Limits on conduit fill are set by the National Electrical Code (NEC). These limits were created to prevent mechanical damage to cables during installation as well as overheating of cables in service. For certain conditions, a larger size conduit or lower conduit fill should be considered. For 3 or more conductors, if the ratio of the raceway inside diameter to the conductor or cable outside diameter is between 2.8 and 3.2, considerable probability of jamming can occur (much lower probability for other ratios).
