What type of gloves must be worn when opening a padmount transformer?

When opening a padmount transformer, it is imperative to wear Class 2 gloves and sleeves. These gloves are specifically designed to provide protection against electrical hazards. Class 2 gloves are rated for use in situations where the voltage levels can reach up to 17,000 volts, which is critical when dealing with transformers that may still hold residual energy or be at higher voltages.

In addition to their high voltage rating, Class 2 gloves also possess insulating properties that help protect the wearer from electrical shock while working in close proximity to energized components. The sleeves complement the gloves by providing additional coverage and protection for the arms, which is particularly important in situations that require reaching into panels or equipment that may be conductive.

The other options do not meet the necessary safety criteria for this task. While Class 1 gloves provide some level of protection, they are only rated for lower voltage levels and may not be sufficient for the hazards associated with a padmount transformer. Leather gloves, while durable, do not offer adequate insulation against electrical shock. Lastly, the idea that no gloves are required goes against safety protocols established for electrical work, particularly in high-risk environments involving transformers. Using appropriate protective gear is crucial in preventing serious injuries.
