The size of the wire is set by the maximum current it has to carry. The voltage sets the size of the insulation. In the UK a 230 v (nominal) ring-circuit supplying a set of power sockets is rated at 30 amps and uses a ring of 2.5 sq-mm cable.
No, a watt is a watt, the voltage only changes the wire size. The power company bills you based on kilowatt hours. 1hp = 746 watts, no matter what the voltage.
Yes, 220 volts is in the same voltage classification as 230 volts.
In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
Depends on the size of the circuit which you did not list.
Depends on length. The more length, the more resistance.

If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.

no
No.
The simplest way is to buy a DC power supply that plugs into 120 VAC as its power source and the output is DC at 230 VDC either fixed or variable. Make sure it can deliver the current your device requires and that you use the proper size wire for the DC connection based on the amperage.
no
No totally different
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
