What is the maximum use voltage for Class 1 rubber gloves?

• A. 10,000 volts
• B. 7,500 volts
• C. 5,000 volts
• D. 12,500 volts

Answer: (B)

Rubber insulating gloves are categorized by class to match the voltage they can safely withstand. The class indicates the maximum use voltage for AC operation. For Class 1, the AC rating is 7,500 volts (with a DC rating of about 12,500 volts), so the highest voltage you should use Class 1 gloves with is 7,500 V. The other numbers correspond to either other classes or the DC capability, not the AC use voltage for this class. In practice, gloves are paired with leather protectors and must be tested regularly to ensure they remain intact.
