What is the AC retest voltage for Class 1 rubber gloves?

The correct answer regarding the AC retest voltage for Class 1 rubber gloves is 10,000 VAC. This voltage is established based on industry standards for testing the integrity and safety of insulated rubber gloves used by electrical workers. Class 1 gloves are rated for use at voltages up to 7,500 volts, thus the retest voltage is set higher to ensure that the gloves can provide adequate protection even above their maximum rated use.

This practice is critical because it helps confirm that the gloves have not experienced any degradation that might compromise their insulating properties. The ac retest voltage is significantly higher than the operational voltage to ensure a substantial safety margin, providing confidence that the gloves can withstand surges or unexpected voltages that may occur in an electrical environment.

The other options listed do not align with the accepted standards for Class 1 insulation gloves. While other classes of gloves may have different retest voltages, Class 1 specifically requires the 10,000 VAC testing protocol to ensure compliance and safety in various electrical tasks.
