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.
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.
Simplify complex wire ampacity calculations with Cerrowire’s convenient Online Ampacity Calculator. This intuitive calculator takes the guesswork out of electrical code compliance, ensuring you select the right conductor size for your specific application.
