To my doubts of the data (Phelps-Dodge) I reported on magnet wire breakdown:

	I checked on the DC breakdown of armored polythermaleze coated 
magnet wire -18gauge 1.5mils of coating. Two touching or twisted wires could 
easily withstand 8KV across 3mils (2 wires) of insultion! That's at the 
LEAST a breakdown field of 2670 kV/mil. Belden claims it is actually rated 
at 3500 kV/mil.....
