Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See
Table 3-13 for conduit requirements.
Per NEC article 300, 3(B)(1), all three-phase conductors must be run in the same
conduit. Neutral and ground must be run in the same conduit as the phase
conductors.
Conduit is sized to accommodate one neutral conductor the same size as the phase
conductor and one ground conductor sized in accordance with NEC Table 250.122.
Conduit sizes listed are for copper wiring only.
