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®.

Size Raceways for a Successful Installation - EC&M
https://www.ecmweb.com/content/article/20891686/size-raceways-for-a-successful-installation
This installation guideline recommends that raceway runs be limited to 100 feet, have no more than two 90° bends, and have a maximum pull force of 25 pounds for Cat. 5 cable, and have a maximum pull force of 100 pounds for optical fiber cable.
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.

I think you mean article 310.3 for wires in a raceway. O OTT2 Senior Member Location Orygun Jul 22, 2011 #4 If you are referring to conductors installed in raceways take a look at 310.106 (C) in the 2011 NEC. N Npstewart Senior Member Jul 22, 2011 #5 Thanks guys, I actually went to table 8 as charlie suggested immediately after I posted.
Maximum Number of Electrical Wires Allowed in Conduit
https://www.thespruce.com/number-of-electrical-wires-for-conduit-1152860
The allowable number of wires that can be placed inside a conduit varies according to the type and size of the conduit and also on the size of the conducting wires. Wire size is defined by the American Wire Gauge, or AWG, number. The smaller the AWG number, the larger the wire diameter.
