Use only 90°C-rated copper wire. Minimum wire size is based on 120/208 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, numberof conductors in the conduit, or long service runs. Follow local requirements.
2
Per NEC article 300-20(a), all three-phase conductors must be run inthe same conduit. Neutral and ground must be run in the same conduit as the
phase conductors.
3
Conduit i s 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 usethat conduit size
in place of the conduit size listed. Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.
