[QUOTE="Marlow Wilson, post: 24681, member: 47"] Still from my phone here... The codes apply to a variety of circumstances, against a variety of possible dangers. One such danger with mwbc's in regular wiring is that a breaker can be turned off but the neutral can still be carrying electricity for the other circuit. If you disconnect the neutral and something is turned on upstream to the still energized circuit, the upstream neutral can use your body (perhaps your left hand to right hand - across the heart) to reach the downstream neutral. You may never do this, but the code is there for a reason. [/QUOTE]
