Thanks Nathan.  That is the company I was going to order some wire from for testing.  I suspected, as you concluded, that the insulation was capable of higher voltages than they may rate it at.  I wish they would provide 20 and 22 gauge wire.  Perhaps they would if someone would order enough!  It has to be better than the old wire with cracks in the rubber underneath the cloth weave covering.  I will call them on Monday to order various color combinations.
