- After some research I found some reasoning behind the voltage range:
- 1500V is sufficient to destroy the somatic nervous system, which is responsible for consciousness and feeling of pain. After applying the voltage, within 4ms the subject becomes unconscious faster than the nervous system can register pain. The autonomic nervous system (which is responsible for basic functions such as breathing and heartbeat) requires >2000 volts to stop the heart. Allegedly, 20% is added to "be sure". Furthermore, after voltage is applied and the body saturates, there is a 10% voltage drop that varies based on the electrode resistance and the body resistance. It was also noted that the current should be below 6A to prevent burning, since that is not the goal.
- Fred A. Leuchter Associates, Inc., which made these devices seems to be the only company in US, however, the owner had no formal engineering experience and was dropped as a manufacturer, so it is unclear whether these numbers are accurate and make sense at all.
If this is accurate, it seems that properties of the human body are the primary drivers of design choices, and not safety concerns.

- If anyone has any more information regarding the accuracy of this, please do share.
- I feel that I also have to say that my interest in this is purely out of curiosity, and I do not plan to build one or sit in one. From the perspective the question is asked, this is an electrical appliance that has specs, and the reasoning behind these specs needs clarification.
