Ampacity table for aluminum wire
What determines the ampacity of a wire?
The ampacity of the wire is determined by the amount of current in the wire at the point in which the conductor’s temperature rises 30°C. The ampacity rating of higher temperature rated wires is greater than lower temperature rated wires for any given size of conductor. The conductor size selected needs to match the electrical load.
What is the ampacity for 8 AWG wire?
The ampacity of 8 AWG is 40A if you are intending to use NMC cable for this application. Now even if the terminals are rated for 75 degrees you would be sizing based on 60 degrees because of if being NMC. Now be it other than NMC and you have some options.....be it NMC you are limited to the 60 degrees maximum. 334.80 Ampacity.
What size wire do I need calculator?
For example, if you want to create a 12-gauge wire from 20 gauge wires, first select 20 gauge from the Wire Gauge list, then select 12 gauge from the Effective Gauge list; the required number of wires is 6. This calculator determines the effective AWG gage of a combination of wires of differing AWG gages.
What is the ampacity of a copper wire?
Allowable ampacities of insulated copper conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), Not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient temperature of 30°C (86°F).

For example, replace a No. 6 AWG, copper, type TW conductor with an aluminum conductor. Table 310-16 lists the ampacity of No. 6 copper TW (60°C colu mn) at 55 amperes. Now select an aluminum conductor from the 60°C column that has an ampacity of 55 amperes or higher. A No. 4 aluminum would be used to replace the No. 6 copper TW conductor.
