What does the term "Guarded" mean in the context of electrical safety?

In the context of electrical safety, the term "Guarded" refers to being enclosed or protected in a way that minimizes the risk of accidental contact or exposure to electrical components. This is critical in ensuring safety, as it prevents unauthorized or unintentional interaction with live parts that could result in electrical shock or other hazards.

By using physical barriers, guards, or protective enclosures, the design mitigates potential dangers. This could involve items such as covers on electrical panels, shielding for wiring, or other measures that ensure that hazardous parts are not accessible unless specifically intended to be interacted with under safe conditions.

In this context, the other options are not aligned with the established meaning of "guarded." For example, having something completely open for maintenance would not provide the protections necessary for safety and could lead to increased risks. Similarly, designating something for high voltage applications does not inherently convey safety measures without appropriate guarding. Lastly, accessibility only by trained professionals, while potentially increasing safety, does not address the fundamental concept of guarding as a preventative measure against hazards.
