Can a 230 Volt AC be used in 220 Volt system?

Answer 1

Normally, yes. Most of the times, the 230 volt will be transformed down a number of times for much lower operating voltages. The extra 10 volt divided by that number is usually negligible. Actually, the voltage fluctuates quite a lot, and your equipment is build with this in mind. The old 220 standard was ± 10%, where 230 is well below the upper limit.

The higher voltages we use (230 V and up) is for transportation of power. High voltage

at a constant effect means fewer amperes, which means (a lot) less loss in transmission lines.

The 230 volt is a compromise between the Britain (240) and continental Europe (220)

when the two power grids were united.

Answer 2

What exactly is this question asking?

Is it asking about an Air Conditioner Unit that has been manufactured to operate in the US or Canada or similar countries which use 220 - 240 Volt 60 Hz household power supplies?

If so, it should work fine on those supplies.Note: in the US, Canada, and other countries using similar 60 Hz supplies, circuits for lighting and low-power appliances run at 120 volts plus or minus 10% in which case the voltage range could be from 108 Volts to 132 Volts.

All new buildings using this system in fact get 240 Volts plus or minus 10%, split into two 120 Volt "hot" wires (often called "legs") with a common Neutral wire. Major appliances, such as clothes driers, kitchen ranges, large air conditioning units, etc. are now manufactured to be connected to that kind of 240 V supply.

An informal, but more accurate, description of such a supply is:

A "-120V / Neutral / +120V" supply.

Or is this question asking if a 230 volt 50 Hz European appliance can be used on a 240 volt 60 Hz outlet in the USA or Canada?

If so, see the answer to the Related Question "Can you plug a 230V 50Hz appliance into a 240V 60Hz outlet?" using the link shown below.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

Answer 3

Yes, a device rated for 230 volts AC can typically be used in a 220-volt system without issues. The minor difference in voltage should not cause any significant problems for most electronic devices or appliances.

Answer 4

No. You can only use AC in a transformer. DC will, at minimum, trip the breaker, and, at maximum, destroy the transformer or cause other damage.

Answer 5

No. They will not work correctly with DC.
