2 HOW TO SELECT CABLE TRAY 1. MATERIAL AND FINISH CODE Tray is offered in a variety of material types and finishes - aluminum, steel, stainless steel, paint ready. Refer to the material and finishes pages for more detail. Consideration should be given to environmental concerns, cost and application. 2. TRAY LOAD RATING CLASS The table to the right is the CSA load/span class designation. The classes are C1, D1, and E and you will note that the maximum load rating varies depending on the class and support spacing. Note: C,D and E are the conventional CSA designations. 8A / B/C, 12A / B/C, 16A / B/C AND 20A / B/C are the traditional NEMA designations. It is important to consider the load your cable tray will endure. Consider the following when calculating the load: cable weight, snow, ice and wind. 3. STYLES OF TRAY There are three different styles of cable tray: Ladder / Ventilated / Solid LOAD / SPAN CLASS DESIGNATION (CSA C22.2 # ) Span m (ft) Load kg/m 2.4(8) 3.0(10) 3.7(12) 4.9(16) 6.0(20) (lb/ft) 37 (25) A 67 (45) D 74 (50) 8A 12A 16A 20A 97 (65) C 112 (75) 8B 12B 16B E 149 (100) 8C 12C 16C 20C 179 (120) D 299 (200) E CODE cable tray systems are manufactured to conform to the standard load classes of CSA as follows: CSA Class Designation CODE Designation Side Rail Height Rated Load (Kg / m) Rated Span (m) C1 C C D1 D D3m D E E SELECT TRAY SIZE WIDTH E AND HEIGHT There are different widths and heights of cable tray and what you require will depend on number, size, and weight of the cables in the tray. CODE standard widths are available in 15cm, 30cm, 45cm, 60cm, 75cm, and 90cm. Height is available for the siderail as follows: C1-102mm (4 ) D1, D3m & E1 = 115mm (4 1/2) C6, D6, E6 = 150mm (6 ) 5. FITTINGS Cable tray fittings are designed to change the size or direction of the cable tray. One must consider the Tel:

3 HOW TO SELECT CABLE TRAY radius of the bend, whether vertical or horizontal. Standard radius are available in 30cm, 60cm, 90cm. Custom sizes can be factory ordered. Fittings are also used for angle situations and are available in 30, 45, 60, and CONSIDER THERMAL EXPANSION & CONTRACTION A cable tray my be affected by thermal expansion and contraction, which must be taken into account during installation. To determine the number of expansion splice plates you need, decide the length of the straight cable tray runs and the total difference between the minimum winter and maximum summer temerpatures. To function properly, expansion splice plates require accurate gap settings between trays. Reference: NEMA VE National Electrical Manufactures Association Expansion Splice Plates 7. CONSIDER ELECTRICAL GROUNDING CAPACITY The National Electrical Code, Article allows cable tray to be used as an equipment conductor. It is important to note that cable tray is not designed to support personnel. CODE tray is a mechanical support system for cables and is not to be used as a walkway, lifting apparatus or ladder. The use should display warnings to prevent the use of cable tray for purposes other than its original intent Tel:

5 MATERIAL - DESCRIPTIONS ALUMINUM STEEL (PRE-GALVANIZED) STAINLESS STEEL Aluminum Steel (Pre-Galvanized) Stainless Steel Paint Ready Aluminum cable trays are fabricated from structural grade copper free (marine grade) aluminum extrusions. Aluminum s excellent corrosion resistance is due to its ability to form an aluminum oxide film that when scratched or cut, reforms the original protective film. Aluminum has excellent resistance to weathering in most outdoor applications. Aluminum cable trays can perform indefinitely, with little or no degradation over time, making it ideal for many wet environments. The resistance to chemicals, indoor and outdoor, can best be determined by tests conducted by the user with exposure to the specific conditions for which it is intended. Pre-galvanized steel, is produced in a rolling mill by passing steel coils through molten zinc. These coils are then slit to size and fabricated. Fabricated by roll forming, shearing, punching or forming to produce cable tray. Using structural quality steel assures that the material will meet the minimum yield and tensile strengths of applicable ASTM standards. The corrosion resistance of steel varies widely with coating and alloy. The pure zinc (galvanized) coating exhibits a high degree of galvanie protection to exposed steel such as at sheared edges. Stainless steel cable trays are fabricated AISI Type 304 or AISI Type 316/316L stainless steel. Both are non-magnetic and belong to the group called austenitic stainless steels. Like carbon steel, they exhibit increased strength when cold worked by roll-forming or bending. Galvanneal steel is produced in a rolling mill by passing through molten zinc directly above coating bath at 1000 F F. The final coating is with an alloy coating of 90% zinc and 10% iron. Galvanneal is used in applications to allow for ease of painting and improved coating adhesion. Galvanneal coating is very hard and not easily scratched during handling. The product can be stretched and drawn with proper manufacturing techniques. Galvanneal coating is about 10% less galvanically active in most environments because it contains 10% iron. Specific needs of the application and corrosion performance requirements tend to dictate which type of coating will perform best. Typical application: indoor & outdoor. Typical application: chemical, refrigeration, paper and food applications. Typical application: indoor, low thermal expansion, & cost effective. PAINT READY Typical application: Indoor, astetic-open ceiling. 209 Tel:

