The most I ever got shocked with was 560Vdc @ 10mA I know it was 10mA because it popped the safety breaker on the lab power supply. I was testing a clamp circuit for a high power solid state RF matching network. I had been so careful the whole time using only one hand, but I got complacent for one second and BOOM, hand-torso-hand circuit.

It felt like I got kicked in the chest. Was sore for a few days after.

So lucky I was using the lab supply with a good breaker.
