I think what he meant was that the electrician could not legally wire a 
120V duplex receptacle for 240V. And he is correct about that -- no 240V 
to a 120V receptacle.

But from what I learned online, an electrician COULD install a special 
120V receptacle that is rated for 30 amps (regular household receptacles 
are rated for 20A), and wire that 120V circuit from a 30A breaker with 
#10 wire. That would be a single run to a single receptacle, and would 
carry 120V, not 240V.

So if you want to run a KPA1500 from 120V, tell the electrician the 
current draw at 120V, and ask him about running a 30A 120V circuit to a 
30A receptacle.
