Expansion of cable trays and trunking

Learn how to manage thermal expansion and contraction in cable tray systems with expert tips on expansion joints, guides, and spacing to ensure long-term structural integrity. In 1993 NEC Article 318 there are no requirements for the handling of the thermal contraction and expansion of cable tray. This subject is addressed in the NEMA Standards Publication No. VE 1 “Metallic Cable Tray Systems” Section 6. Once the temperature differential. us-trations without notice.
