We get single phase 240V that is delivered to most electrical sockets as split phase 120V. For dryers, stoves, ovens, air conditioners, etc, it is wired to be the full 240V.

Given how many newer electronic appliances auto-switch when presented a higher voltage, I wonder if it will become more popular to connect some wall sockets with full phase 240V. It's an easy retrofit in many cases. Kinda depends on circuit density however.
