This conduit fill chart (Download) 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
