Can fire protection and low-voltage power cables share the same cable tray

While it is technically possible to run power and low-voltage cables in the same tray under strict conditions, segregation or shielding is strongly recommended to ensure safety, compliance, and system reliability. Correct cabling practices are fundamental to the reliability of life safety, security, and electrical systems. The principal reference standards are: BS 5839-1:2025 - Fire. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers. While all data cable ...
