In a balanced 3 phase 4 wire wye system is there current on the neutral? I would think that the currents would cancel out.
How do you decide whether the neutral needs to be considered a "current carrying conductor" for ampacity puproses (when running with (3) phase conductors in a 4 wire system)?
What amount of nonlinear (computer equipment/inductive lighting) loads will cause you to consider the neutral a current carrying conductor?
