Conduit Fill Chart
Conduit Fill Chart
Use our conduit fill chart to determine how many electrical wires can safely fit inside different types and sizes of conduit. The table provides wire capacity information for common EMT, IMC, rigid metal, and flexible metal conduit, based on conductor size and conduit trade size.
This conduit fill chart is used to determine how many wires can be safely put into non-PVC conduit tubing or pipe. Each row going across is a different conduit size and type of metal conduit, either Electrical Metal Tubing (EMT), Intermediate Metal Conduit (IMC), Galvanized Rigid Steel Pipe (rigid metal conduit, RMC), or Flexible Metal Conduit (RMC). Each column (going up and down) is a different gauge of wire, either AWG or MCM. The results show the allowable number of wires for each size/type of conduit and wire, based on the 2020 NEC® code.
Ampacity Calculator
Simplify complex wire ampacity calculations with FRCABLE’s convenient Online Ampacity Calculator. This intuitive calculator takes the guesswork out of electrical code compliance, ensuring you select the right conductor size for your specific application.
