Nec conduit fill.

The NEC fill calculations affect conduits. Due to conduit pulling requirements NEC reduces the percentage of the cross sectional area of a conduit that can be filled according to the cable count in the conduit. The conduit fill calculation in EDS is calculated as follows: Conduit Cross Sectional area = CCF; (Single CF value in EDS tray catalog)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.I have two segments of conduit: Conduit 1 (Distributor), direct from electrical panel to a distribution junction box 1; Conduit 2 (Branch), from distribution junction box 1 towards branch junction box 2 with a single outlet; Per NEC table 310.15(B)(3)(a), I must derate ampacity relative to tables 310.15(B)(16) through 310.15(B)(19):Conduit fill = (Area of wires in conduit) / (Cross-sectional area of conduit) The NEC tables for conduit fill are based on the following assumptions: The wires are stranded.
