Probable Effect Concentration Quotients (PECQS) Practice Test

Question: 1 / 400

Why must overhead conductors for festoon lighting be larger than a specific size?

To reduce voltage drop

To prevent fire hazards

To ensure mechanical stability

Selecting a larger size for overhead conductors in festoon lighting is crucial for ensuring mechanical stability. Overhead conductors, especially when used in outdoor environments, are subjected to various stressors such as wind, ice, and the weight of the lighting fixtures themselves. If the conductors are not sufficiently robust, they can sag or even break under these conditions, potentially leading to safety hazards or equipment failure.

While reducing voltage drop, preventing fire hazards, and complying with regulatory standards are all important considerations when designing electrical systems, the primary reason for opting for larger conductors in this context specifically relates to their ability to withstand mechanical loads and stresses without compromising safety or functionality.
