How many categories of electrical PPE are there?

There are generally four primary categories of electrical personal protective equipment (PPE), classified based on the level of protection they provide against electrical hazards. These categories range from Category 0, which offers minimal protection, to Category 4, which provides the highest level of protection against arc flash and electrical shock. Each category specifies the minimum arc rating and the types of PPE that should be used, including items like gloves, face shields, and clothing. The classification helps ensure that workers are adequately protected in various electrical work environments.
