Phase rotation

Kelly Marie Angel

Hi all I think its fairly common knowledge that the phase sequence on Merseyside is different from most of the rest of the country  but what I didn't know is that South London  is also different   Blue Red Yellow apparently someone got it mixed up at battersea power station and its been that way since the 1930s is this common knowledge ? Must be very confusing when wiring up motor loads  and other phase sensitive gear its amazing to think one cock up  70 plus years ago is still having an effect now

    Interesting replies thankyou all. I'm not surprised some other country's have problems  in that respect after all some can't even maintain a steady 220 volt supply. It's obviously a lot more common than I thought  here in dorset we do at least manage to maintain a normal R Y B rotation thank hoodness
