Support Failure: if incorrectly designed or installed, repeated cycles of thermal expansion and contraction can lead to fatigue and potential failure of the tray supports, bracketry, clamps and other
All materials expand and contract due to temperature changes. It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion.
Thermal expansion and contraction of cable trays must be accounted for through the use of expansion joints. Proper installation of expansion joints is important to prevent tearing, bending, or damage

The Cable Tray Institute is now making available our complete library of technical articles which have appeared in the Cablegram. For further assistance, contact David Richmond (NEMA Senior Program
It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion.
Installation of cable support and cable management systems must consider thermal expansion and contraction. The cable ladders & trays should be anchored at the support nearest to its midpoint
1) Cable trays need expansion joints to allow for thermal contraction and expansion due to temperature changes. The NEC requires expansion joints where necessary, while NEMA standards provide
