40 kVA model must be wired for 50 kVA. 100 kVA model must be wired for 120 kVA.
11.
Per NEC article 300-20(a), 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.
12.
Conduit is to be sized to accommodate one neutral conductor the same size as the phase
conductor and one #8 AWG ground conductor. If two neutral conductors or an oversized
neutral conductor are to be installed, size the conduit to accommodate the extra wire or
size. All Powerware 9390 products can accommodate a double-sized neutral.
