In order to determine the max power before saturation you will need the cross sectional area of the central leg of the transformer . 

then use this equation 
VA Rating = ((Core Cross section area (sq in))/0.16)^2 
hope this helps

Subject: [TCML] High current MOT suggestions‏ 


This will be my first high current MOT. I had a friend send me a large 
old core, which is one giant E and l, no 180 flipping between each 
layer. Guessing most of you have done this, I was wondering whats the 
best way to go, to get the most power out of this MOT just to use for 
melting stuff with high current. Like, How many turns should I be 
using? And any idea for size? I have 4awg laying around, but I have 
heated it up a bit using like 6 turns. 

Core dimensions: 
5.33" wide 
2.13" deep 
4.45" tall 

Spacing in the core for secondary 
0.86" wide 
1.44" tall
