The neutral, [always blue now by Eu directive and has been for over 10 years that I know of], is the same potential within a few volts as earth, or ground. The legal voltage is 230v 50hz, but the tolerance is sufficient to allow 240. Neutrals are only earthed/ grounded by the poco,
not the consumer, so N is
not connected to any metal chassis in any device, full stop. British plugs to BS 1363 have a cartridge fuse to suit our ring mains, usually 13A, but smaller sizes exist. This may be the stumbling block, as these fuses in the US will be as rare as hen's teeth. Next step for Joe Muggins will be a nail!
It would work 208 or 240 across N-L. Same applies to Shuko without the fuse hassle.
As to the legality, not my dept.
