Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Cerrowire's ampacity chart helps calculate the load requirement for a circuit.
28 maj 2023 · 4/3 is a cable designation - three 4 AWG wires and one ground wire in a common jacket. The ampacity of the cable depends on the temperature rating and conductor material.
At a median 75°C temperature, the ampacity of the 4 AWG copper wire is 85A. Accounting for NEC 80% rule, this means that a 4 AWG copper wire can handle up to 68 amps of current. Depending on the voltage, the 4 AWG copper wire can carry anywhere from 816 watts (12V circuit) to 16320 watts (240V circuit).

AWG – American Wire Gauge Chart – Wire Size & Amps Rating Table. American Wire Gauge “AWG” is one of the important and standard tools in the US NEC (National Electrical Codes) used to sizing different cables and wires for multiple applications.
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 “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
