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. While all data cable is ran within cable tray, about 20% or so of the fire alarm cable is sharing the same tray. The commissioning agents for the project have recently told us that this is against code, however in speaking with our fire alarm subcontractor they do not believe that to be the case -. 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. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. Technical Standards and Regulations NEC (National Electrical Code) Article 300. The. Sharing the same cable tray or conduit with data cables increases the risk of mechanical damage and impairs fire resistance.
