An enclosure is required to prevent accidental contact with energized parts where there are bare terminals. This applies to which equipment?

Enclosures protect people from touching live parts by keeping exposed energised terminals out of reach. Transformers, switches, and motor controllers often have accessible bare terminals or conductors that could be touched during installation or servicing, so enclosing them is essential to prevent accidental contact. Lighting fixtures usually have their live parts housed within the fixture, and circuit breakers are already inside protective housings designed for safe touch; ground rods aren’t energised parts. Therefore, the requirement applies to transformers, switches, and motor controllers.
