Jason,
There's a 2009 Broward County interpretation that you should be able to
use for some leverage:

Obviously, it's difficult to move an 8000 pound chiller off a roof to
reroof beneath it, whereas
Hi Carl,
Your 230vac is a single wave form right?
RMS peak to zero crossing of 230v
vs our
240vac which is 2 phase wave form
RMS peak to zero crossing of 120v
Have I got this right?
thanks,

Hi William,
Just a comment on the spreadsheet.
You have made provision for Centigrade, being friendly to those outside USA.
It would be nice to have reference to wire cross sectional area in mm² as
AWG is foreign to lots of folks from outside the US who reference your site.
I must
Hi Jay,
Yes you have described our grid waveform correctly.
It is strange to me that they call yours 240V, the rationale used to
describe yours and mine are different I guess.
Your grid seems to present less volts and more current.
If this is correct then I am guessing that the
Hi Carl,
thanks and yes, I think its why they only did a 120v version here.
Another question for you there.
Its my understanding that neither of your legs is bonded to ground correct?

You are very welcome.
I'd be willing to provide a metric chart. I need some information to get
started. In the US, practices are dictated by our NEC which provides the
resistance values for standard wire gauges. By putting the values in the
Code, it gives all parties a reference and
Jay,
One leg is called Phase here, this is the hot leg.
The other is Neutral and is bonded to ground at every main distribution
board.
In theory one cannot get bitten coming into contact with the Neutral but
this can happen if there is poor earthing, or a poor connection on the
Neutral
I believe that AC systems must be grounded, if only just so lightning
protection works.
