Raceway Fill Calculator - Cerrowire
https://www.cerrowire.com/products/resources/tables-calculators/raceway-fill-calculator/
Raceway Fill Calculator. The purpose of this calculator is to determine one of two values: the maximum number of conductors (wires) that can fit into a given type and size of raceway, or the minimum trade size of a raceway that is required for a given combination of conductors (wires). All calculations are based on the National Electrical Code®.

Often, a wiring harness will have eight conductors; three phases, three neutrals (one per phase), an equipment ground conductor, and an isolated ground conductor. Flat Conductor Cables (FCC) These offer similar flexibility to that of an access floor system in that such cables permit outlets to be located anywhere in a room and allow easy relocation of an outlet.

The raceway is more than 200 feet long, and it contains three 500 kcmil THHN conductors, one 250 kcmil THHN conductor, and one 3 AWG THHN conductor. What size RNC raceway is required for these conductors? (a) 2 inches (b) 2.5 inches (c) 3 inches (d) 3.5 inches. Step 1: Determine the cross-sectional area of each conductor by referring to Table 5, Chapter 9.
