<div dir="ltr">Hi William,<div><br></div><div>These are 120/240 systems. These are multi-wire branch circuits, but the load pairings are uncommon. For example, on the last hybrid we did, we found that a heat tape circuit and garage lights shared a neutral. The garage lights were on the opposite side of the home as the heat tape circuit. They must have saved 30' of #10 wire by sharing this neutral. We wanted the garage lights on the critical load panel but not the heat tape circuit. We ended up keeping the garage lights out of the critical load panel. I think that there is no code-compliant way to do this (besides rewiring) because of the shared raceway requirement.</div>

If it is 120 only and if your shared neutrals are part of a multi-wire branch circuit, you have problems. The only solution I know of is to combine the circuits so they are on the same phase and share the same OCPD. Otherwise it’s time to rewire.<u></u><u></u></span></p>
