I know te supply was +10%/-6% but I thought it had eventually changed
(nominally) to +/-10%, or is it that appliances have to be designed to
accept +/-10% now?
There was a date given to change to +/- 10% spec and appliances, a
date several years ago but I'm fairly sure that any action on that
date got quietly dropped and we (and Europe) have remained on the 230
+10% -6%.
230 +/-10% is 207 to 253 and a heck of range for kit to deal with.
