ECN Forum Forums Code Related Discussion NEC & other Code issues 240V only in a home and NEC?

Is it anything in NEC that makes it wrong if you wire an entire house with 240 only.

Of course you may only use approved components and US standard 240V outlets.

I do not believe it is good solution but will it be OK to NEC?

As grown up in Europe, 240 is often convenient for me. Should I build a house in North America I would probably had both 120 and 240 ind all rooms if it is OK in NEC (Would that be OK?)
