Choosing the right wire gauge (16 AWG vs 18 AWG) for your power cord can prevent overheating and ensure safe operation of your devices. Learn the difference and pick the perfect cord!
18 AWG: This is a thin wire commonly used for low-voltage applications such as doorbells, security systems, and thermostats. 14 AWG: This is the standard size for many residential applications, including 15-amp lighting circuits, bedroom and office outlets, and general-purpose household wiring.

An 18 AWG wire is more flexible than a 16 AWG wire. It is easier to bend and mold into shapes, straps, and around corners than other wire sizes because of how thin it is. If you don’t have a ton of space, you can push 18 AWG wires more tightly together compared with 16 AWG wires.
This blog provides an essential guide to understanding wire sizes, specifically focusing on the American Wire Gauge (AWG) system. It explains how AWG works, its history, and its importance in both Ethernet and electrical installations.
Wire gauge refers to the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors. The smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.
16-gauge: Light-duty 120-volt extension cords drawing a maximum of 13 amps. 18-gauge: Low-voltage lighting and lamp cords that draw a maximum of 10 amps. There are some cases where you’ll use higher-gauge wire for other applications.
A wire gauge chart lists the American Wire Gauge (AWG) sizes for electrical cables and converts them to inches and millimeters. Wire properties such as cross-sectional area, ampacity and resistance are also listed. This guide reviews the differences between the most common types of AWG wires and which gauge sizes are appropriate for common ...
Wire gauge refers to the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.
The diameter of the 16 gauge wire is 1.291 mm. Namely, 16 gauge wire is thicker than 18 gauge wire and thinner than 14 gauge wire. The cross-section of 16 gauge wire in sqmm is 1.31 mm2. Both of these metrics allows us to determine the ampacity and answer the key question:
