Is it safe to run cables through cable trays in power wells

Metal cable tray systems must be grounded. This is a major part of safety. You do not want to get. Power cables are often installed on exposed metallic trays in industrial and commercial electrical systems, a widely accepted practice in these environments. Cable. In industrial settings, electrical and instrumentation (E&I) cable trays or bridge racks play a critical role in organizing and supporting power, control, and signal cables across facilities. An effective layout ensures safety, minimizes interference, reduces maintenance time, and keeps the overall. Scenario: Many power generating plants have extensive systems of cable trays. For example, sometimes the trays are lower than 8 feet above the work surface and in close proximity to where unqualified workers routinely travel and work. However, they offer limited ventilation, so they may not be ideal for high-heat applications unless heat-resistant cables are used.
