Chris, Douglas Brooks wrote an article about Preese's and Onderdonk's equations for fusing currents of wires, which was published in Printed Circuit Magazine. It can be downloaded from UltraCAD's web site at http://www.ultracad.com/fusing.pdf
Appendix F of the book that I am writing for Kluwer, Robust Electronic Design Reference, will cover the ampacity (current-carrying capacity) of wires, printed circuit board traces, busbars, etc. The manuscript is due August 1st, so I had better get back to my writing...
