UPS Installation Plan and Unpacking3-20 Eaton 93PM UPS (20–100 kW, 480V – 100 kW Frame) Installation and Operation Manual P-164000227—Rev 6 www.eaton.com/powerqualityConduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See Table 3-7 or Table 3-8 forconduit recommendations.Per NEC article 300, 3(B), all three-phase conductors must be run in the same conduit. A ground wire must berun in the same conduit as the phase conductors.When running parallel wires in multiple conduits a ground wire must be run in each conduit in accordance withNEC Table 250.122.Conduit is sized to accommodate one ground conductor per conduit, sized in accordance withNEC Table 250.122.Conduit sizes listed are for copper wiring only.Table 3-7.
