In EU you're supposed to have 230V +/- 6% in your outlet.

The way this was arrived at was:

A lot of europe used 220V +/- 10% = [198..242] V

Brittain used 240V +/- 10% = [216..264] V

Take the average of the two, and use the low max and high min as limits

QED:  230V +/- 6% = [216..244]

Never attribute to malice what can adequately be explained by incompetence.
