Table 3-6. Power Cable Conduit Requirements - Eaton 93PM Installation And Operation Manual

Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See Table 3-6 for conduit
requirements.
Per NEC article 300, 3(B)(1), all three-phase conductors must be run in the same conduit. Ground must be run
in the same conduit as the phase conductors.
Conduit is sized to accommodate one ground conductor sized in accordance with NEC Table 250.122.
Conduit sizes listed are for copper wiring only.
