WebClass I power supplies protect the user through at least one layer of basic insulation first. It then uses a ground wire chassis — a grounding connection usually on the casing of the source — that grounds the hazardous voltage before it reaches the user should the basic insulation fail. A safety ground is a requirement for all Class I devices. WebThere 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 charged to a voltage below 48 V is fairly safe.
