Which option correctly maps the six classes of rubber protective equipment to their class tags and voltage ratings?

• A. Class 00 beige tag 500 V; Class 0 red tag 1,000 V; Class 1 white tag 7,500 V; Class 2 yellow tag 17,000 V; Class 3 green tag 26,500 V; Class 4 orange tag 36,000 V
• B. Class 00 beige tag 500 V; Class 0 red tag 3,000 V; Class 1 white tag 7,500 V; Class 2 yellow tag 17,000 V; Class 3 green tag 26,500 V; Class 4 orange tag 36,000 V
• C. Class 00 beige tag 600 V; Class 0 red tag 1,000 V; Class 1 white tag 7,500 V; Class 2 yellow tag 17,000 V; Class 3 green tag 26,500 V; Class 4 orange tag 36,000 V
• D. Class 00 beige tag 500 V; Class 0 red tag 1,000 V; Class 1 white tag 10,000 V; Class 2 yellow tag 20,000 V; Class 3 green tag 30,000 V; Class 4 orange tag 40,000 V

Answer: (A)

Understanding rubber insulating equipment hinges on knowing the voltage each class can safely withstand and recognizing that with the color-coded tags. The six classes are paired with specific voltages and colors so you can quickly verify you’re using the right protection for the job. The standard mapping is: Class 00 with a beige tag and 500 V, Class 0 with a red tag and 1,000 V, Class 1 with a white tag and 7,500 V, Class 2 with a yellow tag and 17,000 V, Class 3 with a green tag and 26,500 V, and Class 4 with an orange tag and 36,000 V. This ensures the equipment won’t break down under the circuit’s voltage, reducing the risk of shock or arc flash. Other options mix voltages or tag colors in ways that don’t match the established ratings, which could lead to using gear that isn’t safe for the actual circuit voltage.
