Thanks Al,
I tried using it but with my spread sheet program it gives err.504 in the calculation.
Guess I need to buy a good program.

I’ll attach it here and wee if it goes through for everyone.  Some virus filters take these out.

I think that's a broadcast item.  At the least I want a copy.

Thanks Al

I have an Excel spreadsheet (Mil-W-5088L, Ver. 3) in which you list devices, current requirement, length of wire, bundled or unbundled, continuous or intermittent; and it will immediately tell you what wire size is appropriate.  I’d be happy to e-mail direct to you or anyone who needs it.

Oops, wrong chart.  Well, it was the right chart, but not the chart
that had the maximum run length info.  It's from a page I got from
the Nuckolls site, but I can't figure out where, so I'll just attach it.
It's only a two page file.

The first chart came out of AEC Chapter 8 - which has also has
a graph illustrating the relationships for 5, 10, & 30 degree temp
rises (page 10).

   Sorry this took me so long to find, but I knew
that I had seen a chart that shows a relationship
among current, wire size, run length, and
temperature rise.  Sure enough, it was in Bob
Nuckolls's AEC.  It's on a one page PDF file at:

http://www.aeroelectric.com/articles.html

click on the fifth entry, "pdf wire size chart".

That at least leaves only the acceptable voltage
drop as an unknown variable.
