What requirement applies to electrical equipment with bare terminals?

Electrical equipment that has bare terminals poses a risk of accidental contact, which can lead to electric shock or other hazards. To mitigate this risk, the requirement for an enclosure is essential. An enclosure serves as a protective barrier, preventing unauthorized or accidental access to the bare terminals. This is particularly important in environments where personnel may come into contact with or work near the equipment.

By enclosing the terminals, the likelihood of someone inadvertently touching the live parts is significantly reduced, promoting safety compliance with the NEC (National Electrical Code) standards. Proper enclosures also help protect the equipment from dust, moisture, and other environmental factors, which can degrade performance and safety over time. Thus, implementing an enclosure for electrical equipment with bare terminals is a crucial safety measure.
