How should cables be secured when installed in a building structure?

Cables should be secured at intervals not exceeding 4.5 feet to ensure safety and compliance with codes. This requirement helps prevent damage to the cable by minimizing movement and stress, which can occur if cables are left unsupported over longer spans. Proper securing also reduces the risk of tripping hazards and potential electrical hazards that can arise from improperly installed cables.

This standard is in line with the National Electrical Code (NEC) requirements, which aim to promote safe electrical installations. By maintaining this maximum distance for securing cables, installations can achieve better organization, ease of maintenance, and overall safety within the structure.
