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. Table 310.104 (A) shows MTW as a conductor acceptable at 60C for wet location and 90C for dry location so it must be code compliant. Agreed, but Table 310.104 shows the approved use of MTW as machine tool wiring. Totally irrelevant if the wire in question has six other listings, such as the Southwire Simpull you referenced.Ampacity based on NEC ® Table 310.15 (B) (16) (formerly Table 310.16) Allowable Ampacities of Insulated Conductors Rated Up to and Including 2000 Volts, 60° through 90°C (140° through 194°F), Not More Than Three Current-Carrying Conductors in Raceway, Cable, or Earth (Directly Buried), Based on Ambient Temperature of 30°C (86°F).

Above information referenced from Table C.1(A), Table C.4(A), and Table C.9(A) in the 2020 NEC® (National Electric Code®). For more information on filling the following types of conduit with compacted conductors, please see the tables listed below in the Appendix C of the National Electric Code® (NEC®) of 2020.

Conduit Fill Calculator. Conduit Fill is the percent of area inside the conduit taken up by the cable\(s\). Provides quick and easy results for the conduit fill percent, per NEC® guidelines. Go to Calculator.Even if conduit is used for permanent cable installation in a space where the need to later inspect or add more cables would be unlikely (e.g., in concrete), conduit fill is still limited by code. In fact, the maximum fill ratio for conduit per the NEC is 53% for one cable, 31% for two cables, and 40% for three or more cables. The diagram shows conductors/cables lying in a conduit in sets of one, two, three and four. NEC 2011 Chapter 9, table 1, shows that the maximum conduit allowance. As you can see two conductors is the smallest maximum fill. Looking back to the diagram, this is due to the two conductors or cables forming an oval, rather than a circle. 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.The following is intended to provide some clarity to the requirements in NEC 314.28. 314.28 (A) Minimum Size. The smallest size conduit or tubing hub provided in a conduit body is metric designator 16 (trade size 1/2). Since only one 4 AWG conductor consumes the maximum wire fill for 16 (1/2) conduit or tubing, conduit bodies having …

Table 2 in Chapter 9, which covers both manual and machine bending of the raceway, provides field bend requirements for conduit and tubing.The NEC specifications are: One wire: maximum fill is 53% of the space inside a conduit. Two wires: maximum fill is 31%. Three wires or more: maximum fill is 40% of the conduit’s total available space. Using the wire cross-sectional areas you’ve already calculated, you can now determine the minimum conduit size that you need.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.Tip #4: Use conduit supports.
