Powerware 9330 Installation & Operation Manual page 187

10.
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.
11.
Conduit is 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, check the size of the conduit needed to
accommodate the extra wire or size and use that conduit size in place of the conduit size
listed in table R. All 9330 products can accommodate a double size neutral.
12.
Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW,
THHW, THW-2.
