Aluminum busbar ampacity tables 1

busbar,
Thanks for the response. I am specifically seeking current ratings (ampacities) of rectangular aluminum bar of a 6101 alloy (electrical grade aluminum). The tables specify size (1/4" x "x", 1/2" x "x", etc.), orientation (horizontal or vertical mount), number of parallel bars, and alloy versus current ratings. Alcoa used to publish a handbook with tables such as I am seeking; however, I do not have a handbook and Alcoa can't seem to locate one.
P.S. I could not locate the code section quote you listed in the 2002 NEC. Did you make a typo or am I looking in the wrong section?

Try this, IT's the onlline version of the "Technical Data- A reference for the Electrical Power Industry". It's worth downloading and sticking on a CD.

I found this guide which shows how to calculate the current rating. I ran a couple size variations and the results were close to the tables I have. All the tables I have found stop at 1/2" thick bar.
