Webb8 dec. 2024 · Based on the 2024 N.E.C. National Electrical Code. Ampacity is the maximum continuous current carrying capacity of a wire inside a cable or raceway. It is measured in amperes (amps). The proper amperage is determined by the size of the wire, ambient temperature, number of wires installed together, the types and number of electrical … WebbAmpacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in …
