Is UK mains 230v or 240v?

What is the difference between UK voltage and European voltage. The voltage used throughout Europe (including the UK) has been harmonised since January 2003 at a nominal 230v 50 Hz (formerly 240V in UK, 220V in the rest of Europe) but this does not mean there has been a real change in the supply.

In this regard, what is the main voltage in the UK?

Just as it was in 1960, the supply voltage to domestic properties in the UK is still nominally 240 V AC at 50 Hz, although the declared voltage in the UK is now 230V AC +10% to -6%. Historically the domestic voltage was 240 V +/-6% (and 415V 3phase), whilst continental Europe was 220V (380V 3 phase).

What is 230 volt power?
