I'm a little confused about a 230 volt circuit. In what part of the
world does the utility supply 230v?
Continental Europe used to have 220 volts (before that it was 127 volts in
some places), the UK used to have 240 volts. Nowadays, the common voltage
is 230 volts -10% +6%.
In other words, nothing has changed. They just wrote sloppier specs.
It has changed, the voltage is now close to 230V, at least in Sweden.
I guess the sloppiness was specified to allow a gradual switch from
220/240 to 230 and still be within spec.
Do the math. The specifications allow continued use of the old
standard n each country.
If you read my comment you will see that I agree that the new spec
covers the old voltages. I do not agree with your statement that
"nothing has changed". We had 220V before and we now have 230V, so the
actual voltage has definitely changed.
