for home wiring is a 14, 12 or 10 gauge solid copper conductor.
