Essentially what this consists of is a transformer whose secondary is 240 volts with a center tap added and referenced to ground. These are the 3 wires brought into the house. Between each hot wire and neutral there is 120 volts 60 Hz. except one is 180 degrees out of phase (inverted) with the other. The 120 volt loads are supposed to be equally distributed between these two hot wires. The difference between the two hot wires is 240 volts.
If you go through the house with your meter you can find two 120 volt outlets around the kitchen whose hots are on different phases you will have 240 volts at whatever amps the lowest breaker is rated at on the 120 circuits.
The only hazzard in this is a dedicated 240 volt breaker would have both phases mechanically tied together so if it trips all power would be removed from the machine instead of it just looking like it is off. (ignore the large area EMI current loop and turn off your pacemaker )
