National Electrical Code Allowable Ampacities of Insulated Conductors Rated 0-2000 Volts. As Excerpted from the 2002 National Electrical Code. Ampacities of Not More Than Three Current-Carrying Conductors in Raceway, Cable or Earth. Based on Ampbient Temperature of 30°C (86°F)
Whenever we need to need how many amps a wire can handle, we turn to the NEC 310.16 table. The 310.16 table is basically an ampacity chart; it tells us what is the ampacity of copper and aluminum wires.
Conductor Ampacity Based on the 2017 National Electrical Code ®. Single-Phase Dwelling Services and Feeders. NEC 210.19 Conductors–Minimum Ampacity and Size. Correction and Adjustment Factors—See NEC Tables 310.15 (B) (2) (a) and 310.15 (B) (3) (a) NEC Information of Note.
The wire size chart below shows allowable ampacities of insulated 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 air temperature of 30°C (86°F).
