What is wire size and AMP capacity?
Wire Size Amp Ratings. Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or 鈥渁mps.鈥? You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
What size wire do I need for 50 amps?
8 AWG wire has a rated ampacity of 55 amps. That is a perfect wire size for a 50 amp circuit. If you want to have an even safer circuit, you can use 6 AWG wire as the 50 amps wire size. Note: Do inform yourself about the specific characteristics of these wires before you buy one.

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.
