Table 3-7. Power Cable Conduit Recommendations For The Eaton 93Pm-100-1 And Eaton 93Pm-100-2 (N+1) - Eaton 93PM Installation And Operation Manual

UPS Installation Plan and Unpacking
Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See Table 3-7 or Table 3-8 for
conduit recommendations.
Per NEC article 300, 3(B), all three-phase conductors must be run in the same conduit. A ground wire must be
run 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 with
NEC Table 250.122.
Conduit is sized to accommodate one ground conductor per conduit, sized in accordance with
NEC Table 250.122.
Conduit sizes listed are for copper wiring only.
