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, number of
conductors in the conduit, or long service runs. Wire lengths should be the same size. Follow local requirements.
2
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.
3
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.
Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.
