240 volts into a 220 volt machine ?

As above , Is that OK or boom fizz puff of smoke

i certainly wouldn't take my word for it and go and plug stuff in, but I thought that normally 220v and 240v were nominal labels and in reality most machines operated at around 230 with a fair degree of leeway.

I look forward to being told I'm wrong

More info, Uk nominal is 230 volts, where I am it is 236 volts average but with highs and lows.

Our place, mains exceeds 250V for minutes at a stretch on an almost daily basis.
Nothing has blown up yet ....
Everything in Europe in the last decade or two is designed to tolerate 220-240V plus some overvoltage tolerance.
Personally, I wouldn't worry about it.

It is a Canadian lathe , shows 220 volts on the machine.

Photo of the motor rating plate ?
Canada is 120v 60Hz mains as I understand, so it may be a white Canadian Oneway lathe factory fitted with a 220v motor for export. Oneway were imported into the UK for many years but no longer.
A motor rated at 50 and 60hz has some margin in it as the power is higher at 60hz. From a heat and dissipation point of view only, slightly high voltage will be offset by it being used at the lower frequency.

Make sure its not 120 volts - I thought that is the standard for Canada.

I think UK voltage is usually 230 nowadays so imo if it is 220 go ahead should be fine

No. EU standard is 230 plus a tolerance, minus another tolerance.
The tolerances are big enough to allow the UK to keep pumping 240v out of our sockets while much of continental europe pump 220v out of theirs. Only the specifications changed, not the measured voltages.

The designations here are nominal, not absolute. I took a walk around the shop and the different motor data plates are marked with 208V though 240V (110V/115V/120V for lower voltage stuff) and they all run fine on whatever the power company is supplying. The 240V won't hurt the lathe. What kind is it? A Oneway or a General?

Oneway were imported into the UK for many years but no longer.

Unfortunately, they're now sold by Hope Woodturning.
I say "unfortunately" because they're very tempting!

That's great news.
It used to be the independent tool dealer near Oxford whom I visited once just before they closed down.
Good to hear that they are available again.
It's a very cool design.

I thought Europe was nearer 220v and UK nearer 240v. But to make life easier it is just called 230V.

update - I just stuck a meter in my Swiss sockets - 231/232v.
