Service-entrance cables must be supported within what distance of the service head?

Service-entrance cables must be supported within 12 inches of the service head to ensure proper installation and safety standards are maintained. This requirement is in place to prevent strain and movement on the connections, which can lead to wear, damage, or potential hazards. Adequate support plays a critical role in effectively managing the weight and tension of the cables, ensuring they are secured in place and reducing the likelihood of accidental disconnection. This distance helps to ensure compliance with electrical codes and promotes safe and reliable electrical service to buildings.
