Each column going up and down is a different gauge of wire.

Emt pipe wire capacity.

However inch emt has a maximum fill of 0 213 which is greater than the 0 138 calculated fill. We hope to provide you with the best online conduit fill calculator as well as all relevant information regarding conduits conduit fill conduit accessories and more. Just select the conduit type and the wire insulation to get a quick table of conductor properties. The possible wire gauges go from 14 awg to 750 mcm and from conduit trade sizes of 1 2 inches to 4 inches.

Inch emt has a maximum fill of 0 122 which is too small. This online conduit fill calculator is compatible with the us national electrical code nec.
