Notes:
- All data calculations are based on current CEC 2023.
- Wire sizes #14 to #10 are calculated as solid conductors, while all remaining larger sizes are calculated as stranded.
- This system is NOT designed for mixing different insulation types in the same conduit. RW90 is suggested if you intend to use this Conduit Fill Calculator for a mixed run of RW90 and T90.
Instructions:
- Select the intended Conduit Fill %, Conduit Type and Wire type from the second row.
- Enter the Quantity of each wire size on the right. Each row is for one conduit run.
- C. Type/Size column shows the required conduit size as the input quantity of wires changes in each row.
- The first 4 columns on the left are shown for reference only, the columns on the right are for conduit fill calculation.
