How is the term "Enclosed" defined in electrical safety?

In the context of electrical safety, the term "enclosed" is defined as being surrounded by protective barriers. This definition emphasizes that an enclosed electrical component, device, or installation is designed to prevent accidental contact with live parts, thereby minimizing the risk of electrical shock or fire hazards.

Enclosed spaces are typically created using materials that provide a barrier against external elements and potential intrusions, ensuring that all electrical parts are protected. This is particularly important for maintaining safety standards in both residential and commercial electrical installations.

Understanding this definition is crucial for electrical inspectors, as it guides them in evaluating whether electrical enclosures meet safety regulations and are properly designed to protect users from hazardous conditions. The other options do not reflect the correct safety criteria for electrical enclosures, as they either mischaracterize the meaning of "enclosed" or suggest conditions that do not provide the necessary protective measures.
