HOLT Electricians Practice Exam

Which of the following is NOT a characteristic of the flexible cords used in electrical systems?

1. They can substitute for fixed wiring

2. They should connect without transmitting tension

3. They must include a grounding conductor

4. They are intended for temporary applications

The correct answer is: They can substitute for fixed wiring

The assertion that flexible cords can substitute for fixed wiring is not accurate. Flexible cords are designed specifically for different applications where fixed wiring cannot be used. They are meant to provide power to portable devices or equipment and are not intended to be a permanent wiring solution. This distinction is crucial because fixed wiring systems are designed to meet specific codes and standards for safety and longevity, while flexible cords are used in more transient or mobile settings. The remaining characteristics highlight the importance of safety and proper use of flexible cords. Flexible cords should connect without transmitting tension to minimize wear and avoid accidental disconnection, high-stress scenarios, or damage to the cord itself. Including a grounding conductor is vital for safety, as it helps prevent electrical shock. Furthermore, flexible cords are generally meant for temporary applications; they are not built to withstand the same conditions as fixed wiring for extended periods. This understanding is essential for those working in electrical fields to ensure compliance with safety standards and proper installation practices.
