CAUTION:
Use at least 75
o
C rated copper wire. Minimum wire size is based on full load ratings
applied to NEC Code Table 310-16. Code may require a larger AWG size than shown in this table
because of temperature, number of conductors in the conduit, or long service runs. Follow local
requirements. Branch circuit protection must be provided for the input circuits as part of the
installation.
Per NEC article 300-20(2), 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 to be sized to accommodate one neutral conductor the same size as the phase conductor and one
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. Conduit sizes can be chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW,
THW-2.
