Carl:<br><br>
You are very welcome. <br><br>
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 (hopefully)
avoids arguments about conflicting data.<br><br>
I downloaded the New Zealand Electrical Code of Practice (NZECP 51:2004)
and did not find in it any resistance values. Is this the correct
document to look in? Are resistance values in there and I am just
not finding them? If the values are not in the NZECP, where do
professionals in New Zealand look for the resistance values?<br><br>
There is a slight difference in resistance (impedance) between AC and DC
circuits as listed in the NEC. I used the higher values to allow
conformity in all cases. Let me know if there is a different
consideration for AC versus DC in New Zealand.<br><br>
Do you know what other Metric based nations use for determining wire
resistance values?<br><br>
Thanks in advance.<br><br>

Just a comment on the spreadsheet.<br>
<br>
You have made provision for Centigrade, being friendly to those outside
USA.<br>
<br>
It would be nice to have reference to wire cross sectional area in mm˛ as
AWG is foreign to lots of folks from outside the US who reference your
site.<br>
<br>
I must say that your making information freely available over the years
has assisted many.<br>

Thanks for the plug. The copy you have is outdated. Here is where you will find the new and improved version: <a href="http://millersolar.com/MillerSolar/Resources/_Resources.html" eudora="autourl">http://millersolar.com/MillerSolar/Resources/_Resources.html</a><br><br>
What we created in the Miller Solar wire sizing spreadsheet is an opportunity to compare the voltage drop for all common wire sizes in one view so you can evaluate the tradeoffs for various scenarios.<br><br>
Questions or comments are appreciated.<br><br>

I stumbled onto this wire sizing calculator that gives NEC qualified data. <br>
Wikipedia had a link to it.<br>
