While international programs such as CHRISTIFIRE and PRISME have contributed to our understanding through various experimental campaigns, the complexity of the phenomena and the multitude of boundary conditions affecting cable tray scenarios necessitate further experimental analysis. The objective of the study was to provide insights into the configuration factors influencing fire spread in cable trays. Through a series of controlled laboratory experiments, a set of cable tray configurations were analysed. Our results revealed critical issues influencing fire propagation and indicated like the number of cables per trays and the number of trays.}, organization = {The authors acknowledge the Nuclear Safety Council for the co-financing of the project "Metodologías avanzadas de análisis y simulación de escenarios de incendios en centrales nucleares" and for the research project SUBV-18/2022 “NUCLEVS - Validación, calibración y aplicación de modelos de propagación de incendios en escenarios reales de Centrales Nucleares.
