Neutral Conductor Sizing Chart

Neutral Conductor Sizing Chart - 220.61 (a), “basic calculation”, states that a “feeder or service neutral load shall be the maximum unbalance of the load determined by this article [220]. I know that in electrical grid, neutral wire is a non current carrying conductors so its cross section area is smaller than the cross section area of the live conductors. Web how to calculate the neutral wire size of a home (department)? To prevent heating problems, this conductor is run with the ungrounded (phase) conductors as required by 250.24 (c) (1).
