RE: to Pete Komen


For my quad MOT supply, I used the typical parallel input format with the 
secondaries in series (+ to -). I also exceeded the input voltage from 
120VAC to 240VAC. I also added extra insulation to the secondary with 
(spray-on) transformer insulation!! Then I placed the whole set up in 
transformer oil.
I have yet to hook the new transformer bank up to my huge tesla 
coil....hopefully it will hold up okay.

If your thinking of hooking up your MOT's up to a 7.5KVA dry type 
distribution transformer .....it "should" be okay....oil is probably not 
needed unless to push your transformers past the 6 KV mark.
