What does "dead front" mean in electrical panels?

• A. Panels that are easily accessible
• B. Panels with no exposed live parts
• C. Panels that are fused for greater safety
• D. Panels that are disconnected from the main supply

Answer: (B)

The term "dead front" refers to panels that are designed to have no exposed live parts, making them safer for operation and maintenance. This characteristic is critical in reducing the risk of accidental electrical shock for personnel working on or around the panel. When a panel is labeled as dead front, it implies that all live components are enclosed within the panel, and individuals can safely touch the front surface without the risk of contacting live electrical parts. In addition to enhancing safety, this design is in compliance with safety standards and regulations that dictate how electrical installations should be constructed to minimize hazards. By ensuring there are no exposed live components, the risk of electrical accidents is significantly lowered, which is essential in any electrical installation or maintenance scenario. The use of dead front designs is a common practice in residential, commercial, and industrial electrical systems.
