Which type of cord should portable lamps be wired with?

1. Rigid conduit

2. Flexible cord

3. Semi-rigid cable

4. Non-flexible wire

The correct answer is: Flexible cord

Portable lamps should be wired with flexible cord to ensure the safe and effective operation of the lamp while allowing for ease of movement and adjustment. Flexible cords are designed to be movable and can withstand repeated bending and flexing, which is ideal for applications where the lamp might be repositioned frequently. Using flexible cord provides durability and flexibility, preventing damage from the normal use associated with portable lighting. Furthermore, it is constructed to prevent wear due to movement, making it suitable for the dynamic nature of portable lamps, which are often moved around in various settings. In contrast, rigid conduit is intended for permanent wiring installations, semi-rigid cable may not provide the necessary flexibility for frequent movement, and non-flexible wire lacks the adaptability required for portable applications. Therefore, flexible cord is the appropriate choice for ensuring both safety and practicality in wiring portable lamps.
