Having NEC 2005, I look after NEC 2002 table B.310.6 to compare if there were modifications between the two editions.
An engineering company provide me cable calculation note which states NEC 2002, ampacities table B.310.6 were available with 3,6 and 9 electrical ducts as the max case, but I could only find 6 electrical ducts in 2005 issue.
