Does a mesh cable tray need lightning protection
Where cable tray systems contain only signal and communication circuits that operate at low energy levels, power grounding per NEC Section 318-7 is not appropriate, but cable tray grounding for lightning protection, noise, and electromagnetic interference is necessary. According to this method, conductors forming a mesh should be placed on the structure. For buildings higher than 60m, a mesh with the same size should also. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. Their open-grid design makes it easy to route, add, or modify cabling. Mesh cable trays offer an open system where cables are securely attached to the mesh, minimizing issues like condensation, moisture, and bacterial growth compared to closed trays.

Construction of Lightning Protection Grounding Module for Photovoltaic Substation
However, there are multiple methods for grounding DC systems in PV arrays. The recommended approach is to use a separate DC grounding electrode for PV arrays and frames, as this enhances protection against lightning and transient voltage. By: Thor, Electrical Engineer at Weisho Electric Co. Thor brings years of experience in substation grounding system design and installation, dedicated to delivering professional and reliable electrical safety solutions. Low flash density areas could still result in damage to utility scale PV plants. Grounding systems have to consist of meshes (20m x 20m/ 40m x 40m). This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing. Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. The lightning protection industry began in the United States when Benjamin Franklin postulated that lightning was electricity, and a metal.
