Under what condition can luminaires be classified as portable according to Article 410?

Luminaires can be classified as portable when they are designed for easy movement and are not permanently installed. This classification allows for flexibility in their use, enabling them to be easily relocated to different areas as needed. The inherent design of portable luminaires ensures that they can be repositioned without the need for permanent mounting or fixed electrical connections, making them ideal for temporary lighting solutions in various settings.

Being lightweight or easily disconnectable does not solely dictate a luminaire's portability. While these features can contribute to the ease of movement and use, the definitive criteria focus on their design intent, emphasizing that they should not be fixed installations. Additionally, using batteries for operation does not inherently classify a luminaire as portable; it is more about the design and installation characteristics that enable mobility. Therefore, the key factor for classification as portable luminaires lies in their non-permanent, easily movable nature.
