Is the cable tray for power or electrical lighting

No, cable trays are not considered part of electrical lighting; they are support systems for electrical cables, including power, signal, and communication lines.Function of Cable TraysCable trays are structural systems used to support, protect, and organize electrical cables in commercial and industrial buildings. They provide a pathway for power distribution, control, and communication cables, allowing for easier installation, maintenance, and future modifications without the need for conduit systems or open wiring . Common types include ladder trays, ventilated trays, and solid-bottom trays, each designed to accommodate different cable types and environmental conditions .Relationship to Electrical LightingWhile cable trays may carry wiring for lighting circuits, they themselves are not classified as lighting components. They serve purely as a support and management system for cables, rather than producing or controlling light. According to the National Electrical Code (NEC), cable trays are intended exclusively for electrical conductors and cannot be used for non-electrical services such as water, air, or gas . This distinction ensures that cable trays are recognized as part of the electrical infrastructure, not the lighting system.SummaryCable trays support and organize electrical cables but do not function as lighting devices.They can carry lighting circuit cables, but their role is structural, not functional in illumination.NEC regulations confirm that cable trays are restricted to electrical conductors, reinforcing that they are not part of lighting systems . In essence, cable trays are an essential part of electrical distribution infrastructure but are separate from lighting equipment and fixtures.
