Dear johnson,

I typically use the 40% rule for raceways with 3 or more cables

Calculate the area of the raceway: l x w = A
Multiply the result by 40%, the result is the usable space for round cables.

Calculate the area of your cable: Pi(r)Sq = A

Divide the usable space of the raceway by the result of the second formula for the number of cable that will fit (drop any fractional remainder)

Sincerely,
Joseph Golan, RCDD
