Fiberglass cable trays, also known as polymer alloy or FRP (Fiber Reinforced Plastic) trays, are non-conductive, which means they do not carry electrical current under normal conditions. Because of this inherent insulation, grounding is generally not required for these trays, unlike metallic trays which must be grounded to prevent shock hazards and ensure electrical continuity .
Even though grounding is not required for fiberglass trays, proper installation is still important:
While grounding is not required, if a fiberglass tray is used in combination with metallic components (like brackets, supports, or covers), those metallic parts should be grounded to maintain safety and comply with electrical codes . Additionally, always follow local codes and manufacturer recommendations, as some jurisdictions may have specific requirements for hybrid installations. In summary, fiberglass cable trays themselves do not need to be grounded, but any metallic elements associated with the installation should be properly bonded to the grounding system to ensure overall electrical safety.
The correct way to ground and bond a cabling system is to ensure all conductive components, such as cable trays,
