1. Current ratings are based on 6101-T61 alloy with standard vent-holes in web. For 6101-T6 reduce the rating by 2 percent. Indoor ratings are based on 30C rise over 40C ambient in still but unconfined air, normally oxidized surface (e=0.35) and similarly for outdoor ratings, except 2 ft/sec cross wind (e=0.50). Horizontal mounting is assumed with spacing sufficient to eliminate proximity effects, generally assumed to be 18-in. or over. For temperature rise of 50C above 40C ambient, the indoor ratings for 30C may be increased about 30 percent. Indoor ratings (D-C and A-C) calculated by computer and verified by test rounded. Outdoor ratings are calculations only.

Outdoor ratings are based similarly, but with 2 ft/sec crosswind (e=0.50). Horizontal mounting is assumed with spacing sufficient to eliminate proximity effects, generally assumed to be 18-in. or over Indoor ratings based on work by House and Tuttle.
