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.

In the May issue, we described the Division system outlined in the NEC, which further breaks down the class. If the ignitable material is normally present (in sufficient quantities to present a hazard), then it’s a Div. 1 location.

Even if NEC conduit fill chart allows say 6 conductors to be carried in a pipe, other calculations/factors and practical experience may limit the number of conductors to 3. I should really prepare a calculations spreadsheet for myself that takes into account all NEC derating tables and other requirements. Calculations dealing with conduit fill and conductor ampacity for Class 2, Class 3, or power-limited fire alarm circuits, as you can see, are easy if you follow the few simple rules in the NEC.

Mar 7, 2009. #4. nhfire77 said: I cannot point to a specific reference here, but yes conduit fill applies to Fire alarm circuits, limited and nonlimited, at least in my experience. I was called on it once by an inspector in fact, but it was less than 24" so the nipple rule covered it. I think your inspector was wrong.The following table provides maximum recommended fill for many standard conduit sizes at the maximum fill ratio specified by the United States National Electrical Code (NEC) for domains within its scope. This also assumes no more than two 90° bends between pull points. Guidance is also provided below on how to calculate conduit fill.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.NEC Table Used To Select Conductor Area. NEC Chapter 9 Table 5 is used to calculate the total area of conductors. NEC Table Used To Calculate Conduit Size. NEC Chapter 9 Table 4 is used to calculate conduit size, through dimensions and percent area of chosen conduit, using the total calculated conductor area. 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). Senior Member. Stuffed to the gills no but if a nipple is 24" or less then the fill ratio goes up to 60% from the typical 40%. Also there is no derating required {310.15 (B) (3) (a)}. Also look at Chapter 9, Notes to Tables #4. 60% is pretty close to being stuffed to the gills though.Conduit fill is essential to prevent overheating and ensure safe electrical operation by avoiding overcrowding of wires within a conduit.
