Wire Gauge Conversion Example

For ambient temperatures of 86°F (30°C), the maximum current in aluminum wire can be estimated using standard AWG ratings. A 6 mm² wire cross-section falls between AWG #9 and #10; conservatively using AWG #10, the maximum current is approximately 30 amps. This aligns with typical current capacity diagrams for aluminum conductors.
