When contact is made with a line energized at what voltage or more can the outer skin be punctured?

The outer skin can be punctured when contact is made with a line energized at 1000 volts or more due to the effects of electrical stress. At this voltage level, the dielectric strength of various materials, including those that typically make up protective gear or machinery, can be compromised. When voltage levels reach 1000 volts, the likelihood of electrical arcing and insulation failure increases significantly, making it possible for the outer layers of skin or protective coverings to be breached, thereby exposing underlying tissues to electrical hazards.

Understanding this threshold is crucial for safety practices in power-related professions. It emphasizes the importance of adhering to safety protocols at voltages above this critical point to prevent accidents and serious injuries.
