When using rubber insulating gloves, they must be rated for what?

Rubber insulating gloves must be rated for the voltage exposure because their primary function is to protect the user from electrical shock. Different classes of insulating gloves are designed to withstand specific voltage levels, ensuring that they provide adequate protection based on the conditions they will be used in. Utilizing gloves that are not rated for the voltage exposure can lead to serious accidents or injuries, as the gloves may not provide sufficient insulation to prevent electric shock.

The gloves are also subject to other factors, such as their physical condition and environmental considerations, but the crucial factor is the voltage level they are rated to handle. This ensures that workers are adequately protected when working on or near energized electrical equipment.
