How many amps for 12 awg
WebSep 18, 2024 · “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].” These rules of thumb are referring to the amperage capacity or “ampacity” of the conductor (wire) and are often correct. WebEach has a different ampacity for a specified gauge size, and these ampacities are found in NEC® Table 310.15 (B) (16) for the calculations in this app. For example, 3/0 AWG copper has an ampacity of 200 amps at 75℃, while 3/0 AWG aluminum has an ampacity of 155 amps at 75℃.
