The number of wires you can fit inside a conduit is usually 12 if they re all 12 AWG wires or 7 if 10 AWG The 40 fill ratio for 3 or more wires limits the number to allow proper installation and future additions SIZE 14 12 10 8 6 4 3 2 1 1 0 2 0 3 0 4 0 250 300 350 400 500 600 750 1 2 EMT 12 9 5 3 2 1 1 1 1 1 Conduit Fill Tables NEC Table C Conductor Size Awg Kcmil THHN THWN SIZE 14 12 10 8 6 4 3 2 1 1 0 2 0 3 0 4 0 250 300 350 400 500 600 750 2 EMT 241 176 111 64 46 28 24 20 15 12 10 8 7 6 5 4 4 3 2 1

The fill chart above allows you to determine how many wires can go inside a given conduit and not exceed a 40 fill rate If you have a fixed conduit type and size Find the conduit type and size on the first column for example lets say we have a 1 inch EMT conduit Tools 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
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 Conduit Wire Fill Trade Size Type Wire Size THWN THHN Conductor Size AWG kcmil 14 12 10 8 6 4 3 2 1 1 0 2 0 3 0 4 0 250 300 350 400 500 600 700 750 1 2 EMT 12 9 5 3 2 1 1 1 1 1 IMC 14 10 6 3 2 1 1 1 1 1 1 RMC 13 9 6 3 2
