What is the voltage rating for class 0 rubber protective equipment?

• A. Between 200 and 600
• B. Between 600 and 1,000
• C. Between 1,000 and 1,500
• D. Above 1,500

Answer: (B)

Voltage rating shows the maximum voltage the insulating PPE can safely withstand. For class 0 rubber protective equipment, the limit is up to about 1,000 V AC. So the appropriate range is between 600 and 1,000 volts. This class is intended for lower‑voltage work, and higher classes are used for higher voltages; ranges outside 600–1,000 V would not match the protection level class 0 provides.
