0mm thickness to maximum width of 300mm. Published load safety factor is 1. Splice plates not supplied. All tests per NEMA VE-1. Splice plates not supplied. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. From an engineering standpoint, cable tray dimensions are not. us-trations without notice. In this guide, you will learn how to calculate cable tray size step by step using a practical formula, tray selection rules, and a real example. ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require additional protec eferred to support and protect numerous small. Cable support products are engineered using precise sheet steel thicknesses chosen around distinct physical load classifications.
