There are, They saturate at nominal voltage, but yeah, you could do it. But remember that it'll get very hot/burn up if it's ran at nominal rated current
I know this is super old but MOTs are pushed way beyond their capability inside consumer ovens to cut the cost of manufacturing and that isn't a problem since microwave don't generally run for more than 5 minutes. So using the transformers for longer than that will degrade and eventually kill it
nice that explains a lot after watching the other videos, very nice. but you do realize you can buy just about any gauge wire with good insulation so you dont have to replace it right?

I think that 5x8 core at 10000 gauss should be 1600w. Am I wrong? Cheers.
you are right, but the steel core in my country has low silicon content. So just to be on the safe side, I think only 1000W should be used.
