Wire Ampacity and Size Maximum loading for any branch circuit is 80% of rating of circuit for ampacity of wire for any load. NEC 220-2, use NEC 310-16 for ampacity. This applies to not more than 3 phase conductors in 1 conduit. Warning. Voltage Drop NEC 310-16 wire ampacity tables do not take into account voltage drop, only thermal limit.
