WIRING FOR CIRCUITS OF OVER 600 VOLTS
WIRING FOR CIRCUITS OF OVER 600 VOLTS404. For wiring circuits operating at more than 600 V, the conductors must have an insulation sufficient for the particular voltage employed. The aboveground conductors must be installed in rigid or intermediate metal conduit, in rigid nonmetallic conduit, in electrical metallic tubing, as busways, in cable trays, as busways, as cablebus, in other identified raceways, or in open runs of metal-clad cable suitable for the use and purpose, except that in locations accessible to qualified persons only, open runs of Type MV cable, bare conductors, and bare busbars may also be used. Open runs of braid-covered insulated conductors must have flame-retardant braid, or the braid covering must be treated with a flame-retarda…
