Class 0 insulated gloves provide protection up to what voltage?

• A. Up to 2,000 V
• B. Up to 1,000 V
• C. Up to 1,500 V
• D. Up to 500 V

Answer: (B)

Classifications for insulating gloves are tied to the maximum voltage they are designed to withstand. Class 0 gloves are rated to provide insulation up to 1,000 volts. This means they are intended for work involving voltages up to about 1 kV, typically in AC applications, when used with appropriate leather protectors for mechanical protection. Some standards note higher DC ratings for these gloves, but the commonly cited protection level for Class 0 is up to 1,000 V AC. The other numbers don’t fit Class 0 because they’re either below the class limit (500 V) or refer to higher or different voltage ratings (1,500 V DC or 2,000 V AC) not applicable to this class.
