Metal actually expands and contracts with weather change, and leaving some small gap in between tray sections is a must. When the distance between the metals is too low, the metals will push against each other and bend. It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion. 1993 NEC Section 300-7 (b) states that “Raceways shall be provided with expansion joints. The Cable Tray Institute is now making available our complete library of technical articles which have appeared in the Cablegram.

Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug.
