What is the ampacity of wire wire wire?
Wire Ampacity Tables. For Ambient Temperatures Over 30 C, 86 F, multiply the ampacities shown above by the appropriate factor show below: 1 The load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum …
What is the ampacity of a conductor?
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 is the maximum ampere rating for a 12 gauge wire?
1 The load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.
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.
