Guidelines for determining shock hazard of capacitors

So all capacitors are safe when uncharged, which is what they are when you buy them. To do harm to your body, the voltage across the capacitor''s terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common ''rule of thumb'' is that DC up to 48 Volt is considered low voltage. So a capacitor …
