16 gru 2023 · What is Wire Size and Amp Ratings? The highest current that can be handled by the conductor is known as ampacity. The current measuring unit is the ampere. So use accurate wire for the current requirements of the circuit to prevent the wire from overheating.
Wire Size Chart for Conductors in Free Air. The ampacity chart below shows the allowable ampacities of single-insulated electrical wire rated up to and including 2000 Volts in free air, based on Ambient Air Temperature of 30°C (86°F).
At 75°C, the 1/0 copper wire ampacity is 150 amps; essentially, the 1/0 W wire is a 150 amp wire size. At 60°C, it can handle up to 125 amps, and it can handle up to 170 amps at higher temperatures (90°C).
The Wire Ampacity Calculator will quickly calculate the maximum allowable current through a conductor based on wire size (AWG or kcmil), wire insulation, conductor type and installation method. Enter the information below to calculate the maximum allowable ampacity for current-carrying conductors.
This app uses the calculation requirements found in the 2017 National Electrical Code® to determine the ampacity of insulated conductors and certain cable-type wiring methods. This calculator also complies with the 2020 NEC requirements.
