Distance between power cable trays and fire protection cable trays
This design note adopts a 300 mm horizontal air-gap separation between primary and secondary life-safety trays on roofs, based on these regulatory requirements and established UK guidance. BS 7671:2018 +A2:2022 states: “Circuits of safety services shall be independent of other. Cable tray installation must comply with specific technical standards to ensure electrical safety, system reliability, and long-term maintainability. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. Route. Recognize electrical cable tray misuse that can lead to electric shock and arc-flash/blast events and fires caused by overheating. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers. The primary rulebook used in the safe use of cable trays is NEC Article 392. However, the cable tray may be centered directly below some. UK electrical and fire safety standards do not prescribe a fixed minimum separation distance for roof-mounted life-safety cable trays.
