Raceway and Box Calculations INTRODUCTION TO UNIT 5—RACEWAY AND BOX CALCULATIONS Anyone who’s ever pulled wire into a conduit understands the reason for maximum limits on the wire fill for raceways. Trying to pull too many conductors into a raceway can damage the conductor insulation due to the friction and mechanical abuse.

Calculating the minimum dimensions of a box containing straight pull (s) is quite simple: multiply the trade size (metric designator) of the largest raceway by eight. For example, calculate the minimum dimension for a pull box with two 2-inch conduits. The conduits are directly across from each other in the ends of a 4-inch wireway.
