Unless you live somewhere where there's a requirement that 220 devices have
their own outlet, there's no reason you can't have more than one on the same
circuit. An N amp 220 breaker will trip when > N amps are drawn on the
circuit, same as a 120 V breaker. (There are places that require that
houshold 240 loads have a single outlet per circuit. That's silly, but the
code makers get to make the rules. )
