First, let's expand things a bit. Conduit is a specific kind of raceway. So, we're really talking about raceway fill--whether that raceway is conduit, EMT, NMT or some other kind of raceway. The NEC index cross-references "conduit fill" as conductor fill. The basic NEC reference is 300.17.

The Code generally permits up to a 40 percent fill for conduits containing more than two conductors, as provided in NEC Chapter 9, Table 1. The reason for limiting the fill to 25 percent of the conduit cross-sectional area of the sealed raceway is to provide adequate room in the fitting for separating the conductors and achieving an effective seal.
