If you have a parallel feed in a single conduit feeding a motor and you increase the conductor size by 125% do you also need to adjust the conductor for more than 3 current carrying conductors in a conduit.

Deerwood,

You can't parallel conductors under awg 1/0 FWIW.

Keep in mind that you can use the 90 degree column for re-rating if your using 90 degree type wire.
