I don't think this would apply to the grounded Neutral. You are breaking your current carrying conductor, not your ground. You'd still leave your Ground wire intact running out to the motor.
I might be wrong, but I don't think the NEC says you cannot open your circuit if it may have 0 potential to ground. Not all grounded conductors are grounds.
