What Is The Electric Wire Gauge?

The electric wire gauge is the wire size measurement used to determine the size of an electric cable. It is a standard metric unit that equates to the cross-sectional area of a solid circular conductor. A thinner, more flexible cable may be smaller in diameter and still be at least as thick as one with a larger diameter.

There are a few things you should know about electric wire gauge, before starting any wiring project. First, it's important to understand the terms AWG and American Wire Gauge (AWG). Second, be sure to use the right electric wire gauge for the job. Finally, always use a voltmeter to test the circuit before beginning. With these tips in mind, you'll be able to get started with your wiring project safely and correctly.

Types of Electric Wire Gauges

There are a few types of electric wire gauges. The most common type is the AWG or American Wire Gauge. This gauge measures the diameter of an electric wire. It is usually expressed in terms of the number of wires per inch (AWG), thousands of wires per mile, and millimeters per kilometer. Other types of gauges include the British Wire Gauge (BGA), which measures the thickness of an electric wire, and the European Wire Gauge (EWG), which measures both the thickness and diameter of an electric wire.

How to Calculate Your Lowest Wire Gauge

In order to determine your lowest wire gauge, you will need to take into account the thickness of the wire, the diameter of the wire, and the number of strands in the wire. 

To calculate the thickness of the wire, divide the diameter of the wire by its circumference. 

Example: A wire has a diameter of 0.049 inches and a circumference of 2.54 inches. So, dividing 0.049 by 2.54 results in a thickness of 0.021 inches.
