Re: 220v Chinese motor both hot leads need to be 220v?
To add, in N.A. the 120v-0-120v residential supply is derived from the secondary of a 1ph transformer, in most other parts of the world the 230v/240v is derived from one phase and a star neutral as seen on the transformer on the right.
Essentially the same result.
Countries such as China tend to show power diagrams catering to the latter, so often their instructions are confusing, also they do not always conform to earth grounding code, colours etc.
