What is the voltage rating for Class 4 rubber gloves?

Class 4 rubber gloves are designed for high-voltage work and are rated for use at a maximum voltage of 36 kV. This rating indicates that the gloves have been tested to withstand voltages up to 36,000 volts, making them suitable for protection while handling energized electrical equipment in environments where such high voltages are present. It's crucial for linemen and electrical workers to use gloves appropriate for the voltage level they might encounter to ensure safety and reduce the risk of electrical shock. Other options mentioned represent different classes of gloves with lower voltage ratings, thus not providing adequate protection for high-voltage applications.
