What determines the carrying capacity of a copper wire?
Current Carrying Capacity of Copper Conductors. Heat, caused by an electrical current flowing through a conductor, will determine the amount of current a wire will handle. Theoretically, the amount of current that can be passed through a single bare copper wire can be increased until the heat generated reaches the melting temperature of the copper.
How many amps does an 80 gauge copper wire carry?
In millimeters, 8 gauge copper wire has a diameter of 3.264 mm. That brings the cross-section to 8.37 mm2. With this information, we can determine how many amps will an 80 gauge carry. For everybody wondering if the 8 AWG wire can handle 50 amps, here is the answer: The ampacity of the 8 gauge wire is exactly 50 amps at 75C.
How many amps can a 1 AWG wire handle?
Given the 42.4 mm2 thickness, the 1 AWG copper wire has a current-carrying ampacity of 130 amps at 75C. This gives us a pretty good indication of how many amps can a 1 AWG gauge wire handle. With 130 amps capacity, 1 gauge wire can serve as a battery cable, welding cable, or any other power cable that requires a good 100 amps of electric current.
What size wire for 20 amps?
14 AWG wire has a rated ampacity of 20 amps. That is a perfect wire size for a 20 amp circuit. If you want to have an even safer circuit, you can use 12 AWG wire as the 20 amps wire size. Note: Do inform yourself about the specific characteristics of these wires before you buy one.
