What must be ensured for service conductors passing over roofs according to safety regulations?

For service conductors passing over roofs, ensuring that they are secured is essential for a few key reasons. Securing the conductors helps prevent movement or damage due to wind, weather, or any activities on the roof, which could cause wear and potential hazards. Loose conductors might sag or pull away from their support, leading to dangerous situations such as contact with other structures or accidental disconnection.

While insulation, compliance with local codes, and avoiding obstruction of pathways are all important considerations in the overall installation and maintenance of electrical systems, the primary focus concerning conductors on roofs is ensuring they are properly secured. This is critical not only for the integrity of the electrical service but also for the safety of individuals who may work on or around the roofing area. Proper securing measures, such as using cable ties, brackets, or other means of attachment, help maintain safety and reliability of the service conductors.
