HOLT Electricians Practice Exam

In what situation is it permissible to use lighting fixtures as a raceway for circuit conductors?

1. When fixtures are not connected

2. When designed for end-to-end assembly

3. In commercial applications only

4. For temporary installations

The correct answer is: When designed for end-to-end assembly

Using lighting fixtures as a raceway for circuit conductors is permissible when they are designed for end-to-end assembly. This means that the fixtures have been specifically engineered to allow for such an application, with built-in features that accommodate the safe and efficient passage of conductors. This design consideration ensures that the fixtures meet necessary electrical codes and safety standards, allowing for proper insulation and protection of the conductors within the fixture assembly. When fixtures are designed this way, they provide a secure and effective method for routing electrical conductors without compromising safety or functionality. Lighting fixtures that are not connected or utilized in an improper manner may not provide the necessary support for conducting electricity, which can lead to hazards. Similarly, the use of fixtures specifically for commercial applications or temporary installations does not inherently qualify them for use as raceways unless they are engineered for that purpose. Thus, the specification for end-to-end assembly is crucial to ensure adherence to safety standards and electrical codes.
