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 is ran within cable tray, about 20% or so of the fire alarm cable is sharing the same tray. As well as meeting minimum bend radii.

Correction factor for cables inside cable trays

There are four correction factors in the BS 7671 cable sizing methodology: Ca for ambient temperature, Cg for grouping (multiple circuits installed together), Ci for thermal insulation, and Cf for semi-enclosed fuses. Each factor is a decimal value less than or equal to 1. Except. 1 The correction factor formula is It = In / (Ca x Cg x Ci x Cf) — you must calculate the tabulated current rating before selecting a cable from BS 7671 Appendix 4. Single and three- conductor 600 V and 5 KV cables #4 AWG and larger are routed in power trays in a single layer with 3/8" minimum spacing between cables. A cable depth of 1" was used for cable trays consisting of a single. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
