Just seeing what the opinion of others is with information on voltage drop in the CEC. Tables D3&D4 are great but there is no table for three phase. I wonder why they didn't put a table or some information to use so you can calculate the voltage drop.
The formula VD= (1.73)(K)(L)(I) divided by CM is nowhere to be found in the CEC. I have not found the K values at different temperatures in the CEC. Also in the CEC there is no longer the CM of the wire, Table D5 only gives the conductor area in mm2. I know that there used to be more information on this matter in older code books but was taken out of newer ones. Why don't they put a table in the CEC that displays the metric formula for calculating voltage drop in three phase circuits along with the K values of conductors at different temperatures? Maybe I'm just missing a page or something. What do you guys think? Hopefully this starts people talking on this great site.
