Yeah that is the ticket, nice diagram. Avoids both a neutral (assuming 3 wire is needed) and an egc - just two wires, one of them a grounded conductor. That is what I have at my house, 1900 feet, 2400 volts. I find it odd they still have that "rebonding" exception for sds despite getting rid of it for feeders.

Yes, it really is kind of an elegant solution. And as you point out, works for higher voltages too. I've had some well trained NEC folks raise an eyebrow at first glace of this but after a little thought seem to come around.

It is a great solution.

I just wishwe knew the actual details of the problem.

Hard to pick a solution without them.

Until OP defines parameters, I give up.
