Product Information

You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 25 amps is 12 AWG wire. If a load is expected to ever remain on for longer than 3 hours, the conductor needs to be rated for 1. It is because the electrical signals in these wires have low power, and thus you do not need smaller AWG wires. There are 39-gauge sizes between these two sizes which you can get through logarithmic calculations.

We rarely do use it but when we do it’s useful to know the dimensions of 5 gauge wire in mm (diameter) and mm2 (cross-section). Here is a range of applications such a wire can be used for (Fermerry 28 AWG wire): Applications of a 28 gauge copper wire. You will find subchapters covering 10 amp, 15 amp, 20 amp, 25 amp, 30 amp, 40 amp, 50 amp, 60 amp, 70 amp, 80 amp, 90 amp, 100 amp, and 200 amp wire sizes in the 2nd Chapter. That means it can handle 15 amps well, for example, since it is limited by the maximum current of 17 amps.Example of a good simplification: The higher the AWG gauge wire numbers (like 14, 16, 20, 40), the thinner the wire.

If you use the mm diameter of the 1/0 gauge wire, you can calculate the full cross-section in mm2 to be 53. For AWG 23 and upwards - When using a cable to power mains voltages: (110v, 230v etc) the smallest conductor we recommend is 0. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants. If you’re looking for wire size for a 100 amp circuit (this can be for a 100 amp 220-volt circuit, breaker, battery output), you will need an AWG with at least 100 amp rated ampacity at 75°C. Here is one such very affordable example of a 4 gauge wire by InstallGear: InstallGear’s 4 gauge wire.Formula for calculating the cross-section (Area; An) of an AWG wire (n denotes the AWG gauge number). The key part is that we cover each wire individually; from the big 4/0 – 1/0 wires to the most popular 12 gauge, 14 gauge, 16 gauge wires, and down to the smallest 40 AWG gauge wire. You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 30 amps is 10 AWG wire. If you need a wire to handle a certain amount of amps you can just scroll down to the appropriate subchapter that covers the amperage you’re interested in. If you’re looking for wire size for a 20 amp circuit (this can be for a 20 amp 220-volt circuit, breaker, battery output), you will need an AWG with at least 20 amp rated ampacity at 75°C.
