Can you be shocked by -48volts?

Yes, it is possible to be shocked by -48 volts, as voltage alone does not determine the potential for electric shock; the current that flows through the body is what causes harm. The severity of a shock depends on several factors, including the resistance of the body, the duration of contact, and the path the current takes. While -48 volts is considered low voltage, it can still be dangerous under certain conditions, especially in wet environments or if there are other factors that lower skin resistance. Always exercise caution when working with electrical systems.
