NOTES:

1.Ratings for AWG-sized wires are derived from MIL-W- 5088B. Ratings for metric-sized wires are derived from IEC Publication 335-1.

2.Ampacity of aluminum wire is approximately 84% of that listed for copper wire.

3.When two or more wires are bundled together, ampacity for each wire must be reduced to the following percentages:

2 conductors 94%

3 conductors 89%

4 conductors 83%

5 conductors 76%

4.Maximum temperatures: Ambient, 50°C; conductor, 105°C
