And on my MOT I found the following:
class 220
What class is my transformer?
Class 220 ;) So the wire should stand up to 220 deg.C.
I looked again at my "Class 200" MOT. It has a thermal cutout switch in a
plastic holder clamped to the secondary coil, that as far as I can tell
opens at 140 deg.C. So there is another data point...
