In the UK the mains voltage is 240 volts
The mains voltage is 230 volts, and the frequency is 50Hz.
Since 1998, the standard mains supply throughout Indonesia is 230 volts, 50 Hz.
220V
The standard nominal mains supply everywhere in the USA is 120 volts AC, 60 Hz.
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
You get power, which is voltage * current (so both!).
It depends on where you live, as most countries have their own standards. In the UK, for example, the nominal (named) mains voltage is 230 V, but it is allowed to vary between +10% and -6%. The nominal frequency of this voltage is 50 Hz, and this is allowed to vary between +/-1%. In North America, the standard nominal supply voltage is 120 V at 60 Hz.
