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®.

The desired fill ratio is 40%. The wire mesh cable tray is 2 in. (51mm) high by 2 in. (51mm) wide. A = 3.5 in.2 D = .19 in. F = 40% N = ( 40/100 ) * ( 3.5 / [ (.19/2)2 * Π]) = 49 cables Cable Load / foot = 49 cables * 20 lb/1000 ft. = 0.98 lb/ft Below is the data for Quick Tray Wire Mesh Cable Tray Fill Table at 50% Fills.

The column you want to use is "Over 2 Wires," since we have some 60 wires and want a 40% fill. Accommodating all of our wire will require a 1 1/2 in. EMT. Now that we've covered how to determine raceway fill, let's cover some basic concerns on conduit selection. Remember that the Code is not a design manual.

Calculating raceway fill. You can't use Annex C tables to determine raceway fill for conductors of different sizes in the same raceway. To do so, use the following steps: Step 1. Determine the cross-sectional area of each conductor. Use Chapter 9, Table 5 for insulated conductors and Chapter 9, Table 8 for bare conductors. Step 2

National Electrical Code explanation: Conduit Fill
http://www.codebookcity.com/codearticles/nec/conduitfill.htm
One wire can fill only 53% of a raceway, and two wires can fill only 31%. And if you have more than 2 conductors in a raceway, the maximum fill is 40%. That 40% is subject to further downward adjustment, though. The Authority Having Jurisdiction (AHJ) can require even less fill--so, use common sense. Read the FPN in Table 1 thoroughly.
