How are electrical insulating rubber gloves classified?

• A. According to color.
• B. According to size.
• C. According to voltage level.
• D. According to age.

Answer: (C)

The key idea is that electrical insulating rubber gloves are rated by the maximum voltage they can safely insulate. This voltage-based rating determines the class of the glove, and you select the class that is higher than the voltage you’ll be working with to provide a safe margin. The label on the glove will indicate its class, reflecting the approved voltage range.

Color, size, or age aren’t used to determine the protective capability. Size affects how well you can work and control the glove, color is not a formal rating, and age relates to wear and mechanical condition, not the electrical insulation rating.
