UPS INSTALLATION PLAN AND UNPACKING

Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See

Table 3-13for 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.
