This isn't new to 05 but here's the question:
As we read this it disallows a paralleled feeder to a sub panel (from a main dist panel) if the sets are in 2 or 3 pipes (one set per pipe). We have many panels fed by two EMT pipes that originate at a breaker in a dist panel, where each contains all the phases, a neutral and a grond. We're obviously missing something here. Maybe we aren't defining "common neutral" properly. Or maybe we have a lot of illegal panels.
Your input is appreciated.
