Subject: RE: Multi branch circuits and NEC

Yes you can share a neutral between 2 circuits as long as you connect the 2 phase wires to a 240 volt breaker or tie the handles together on 2 adjacent 120 Volt breakers. This forces 2 things to happen:

1. That when you turn off the power, both circuits are dead

2. You do not overload the neutral because the 240 volt breaker keeps the 2 phase wires on different legs of the single phase system which cancels the neutral current.
