Hello: A customer of mine has asked me where he can get a hold of a chart or data for the temperature rise vs. current for heavy copper (4 oz./sq. ft to 8 oz./sq. ft.). The only chart I have ever seen shows values for one or two ounce copper. Are the values linear for heavier copper? Any help would be deeply appreciated. Thanks in advance, and have a great holiday!
