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
