What is the maximum use voltage for Class 3 rubber gloves for DC?

The maximum use voltage for Class 3 rubber gloves designed for direct current (DC) is indeed set at 39,750 VDC. This classification is part of the standards established by the American Society for Testing and Materials (ASTM) and the National Fire Protection Association (NFPA), which outline the performance specifications and safety standards for electrical protective equipment.

Class 3 rubber gloves are intended to protect against electrical hazards during maintenance or operation activities involving electrical systems. The voltage rating means that these gloves have been tested to withstand electrical voltage up to 39,750 volts without breaking down or allowing current to pass through to the operator.

Understanding this limit is crucial for electrical professionals who handle live circuits. It provides important guidance for selecting appropriate personal protective equipment based on the working environment and voltage levels present. Exceeding this maximum use voltage while using Class 3 gloves compromises the safety and protection they are meant to provide, increasing the risk of electrical shock or injury.
