What I really don't get it that some people on this forum here buy a commercial isolation transformer from a well respected company, which is designed for medical industry, but that they then still have to do their own modifications to the isolation transformer to further "improve" it.
So the people who make these modifications believe that the company who designs the isolation transformer is stupid then?
Or in other words, why aren't there any commercial isolation transformers on the market which are good enough, and which require no further modifications?
The moment you do a modification to these devices, you are entering risk zone in my opinion, and most likely you don't even have a clue of what you are doing. You are just playing around, without realizing the risks you are building into the device, with your so called "improvement".
