What is the maximum use voltage for Class 4 rubber insulating gloves?

• A. 26,500/39,750V
• B. 36,000/54,000V
• C. 50,000/69,000V
• D. 10,000/20,000V

Answer: (B)

Class 4 rubber insulating gloves are designed for high-voltage electrical work, and the maximum use voltage for these gloves is indeed 36,000 volts for alternating current and 54,000 volts for direct current. This classification is in accordance with the standards set for electrical safety equipment, ensuring that workers are adequately protected while handling electrical systems at these voltage levels. The other options reflect different classes of rubber insulating gloves or incorrect voltage ratings for Class 4 gloves. For instance, the maximum use voltage for Class 3 gloves would be lower, typically around 26,500 volts for AC. The Class 2 gloves would have a lower voltage capacity still, reinforcing the importance of using the appropriate class for specific job requirements. Therefore, it is essential for those working in the electrical field to understand these classifications, as using gloves that are not rated for the voltage they are working with could lead to serious safety hazards.
