If the wire has a lower current carrying capacity than the power running through it, it could overheat. The size of the wire affects the amperage rating, which is why it’s important to know the right size for your needs (to use the wire size chart). AWG wires are listed in reverse, meaning the smaller numbers are the thickest wires while the largest numbers are the thinnest. If you don’t use the correct wire size for your project, you could end up with an electrical incident. You can refer to the table on wire sizes and their applications in the previous section for clarification. This aids in determining the right application for each wire. The sizes help electrical professionals determine the right application for different wire sizes.ĪWG is also responsible for providing the ampacity of different wire sizes. The American Wire Gauge (AWG) is the dominant sizing system for wires in the US. Unfortunately, aluminum wires are less durable than copper wires. On the other hand, aluminum is much lighter and also a good conductor of electricity. Copper is an excellent conductor used in various scenarios, but it’s expensive and pretty heavy. There are two types of wire used for electrical applications copper and aluminum. The first thing to determine is the type of wire you need. There are various considerations that can guide you in choosing the right wire size. Related: Screw Size Chart And Thread Count Guide

The 310-16 code suggests adding an extra 20 of the wire’s ampacity for 30 amps every time the distance increases to 100 feet. So, with 37.5A ampacity, an 8 AWG wire after 10 AWG wire will perfectly fit 30 amps.
