What do the terms "exposed conductors" and "energized parts" refer to?

The terms "exposed conductors" and "energized parts" refer to components of an electrical system that can present a hazard to individuals. Specifically, exposed conductors are wires or parts of the electrical system that are not insulated or shielded, making them accessible to touch. Energized parts refer to components that carry electrical current, which can create a risk of shock or electrocution if contacted.

Understanding these terms is crucial for maintaining safety in environments where electrical work is performed. When workers are aware of what constitutes exposed conductors and energized parts, they can take proper precautions to avoid accidents. This includes wearing appropriate personal protective equipment, employing lockout/tagout procedures, and ensuring that work is performed when the system is de-energized whenever possible. The focus on safety around these terms reflects the importance of preventing electrical injuries in the workplace.
