Sunday afternoon, 4:15pm and the line is reading 237V at the moment, which is about normal. It will probably sag a little over the next couple of hours as ranges etc. come into use, although not as much as during the week. A lot of people cook their main meal at lunchtime on a Sunday, so 12-1pm time is usually a low.
Interesting on the Irish fuse colors. The U.K. standard for many years has been:
5A = white
15A = blue
20A = yellow
30A = red
(Substitute 6/16/32 for 5/15/30 for the newer MCBs.)
