18 awg vs 20 awg American wire gauge AWG to mm and mm2 conversion calculator chart and how to convert
You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 10 amps is 20 AWG wire 20 AWG wire has a rated ampacity of 11 amps That is a perfect wire size for a 10 amp circuit If you want to have an even safer circuit you can use 18 AWG wire as the 10 amps wire size The following AWG American Wire Gauge table shows the AWG Size and diameter in millimeter mm and inches in in its cross sectional area in mm 2 Inche 2 and kcmil or MCM and resistance in ohms per 1000 feet and 1000 meter The AWG size chart also shows the current in amperes for chassis wiring and power transfer application

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 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 Learn about wire gauge resistance ampacity and more in this comprehensive article
The higher the wire AWG gauge the less mm diameter a wire has Example 12 AWG wire has a diameter of over 2 mm and 20 AWG has a below 1 mm diameter In theory you convert AWG gauge to mm using this somewhat complex AWG to mm formula In practice we prefer to use a simple AWG to mm chart Even at max current 3A the 20 AWG would probably handle at least twice the amps specified on that product but one does have to wonder why the product engineer spec d a unit with 18 AWG wire originally convenience compatibility safety margin

E g 1 mm diameter wire is 18 AWG 2 mm diameter wire is 12 AWG and 4 mm diameter wire is 6 AWG This quadruples the cross sectional area and conductance A decrease of ten gauge numbers E g from 12 AWG to 2 AWG multiplies the area and weight by approximately 10 and reduces the electrical resistance and increases the conductance by A light duty 18 AWG power cord is good for about 5 amps That s OK for a PC with up to a 600 watt power supply Above 600 watts assuming your computer is actually using that much power you push the limits of an 18 AWG power cord and can expect the cord to heat up and possibly malfunction
Learn wire gauge size and the American Wire Gauge AWG standard to help you determine what gauge to use for your car audio system If you re buying wires by size in inches or millimeters or have stripped and measured uninsulated wires with a gauge tool you can also use a wire gauge chart to determine the maximum amperage of a wire Most charts provide ampacity for copper and aluminum wire and their most common insulation materials The Spruce Mira Norian
