What is the maximum voltage for Class 4 gloves?

• A. Up to 500 volts
• B. Up to 1000 volts
• C. Up to 26500 volts
• D. Up to 36000 volts

Answer: (D)

Insulating rubber gloves are rated by class to indicate how much voltage they can safely withstand. A higher class means higher voltage protection. Class 4 gloves are the highest rating and are approved for use up to 36,000 volts (AC). That’s why the maximum voltage for Class 4 gloves is 36,000 volts. The lower classes protect less voltage—for example, Class 3 up to about 26,500 V, Class 1 up to about 1,000 V, and Class 0 up to about 500 V—so they’re not suitable for higher-voltage work. When selecting gloves, always choose a class that exceeds the system voltage plus a safety margin and follow proper inspection and testing requirements.
