WebDetermine the maximum amount of electrical current (amps) that can safely flow through different wire gauges. This table provides you with the allowable ampacity (maximum current the cable can carry) that you can use with wires in conduit, raceway, cable or directly buried, assuming an ambient temperature of 86°F (30°C). Copper Conductor Temp. WebAs we will see in the NEC ampacity chart, copper wires can handle more amps than same-size aluminum wires. That’s because copper has a lower resistivity (1.72 × 10 -8 Ohm×m at 68°F) than aluminum (2.65 × 10 -8 …
WebJan 26, 2024 · The devices they used were not compatible with aluminum wire. As a result, the aluminum conductors loosened up under the screws and started fires. All wires, when carrying current, heat up. And when they heat up, they expand. And when they cool, they contract. Aluminum expands and contracts 35% greater than copper. Webwhich should result in copper being able to carry more current than gold for a given bond wire length and diameter. The equation does not extrapolate the current carrying …
