Dnk, it's not just the cost of wire, it's also natural resources including fuel for generation.

We literally install thousands of multi-wire circuits every year and I only know of one open neutral problem we have had in the last ten years, which had been tampered with by the particular facilities maintenance staff.

John, a dedicated grounded conductor to one ungrounded conductor is not a neutral. [Linked Image]

I have seen more open service neutrals than branch circuit or feeder neutrals by far.
