Cable Tray Technical Guide A practical guide to product selection and installation This guide for engineers and installers has been developed by ABB as a practical reference regarding cable tray
A bare copper equipment grounding conductor should not be placed in an aluminum cable tray due to the potential for electrolytic corrosion of the aluminum cable tray in a moist environment. For such
It is possible to use cable trays as grounding conductor equipment. In accordance with National Electrical Code (NEC) Article 392 “Cable trays” first determine the Maximum Fuse Ampere Rating or
Adding chrome (±13%) to the iron creates a certain sheen and the metal becomes more corrosion-resistant. The advantage, compared to other protective coatings,
To avoid transverse bending at higher loads, a joint plate must be used for tray widths of 400 mm or more in the joint area of the cable trays that are to be connected.
The connecting plates and bolt ends (nuts) must be on the outside of the tray. (Diagram D.8) Tighten the rib-shanked bolts to draw bolt head flush with the inside of the siderail (20-27 ft/lbs).
Instead of large conduits, cable channel may be used very effectively to support cable drops from the cable tray run to the equipment or device being serviced and is ideal for cable tray runs involving a
For ladder or ventilated trough trays, the diameter of all cables 4/0 and larger must be added together, and the total must not exceed the inside width of the cable tray.
Cable tray installed in a hazardous location must contain only those cables that are appropriate for this type of environment as defined in Chapter 5 of the NEC.
