  • What is ampacity of wire?

  • Wire Size Amp Ratings 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 are the ampacities of insulated copper conductors?

  • Allowable ampacities of insulated copper conductors rated up to and including 2000 Volts, 60C through 90C (140F through 194F), Not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient temperature of 30C (86F).

  • Where can I find an ampacity chart for copper?

  • This table is generally used for currents above 300 amps. For currents below 300 amps, please refer to the design guide formula. You can find ampacity charts and comparative graphs at the Copper Development Association鈥檚 website, copper.org.
