Ampacity Charts. 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.
16 gru 2023 · Here is the table that comes with different values, like the resistance of wire gauges and the current value for copper conductors with plastic insulation. The diameter details in the table are for solid wires. Standard wires are measured by measuring the equivalent cross-sectional copper area. AWG#.
The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), 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).
Cable Size & Current Rating Chart. * This chart is to be used as a guide only. Please consult your cable suppliers specifications for true values. The team have been exceptionally helpful, friendly and patient, especially as they're dealing with a particularly non-technical customer like me.
The following tables are to be used in series to determine a wire's ampacity in a given application. Section 6 should be used as a reference for examples of applications of these tables. Base Ampacities.
