There's no particular safety concerned when you're playing with hundreds of kilovolts in a typical school. You need it when the thing you're messing with has the capability of delivering a lot of amps.
- timpattinson 4y ago415 volts on a 30A breaker, like you might find in an undergraduate electrical engineering lab, is very lethal. I'd hazard a guess that's what the OP is talking about.
- BenjiWiebe 4y ago415 volts on a 5A breaker is equally lethal, and not high-current. 1,000 Amps and 5 volts is dangerous (sort of), but not in an electrocution sense.
- throwaway9870 4y agoWhat you care about is how much charge is at that high voltage potential because current is charge/sec. Charge due to stray capacitance can be quite dangerous because if you don't know what you are doing, the amount of stray capacitance can be higher than you expect. I would be very careful doing anything with kilo-volts using a circuit, as opposed to a static charge device, such as Van de Graaff generator.
- planede 4y agoWhen you get shocked by a Van de Graaff generator, you do get high voltage, as well as high currents. The missing ingredient is time. The shock takes a very small time, so the energy delivered by the shock is very small. Skin-effect also helps.
