Conduit Fill “Maximum Conduit Fill” is the maximum number of cables or conductors that can be installed in a single conduit. 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.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.On my census form it says, 'Your response is required by law.'

Since we had already calculated the total wire area, we can easily calculate the minimum conduit area: 219.98 sq. mm / 0.4 = 549.95 sq. mm. Using a simple lookup, we can find the closest conduit size. Example: If we need to use an EMT conduit, we can find that the closest conduit size is a 1 inch conduit, which gives us a 39% conduit fill.
