Default 280V motor on 230V circuit

If you are in North America, and have 120 VAC to the outlets, what you
call 220 or 230 VAC in your home is actually 208 VAC, unless you
installed some kind of transformer to compensate.


No, that's not true. It's 240V, the transformer has a grounded center tap so
120 from either side to neutral, and 240 between the hots. You find 208V in
commercial buildings and some apartment complexes that are fed with 3 phase,
but not in a house, unless you're one of the few lucky people to have 3
phase available.


I somehow think that the vendor of the motor made an error. Having 280
VAC sounds to me very unconventional, unless this was some kind of
special installation.


It's clearly a typo and should be 208V.
