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.

Yes, 220 volts is in the same voltage classification as 230 volts.
Yes, but a fact has to be taken into account that when a 230 volt rated bulb is used on a 120 volt system the wattage output is half of what the 230 volt bulb is rated at when it operates on 230 volt. So the dimmer will only be used to control half of the bulbs wattage which could bring the bulb down to a dull glow in full dimming position.
The question can't be answered - it has no meaning :)
My electrician says no, has to be some rewiring.
Yes, a 230-volt appliance should work fine on a 220-volt outlet in South Africa. The small difference in voltage is usually within the tolerance range of most appliances. However, it's always a good idea to check the appliance specifications to ensure compatibility and avoid any potential damage.

No. The capacitor will short out and possibly explode. On the other hand, the 440 Volt Cap can be used in a 220 Volt circuit.
Yes
There is no remedy but to plug it into a 230 circut.
No, if it says 230-240 .. 230 is the minimum..

Yes no problem.
Yes, 240 volts is a "nominal" figure, related to peak current. The actual usable voltage is in the 220 -230 range and any 220-230 volt appliance will be quite happy.

Yes. As far as in the US 220v and 240v is pretty much the same thing. People call it 220 but realistically you prob have 230-240v. Get a cheap voltage tester and check it out
