UPS Installation Plan and Unpacking
Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See Table 15 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. For 3 wire configurations when neutral is not required,
the conduit sizes suggested below may be oversized.
Conduit sizes listed are for copper wiring only.
