I wish the code book would revert back to the good ole days when I could size a conductor for a job by looking in one table for 3 current carrying wires in raceway, and not have to perform 3 seperate alternate calculations to get the best answer. Also I knew how many wires of type thhn for a given size fit into a 3/4" conduit by looking in one single spot in chapter 9. However if the old ways resulted in more fires across the country, then I guess its Aidios old friend, and on with the new.
