12awg max amps

Best answer


The allowable ampacity of 12AWG copper wire (with typical insulation types) ranges from 30-40 amps. However,the code specifically remarks,that the mininum overcurrent protection (read fuse or breaker) SHALL NOT EXCEED:

  • How many amps does a 12-gauge wire carry?

  • When wiring chassis, 12-gauge wire can carry a maximum of 41 amps along the metal conductor. The conductive part of a 12-gauge wire is 0.0808 inch in diameter. This gauge is found in extension cords.

  • 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.

  • What is the ampacity of a 20 gauge wire?

  • If you translate 20 AWG to mm, you are dealing with 9.266 mm thick AWG wire. The ampacity of the 00 gauge wire is determined primarily by the cross-section. The complete cross-section of 2/0 gauge wire in mm2 is 67.4 mm2. 2/0 gauge wire is thus smaller than 3/0 gauge wire but bigger than 1/0 gauge wire we cover further on.
