UPS INSTALLATION PLAN AND UNPACKINGEaton 9395 UPS (450–825 kVA) Installation and Operation Manual 164201725 Rev 4 www.eaton.com/powerquality3-22Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). SeeTable 3‐15 for conduit requirements.Per NEC article 300, 3(B)(1), all three‐phase conductors must be run in the sameconduit. Neutral and ground must be run in the same conduit as the phaseconductors.Conduit is sized to accommodate one neutral conductor the same size as the phaseconductor and one ground conductor sized in accordance with NEC Table 250.122.Conduit sizes listed are for copper wiring only.Table 3‐15.
