This chart is based on the maximum number of cables permitted in conduit under the National Electric Code (NEC) and is calculated on the area of the cables with 40% of the conduit filled. For conduit runs of 50 to 100ft, the installed number should be reduced by 15% or use the next size larger conduit. Each 90° conduit bend may be estimated as equal to the friction of 30ft of the straight level conduit.
