yes the nominal voltage in the UK is 230v but can fluctuate between 220v and 250v so yes
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, you can use a 230 volt device on a 240 volt supply.
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.
Yes. They're essentially the same as 110-115-120 are the same. The power that comes into your house is 240V, but by the time it's transferred through wires and breakers and outlets, it drops to about 220-230V. So anything between 220-230-and-240 is the same thing.
Yes of course, almost all power tools in Canada are 110 v. Only a few are 230/240.
A 400/230-V three-phase generator hase three line terminals, together with a neutral terminal. The line voltage (i.e. the voltage between any pair of line terminals) is 400 V, while the phase voltage (i.e. the voltage between any line terminal and the neutral terminal) is 230 V.
Yes, it is 59.
Yes.
Yes.
Yes if the house supply is 220-240 volts. The required voltage range should be printed somewhere on the fan.
yes, UL listing requires them to work with tolerance of 10% over equipment voltage
