Voltage is only an external factor that causes electric shock. (burns are another situation. )
The discharge voltage of electric batons is as high as tens of thousands of volts, which will discharge instantly and will not kill people;
If both hands are connected to 36VAC power supply, if the current reaches 1mA and continues, it will also cause life-threatening.
The magnitude of electric shock current is related to voltage, contact resistance and human body resistance, and the harm to people is also closely related to the path through the human body (the most dangerous thing is to flow through the heart).
Therefore, the common terminal leakage protector requires that the action current is not more than 30mA (or less than 15mA) and the action time is not more than 0.1s..
