WebJun 10, 2015 · Yes, in many cases the NEC does allow the neutral to be smaller than the phase conductors because it is supposed to only be carrying the imbalanced portion of the load. However, the increasing prevalence of electronic loads, such as electronic lighting ballasts, makes downsizing problematic. In single-phase (2 hot wires and a neutral, with … WebThe neutral wire should be the same size as the hot wire - but the ground wire can be smaller. Normally, the ground wire carries zero current. In the event of a short (the only reason for a ground wire), it only has to carry current long enough to trip the breaker - which isn’t long enough for the wire to get very hot. 3
