A standardized enclosure designed to house electrical connections, typically wiring terminations or switches, safeguards individuals from accidental contact with electrical components and offers physical protection to those components. For instance, the electrical outlet in a residential dwelling is contained within such an enclosure.
The implementation of this protective measure helps prevent electrical shock and reduces the risk of fire caused by exposed wiring. Historically, these enclosures evolved from simple insulators to robust, standardized units mandated by electrical codes to ensure safety and consistency in electrical installations.
