Low-voltage cable trays placed on the ground
All metallic cable trays shall be grounded as required in Article 250. The EGC is the most important conductor in an electrical system as its function is electrical. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. If you take what UL states literally, ANY cut to tray (ladder or wi e) would cause a loss of UL Classification. The Equipment Grounding Conductor is the electrical circuit's safety conductor. There are three wiring. us-trations without notice. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned. Can someone explain to me or provide a code reference that thoroughly explains the proper way to ground low voltage telecom cable tray? I'm having a hard time interpreting whether or not each section of tray whether it be a 10' or 2' section needs a split bolt connection to the ground wire.
