Here it did change. We had 220 and they changed silently to 230 without
telling us anything. I just noticed that when I measured it I read 230
on a digital multimeter (so there was no error, and I measured in more
than one house/city), and when I bought bulbs they also said 230.
They had changed silently the contracts, too. They said we had to renew
with some unrelated excuse, and the fine print said 230.

Cheers, Carlos.

Mains was always AC wasn\'t it?
If course it wasn\'t (in the UK). Mains was AC or DC, and 120V (or
so) to 250V (or so).
Mains was always AC post WWII and probably post the advent of
consumer tube radios and IIRC was always 240VAC post WWII.
\"The Electricity (Supply) Act 1919 merged the 600-odd local
generating companies into area boards, who in turn were centralised
into the Central Electricity Board by the Electricity Supply Act
1925. That is when the voltage was standardised at 240V, and the
National Grid created.
And then the EU stole ten of our good, English volts!
Have we got them back yet?
No they didn\'t. The reference simply changed to 230V, so that 220V and
240V countries could use the same, single design of 230V equipment,
designed with a wide enough tolerance to cope with the lowest permitted
voltage on 220V systems and the highest permitted voltage on 240V
systems. The voltage supplied did not change.
