yes the nominal voltage in the UK is 230v but can fluctuate between 220v and 250v so yes
No.
Yes, 220 volts is in the same voltage classification as 230 volts.
Because its designed to operate at 230-460, not 120-208.
It means that, to operate at its rated power, the appliance must be provided with a 230-V supply.
Yes, but the motor's horsepower rating will not be reached.
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.
no
no
No totally different
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
Different system, US uses 110 volt. I think India uses 230 or 240 volt.
