Neutral Required for New Service?

[sketchy]

As the title says, would a neutral be required for a new residential service containing only straight 240v loads? This would be for off peak loads or PV where the inverters don't need a neutral. If yes can someone direct me to the code section?

Neutral only to main, EGC only to load.

Here is how I explain it in my classes.
On the load side of the service there is a white wire and green wire. On the line side of the service, the white wire has an imaginary green stripe (since they are connected by the SBJ) If there is a line to case fault, the service neutral returns the current to the source (transformer), and back to the OCPD, which should open. With out a neutral, the line to case fault won't clear.
