It's an outlet wired for dryers, stoves and some large heaters.
In about 50% of the world 230 Volts is the standard household supply used for all appliances. In the other half of the world it is 110 Volts.
Yes, it can be and there is no problem at all Because most of the electrical appliances are made to work on 220v - 240v so it can also be plugged into a 240v outlet.
You would have to install a 230 volt outlet.
Anything of such voltage will be burnt if plugged in a 230v socket outlet because the voltage is too high.
I think it depends on country to country. In India, it is 220V-230V
Absolutely not.
Doesn't sound like a good idea to me.
no way because frequency cannot change
Power is multiplication of voltage and current. You need to know the load current drawing to establish the power. It is a bad idea to use 230 v adapter in 120 volts outlet
it will not run
No bell wire is not meant to be 230V.
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
