Does your DVM read true RMS?  310 x .707 = 219.17.  I suspect not.  That
looks like a peak reading of standard two leg 220 V.  I don't remember
the power arrangements in HK (two phase, three phase, whatever) and it
has likely changed a lot since I last lived there in the early 70s.
Does "one country, two systems" apply to AC power as well?

Basil, are you sorted?  Inquiring minds want to know.  

Maybe it was in NZ that they used 250 V RMS all those years ago, or Fiji
or somewhere else.  Any Kiwis around?
