You could isolate the cases of the two NST's from each other and ground, and then they would end up 5 or more KV above ground on each case. The problem is that the insulation on the secondary is made to handle these voltages, but the insulation of the primary is not. So instead of burning up a secondary winding, it will end up arcing over internally between the case that is on the center tap of the secondary, and the primary which is grounded. The result will be a shorted primary. > > Magnetism and flux lines, and all the internal happening within > transformers is something that few of us master or understand. > > My thoughts are that many devices, including the transformers are a > "compromise in design".

If you double voltage by running a 120 VAC transformer from the 240 VAC output of a step up transformer you will run into at least 3 problems. First if the second transformer is a HV transformer such as a NST, then the secondary will break down due to the voltages being way over the design limit. Second the leakage flux of the primary is designed to not saturate the core at 120 will most like saturate the core at 240, resulting in an extremely high primary current burning it out. Third, if neither of these got you, then the dissipation of the transformer would go up by 4:1 minimum, resulting in heat related failure. > > > Just called an electrical contractor friend.

Be careful, I have been bit at least 3 or 4 times by mine, the blasted secondary voltage will jump an inch or more to your hand if nor careful. You don't have to touch it.
