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. A great tool to help electricians, engineers and contractors answer the question, "What size conduit do I use per the NEC®?"

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.

Use the below charts to determine the number of wires that can be put into conduit tubing, while maintaining NEC standards. 2-hour fire-rated RHH cable has ceramifiable insulation which has much larger diameters than other RHH wires. Consult manufacturer’s conduit fill tables. *Types RHH, RHW, and RHW-2 without outer covering.

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."

Each row going across is a different size of PVC conduit (Schedule 40 or 80). Each column (going up and down) is a different gauge of wire. The results show the allowable number of wires for each size/type of conduit and wire, based on the 2020 NEC code.

The following is a typical conduit fill chart, which shows data for different types of conduit such as EMT conduit, IMC conduit, and GRC conduit. The possible wire gauges go from 14 AWG to 750 MCM, and from conduit trade sizes of 1/2 inches to 4 inches.

A Conduit Fill Calculator is a tool designed to determine how much space wires or cables occupy within an electrical conduit. It helps ensure compliance with NEC guidelines, which regulate the maximum fill percentage for different conduit types and sizes.

2024年12月25日 · Allowable fill area (A_allowable) = Fill percentage × Area of conduit (A_conduit) Step 5: Compare Total Conductor Area to Allowable Area. To ensure compliance: Check if A_total ≤ A_allowable. If the total conductor area exceeds the allowable area, a larger conduit is needed. Reference Table for Common Conduit Sizes and Fill Percentages

This conduit fill table is used to determine how many wires can be safely put into non-PVC conduit tubing or pipe. Each row going across is a diferent size and type of conduit, either EMT, IMC, or galvanized pipe (rigid metal conduit, RMC). Each column (going up and down) is a …
