Can fire protection and low-voltage power cable trays be shared
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. While all data cable is ran within cable tray, about 20% or so of the fire alarm cable is sharing the same tray. YY, SY and CY cables are made to various manufacturers specifications but not governed by any National, European or International standard, hence these are not currently recognized in BS 7671:2018, Regulation 133. 1 of BS 7671:2018 requires every item of equipment to comply with the appropriate. Route Planning and Layout Principles Coordinate with Building Structure: Cable tray routing should align with architectural design, avoiding unnecessary. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers.
