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 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.
What is 230 vac?
230 VAC refers to an alternating current (AC) electrical voltage of 230 volts. This voltage level is commonly used in many countries for residential and commercial power supply, particularly in Europe, Asia, and Africa. The "VAC" stands for "volts alternating current," indicating that the voltage fluctuates in a sinusoidal wave pattern. This standard voltage is often used to power household appliances and lighting systems.
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.
How many volts are in a UK wall socket?
230-240 It's described as 230 v for harmonisation with Europe, with a tolerance of -6% +10% to allow for the fact that the actual supply voltage in most places is 240 v, and there are no plans to change it. So 230 v is the political answer, while 240 v is the real answer.
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
What is the maximum voltage rating for a 120/240 VAC breaker?
The maximum voltage rating for a 120/240 VAC breaker is 240 volts.
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.
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.
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..
What will happen if 110 vac motor connected with 230 vac?
It will burn due excess current .
What is 235 rounded to the nearest 10?
240
What is the maximum voltage rating for the equipment that can be safely operated with a power supply of 230 VAC?
The maximum voltage rating for equipment that can be safely operated with a power supply of 230 VAC is typically around 250 volts.
What is 5x plus 10 equals 240?
240-10=5x 5x=230 230/5=46 x=46
What is halfway between 230 hundreds and 240 hundreds?
Therefore, halfway between 230 hundreds and 240 hundreds is 235 hundreds.
What is the voltage of line voltage?
It varies from country to country. In the USA it is 110 volts, in the UK it 230 volts +/- 10%/6%. In practise in the UK it is 240s volt +/- 6%, the slightly odd looking specification allows harmonisation with rest of Europe. In all these cases, the mains voltage is supplied AC (alternating current) and the voltage is given as root mean square (RMS). The peak voltage in the UK is 384 volts.
