Conduit Fill Chart. This table provides the initial recommended 40% fill capacity for Ethernet and coaxial cable based upon conduit trade size and cable jacket diameter. Take note that conduit less than 3/4” (3/4 trade size) is not recommended for communications cable installation.

To find out how many cables you can run in a given conduit size, enter your Belden cable part number, or enter the diameter of your cable. Next, select the type of conduit you are specifying. Then, under Conduit Size, select the size of your conduit and hit "Calculate."
We will explore the different conduit sizes, cable diameters, bend radius requirements, and types of conduits that can be used. Additionally, we will introduce conduit fill charts, which are useful references for calculating the maximum number of cables allowed in a specific conduit size.
Using a 6.5mm (0.256) Diameter cable, you can fit only 5 cables per conduit. However, this assumes the cables are perfectly circular and non-deformable. If you assume you can deform the cables, or you use a slightly smaller cable, you can fit up to 7 without destroying the cables.
Our NEC Conduit Fill Chart calculates THWN and THHN wire fill for EMT, IMT, rigid metal, or flexible metal conduit pipe using conduit trade size and AWG or MCM wire size.
The app will calculate the conduit fill percentages and jam probability for multiple conductors per NEC® Guidelines. Simply enter the conduit type and size, then specify your conductors.
The ratio can be used to determine appropriate conduit size or determine how many cables can be placed in an existing conduit. The maximum recommended ratio can be affected by several factors, including application type, number of cables in the conduit, and the number of conduit bends.
