# 40 gauge wire

• ### What is the resistance of a 40 gauge wire?

• Given two wires of the same length, the thicker wire would have smaller resistance than the thinner wire. (e.g., At 25 C, AWG 4 wire has a resistance of.2485惟 for 1000 feet, while AWG 40 wire has a resistance of 1079惟 for 1000 feet.)

• ### What is the diameter of AWG 40 wire?

• For example, AWG 4 is 0.2043 inches in diameter, and AWG 40 is.0031 inches in diameter. The diameter doubles every time the gauge decreases by six levels (e.g., a three-gauge wire has double the diameter of a nine-gauge wire).

• ### What are the different gauge wires?

• We鈥檙e going to simplify every wire鈥檚 characteristics (mm, mm2, amps) 鈥?from AWG 4/0 to AWG 40 gauge wire 鈥?in a systematic and concise easy-to-understand way. Example: Diameters (in mm) for AWG wires from 10 gauge wire to 28 gauge wire. This overview article about AWG gauge wires will give you all the info you need about wire sizing.

• ### What size wire do I need for 40 amps?

• 8 AWG wire has a rated ampacity of 50 amps. That is a perfect wire size for a 40 amp circuit. If you want to have an even safer circuit, you can use 6 AWG wire as the 40 amps wire size. Note: Do inform yourself about the specific characteristics of these wires before you buy one.