6 CABLE TRAY RAIL PROFILES - DESCRIPTION ALUMINUM CODE offers a variety of rail heights and weight loads to meet all in field applciations. I-beam construction used in the design of side rails ensure maximum transverse and longitudinal strength. Extruded aluminum ensure smooth edges, providing protection for cables. CODE cable tray systems are manufactured to conform to the standard load classes of CSA as follows: CSA Class Designation CODE Designation Side Rail Height mm in Rated Load (Kg / m) Rated Span (m) C1 C C D1 D / D3m / D E E / ALUMINUM LADDER TRAY E C D D3m D6 102mm 115mm 115mm 150mm C6 E E mm I-beam side rail design - maximize strength-to-weight ratio - smooth edges 2 Welding bead - positive rung lock - added material dispereses heat 3 Bottom flange inside - positive rung support 115mm 150mm Tel:

7 STRUCTURAL DESIGN DESIGN CODE cable tray and fittings are manufactured to CSA standard C22.2 Nn (latest version) from designs offering unprecedented attention to detail and ease of installation. All CODE designs are symmetrical, achieving maximum strength from minimum mass and feature reinforcing ribs on the side rail for strength. In addition, CODE side rails combined with the low profile rung design, offer the greatest usable inside height available in the industry. CODE unique SPYDERLOK connector requires only four fasteners per tray. No bolts or washers are required. The speed with which SPYDERLOK can be installed reduces labour costs over competitive coupling devices and ensures swift installation of tray and fittings, while providing continuity of side rail alignment and strength. In short, CODE s careful designs have been engineered from improvements and input from the industry and on exceeding all existing specifications. CONSTRUCTION The I-Beam configuration used in the design of side rails for CODE Aluminum Tray ensures maximum transverse and longitudinal strength. In ladder and ventilated designs, rung spacing is uniform both between rungs and between sections. Steel Tray side rails and rungs are continuously roll formed for added strength and to ensure smooth edges to protect cables. Our steel rungs are slotted to accommodate pipe and cable clamps. All CODE cable tray and fittings ensure optimal strength and bonding characteristics by means of welding. Metal Inert Gas (M.I.G.) welding is a semiautomatic process using inert-gas shroud over a consumable wire electrode which transfers current to melt the base material. A filler metal is also added for reinforcement. CODE cable trays offer superior welding strength because our rungs are welded on both the front as well as the back of the rungs. This is unique to CODE tray and adds additional strength to every piece of CODE tray. Our side rails and rungs are designed to allow users to attach a UC clamp without drilling or tapping the side rail. SMOOTH EDGES All aspects of both tray and rungs feature rounded edges and flat smooth surfaces to prevent damage when in contact with cables. FUTURE EXPANSION REQUIREMENTS Easily add cables to an existing system with barrier tray. Future expansion should always be considered when selecting a cable tray, and allowance should be made for additional fill area and load capacity. A minimum of 50% expansion allowance is recommended. SPACE LIMITATIONS Any obstacles which could interfere with a cable tray installation should be considered when selecting a cable tray width and height. Adequate clearances should be allowed for installation of supports and for cable accessibility. Note: The overall cable tray dimensions typically exceed the nominal tray width and loading depth. Standard length is 3m (10ft) & 6m (20ft) Depth 100mm (4 ), 150mm (6 ) and custom SPECIAL ORDERS CODE cable tray systems have been designed to easily accept special orders to suit the specification of your job.
