A 400-A, 3Ø main lug panel will be fed with one conduit from a 300-Amp, 3-pole breaker in a 120/208-volt, 3-ph, 4-wire panelboard. The feeder will consist of three 350 kcmil conductors (one for AØ, one for BØ, and one for CØ) plus a grounded conductor. Most of the loads are 120-volt, 1-phase and the neutral load is calculated to be 140 amps.Refer to Scenario 205.2. The smallest neutral that can be run is a ___ AWG.
