What is the primary reason for enclosing electrical switches and current-carrying components?

Enclosing electrical switches and current-carrying components is primarily intended to protect workers from electrical shock. When these components are not properly enclosed, there is a direct risk that workers can come into contact with live electrical parts, leading to potential injuries or fatalities. Enclosures provide a barrier that enhances safety, preventing accidental contact and reducing the likelihood of electrical hazards in the workplace.

While preventing dirt and moisture from entering, increasing equipment capacity, and avoiding damage to the equipment are also significant considerations in the design of electrical installations, the protection of personnel from electrical hazards is the foremost reason for these enclosures. Ensuring worker safety remains a top priority in any workplace where electrical components are used.
