    Thats easy to answer MPH...that 10V difference is how much loss there is as the power cord goes across the ditch from Oz to NZ,that way when the last kiwi leaves NZ we can turn the power off instead...hehehehe

    Ok,

    we had to have one, and he is from the 'other' state of Australia.

    I think what your are referencing to is AS/NZ2926-1987 which stated that the domestic supply voltage for Australia and our eight state was 240 VAC (+6/ -10%).

    In 2000. AS/NZ2926 was 'harmonised' with the rest of the world. the new standard is 230 VAC (+10/-6%) . The math shows the the Upper and Lower limits are the same, just the label has changed.

    In the US, the standard is 120VAC (+5/-5%), yet you will find references to 110, 115 and 117.

    and for the record, 220 and 240 VAC fall within the standard AS/NZ2926 as part of the harmonisation protocol.

    To para-phrase an ex PM of NZ, for every KIWI that returns to NZ, the collective IQ of NZ and AUS increases.

    Remember - this is just a post, not a thesis... ;-)
    Great piece.

    Did you know? "As of 2000, the mains supply voltage specified in AS 60038 is 230 V with a tolerance of +10% -6%[3]. This was done for voltage harmonisation - however 240 V is within tolerance and is commonly found."
    http://en.wikipedia.org/wiki/Mains_power_systems

    I didn't know this. I am going to go and ask Integral Energy about this

    Cheers

    I did say something about "the man". . . . I also mentioned imperial and metric. Ooooh it's a can of worms ;)
    Ugh, this year will be too busy. I'd like to buy a vowel and more time please.

    ... and I'll have you know that some of us Americans really want Metric. I'm sick of keeping 2 sets of tools around!:p

    I harken back to the old days of street racing when all you needed was a flat blade screwdriver, a vise-grips, a 9/16 wrench and some electrical tape and you could fix a Chevy... (sigh...)

    So you have fond thoughts about the 'old days' too, eh?
