Calculate Your Conduit Fill Percentage. A great tool to help electricians, engineers and contractors answer the question, "What size conduit do I use per the NEC®?" The app will calculate the conduit fill percentages and jam probability for multiple conductors per NEC® Guidelines.
This online conduit fill calculator is compatible with the US National Electrical Code (NEC)! Step One: Select a conduit type and size. Step Two: Enter the insulation type, wire gauge, and amount of wires. Insulation. Gauge. Amount: Add another row. Calculate. Results. Total wire area (mm 2): Conduit area (mm 2): Conduit fill (%):
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.
Conduit Fill Calculator. This conduit size calculator will help you answer two questions: • What size conduit do I need? • How many cables will fit in my conduit? 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.
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.

Step-by-Step Conduit Fill Calculation. Step 1: Identify the conduit type and size from the NEC tables. Step 2: Determine the fill percentage based on the number of wires. Step 3: Calculate the total area occupied by the conductors, using NEC values for each wire size.
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 Conduit Fill Calculator is a powerful tool used in the electrical industry to determine the percentage of conduit space occupied by electrical conductors. It helps ensure that the conduits are not overfilled, which can lead to overheating and other safety hazards, or underfilled, which can result in inefficient use of space.
Locate the conduit type and size on the table. Find the corresponding wire size column and determine the maximum fill capacity expressed as a percentage. The NEC Conduit Fill Table provides a comprehensive reference for wire fill calculations, ensuring safe and compliant electrical installations.
