The selected values are used to populate the two lower tables that have standard values. Conduit fill is the amount of a conduit's cross-sectional area that is occupied by a cable or cables, based on the. conduit sizes at the maximum fill ratio specified by the United States National Electrical Code (NEC) for domains.. So, for this example, the calculation for each cable type would be as follows: Coax: 0.79D². Calculating conduit fill is a straightforward process, but important to comply with NEC requirements (National Electrical Code) and avoid expensive rewiring (and most importantly, to keep your electrical installation safe!). The following steps describe these factors and explains how to correctly calculate conduit fill. No. of Cables at 40% Conduit Fill Based on Trade Size of the Conduit (inches). Conduit Fill Guide.

What we are going to do is to see if these two cables can fit in that conduit. There are three different things to take into account when calculating a conduit fill: 1. The number of conductors 2. Total cross-sectional area 3. National Electrical Code (NEC) 2011 standards. The most important variable when selecting your conduit. Southwire has created this great tool to help electricians, engineers and contractors answer the question, “What size conduit do I use" per the NEC®, includes fill percentages and jam probability. If you do not have the NEC book handy or do not want to spend time manually calculating the Conduit Fill %, this is the right app. Divide the 40% conduit area by the conductor area, to determine the number of conductors allowed. NOTE: When calculating conduit fill, if the calculation results in a decimal of 0.8 or larger, you can round to the next whole number.

Conduits or ducts should be properly constructed having smooth walls and of adequate size as determined by the overall cable diameter and recommended percentage of fill of conduit area... diameters are based on percent fill only. The Jam Ratio, Conduit OD to Cable ID, should be checked to avoid possible jamming. calculated in practice. For instance, consider a 10 millimeter (mm) microduct ID and 7.5 mm cable. A formula that uses diameter divided by pathway. ID results in a 75 percent fill ratio. However, the result is different using cross-sectional dimensions, such as. 3.14 x 5 mm radius (squared) = 78 mm2 for area of the conduit and. The NEC's criteria is often used to size conduit. The design parameter for determining minimum conduit size is conduit fill. It's denoted as a percentage. The conduit fill percentage is the ratio of the area of the cables inside to the inner area of the conduit. The calculation for a single cable inside of a conduit.
