Class 4 rubber insulating gloves are proof-tested at what voltage?

Class 4 rubber insulating gloves are designed for high-voltage applications and are proof-tested at a voltage of 40,000 VAC. This test ensures that the gloves can withstand electrical stress and provide adequate protection against electrical shock and arc flash during electrical work. The proof testing is crucial for certifying the gloves to meet safety standards required for working with high-voltage equipment, making them a vital part of personal protective equipment for electricians and technicians in the field. Proper usage and regular inspection of these gloves are essential to ensure their effectiveness in protecting against electrical hazards.
