Neither.
Line voltage can - and often does - vary from locality to locality. In the United States, you may find a wall-voltage spec'd at anything from 110v to 120v.
The corresponding "220v" power would range from 220v to 240v.
European voltages are very similar - falling in the range of 220 to 240v.
Based on the load on the particular segment of the power-line your house is on, you can see variations of several volts - plus-or-minus - over the course of a day. 230 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of .5% on the load current. eg. Wattage load of 2400. Amps = watts/volts. 2400/230V = 10.43 amps. 2400/240V = 10 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.

What is the peak value of a household appliance that uses a 230 VAC source?
Peak value is 1.414 times the RMS voltage. On a 240 volt circuit the peak voltage is 240 x 1.414 = 339.36 volts. The peak to peak value is twice this.
How many watts does a CFL bulb use?
The answer to this is country-specific. In the United States: Residential 120 VAC. Commercial also uses 277 VAC Elsewhere in the world: 220 volts to 260 volts, most frequently 230-240 volts AC.
Can you use 230 volt appliance in a 240 volt plug socket?
230 v appliances are made to work over a range of voltages and this includes 240 v. Usually the supply voltage can vary + or - 6% and the equipment must be designed for that. In the UK the nominal voltage is 230 v with a tolerance of -6% +10% because many or most of the outlets work at 240 v in practice.
What is the use of 240 three phase delta?
240 volt delta systems were used a lot in automotive garages and small manufacturing facilities. This system works great for motor loads because of the phase to phase voltage of 240 vac, motors run better (lots of motors were manufactured to operate on 240 only) on the higher voltage compared to 208 vac. Also the availability of 120 vac on the same system was a plus, however on a delta system you have one phase with a higher voltage to ground (high leg) usually about 190 vac. You have to be careful not to use this phase in certain applications.
How 240 VAC achieved in a 120 VAC environment North America home?
By connecting two separate 120 VAC legs into one. If they are and if it comes to your home from a local utility they will be, it will add to 240. Whenever combining AC or Sine waves into one for the purpose of adding they must be in phase.
Why do you use 240 volt supply in the UK?
They don't. The UK uses 230 VAC 50 Hz.
Is an airconditioning unit labeled to run on 208 vac to 230 vac ok to run on 240 vac?
yes, UL listing requires them to work with tolerance of 10% over equipment voltage
Is a 2 pole 30 amp circuit breaker equivalent to two single pole 30 amp circuit breakers?
Yes and no. Your electric panel has two bus bars. Each supplies 120 VAC. If you measure the voltage across these two buses you get 230-240 VAC. The buses are staggered top to bottom such that each breaker, top to bottom, alternates which of the buses they connect to. A 2-pole breaker would typically be use for 230-240 VAC service, but could be used for two 120 VAC circuits. However, in the latter case if either of the 120 VAC circuits tripped, both would trip. In the case of two single pole breakers, it would depend if they were connected to each bus or the same bus. However if used for a 230-240 VAC service you would want both to trip if either side tripped. This is done by joining together the handles of each breaker stacked on above the other in panel.

Is it safe to use a 230-240 volt microwave in a country like China where the voltage is 220?
No, if it says 230-240 .. 230 is the minimum..
