Cable Tray SystemsGENERAL INFORMATION

WARNING! Cable tray should not be used as a walkway, ladder, or support for people;cable tray is a mechanical support system for cables and raceways. Using cable trays asa walkway can result in personal injury and also cause damage to the cable tray systemand installed cables.

Hazardous voltages in electrical equipment can cause severe personal injury or death. Safety related work practices,as described in NFPA 70E, Part 11 or VDE 0100, should be followed at all times.

The overall performance of a cable tray wiring system is dependent upon proper installation, including supports andcables. Non-adherence to installation and maintenance guidelines may lead to personal injury as well as damage toproperty.

Installation and proper maintenance of cable tray wiring systems should be performed only by qualified personnel.For the purposes of this guideline, a qualified installer is one who is familiar with electrical construction. In addition,the person should be :

Trained and authorized to test, energize, clear, ground, tag, and lockout circuits in accordance withestablished safety practices.

Trained in the proper care and use of protective equipment such as insulated rubber gloves, hardhats, safetyglasses or face shields, dust masks and flash resistant clothing in accordance with established safetypractices and / or local building codes.

RECEIVING AND UNLOADINGCable tray is generally bundled and shipped via motor freight on extended pallets. Accessories and smallcomponents are boxed and often skidded.

Cable tray can be shipped via LTL common carrier, trailer, or flat bed truck. LTL carriers are normally used for lessthan truckload shipments. This method of shipment is the most cost effective and offers maximum protection fromthe weather during shipment. LTL shipments should be hand unloaded unless provisions have been made with thecable tray manufacturer for forklift unloading.

Flat bed trailers are often used for full truckload shipments and / or when customers want side forklift unloading orsling unloading by crane. (Special care must be exercised to assure that the cable tray is not crushed fromimproperly locating and lifting with a sling.)

ACCEPTABLE(best) UN-ACCEPTABLE

*Except when utilizing extended forks for skidded bundles

Small to medium size orders less than 2000 ft. (600 m) are generally shipped via common carrier - LTL Service.If hand unloaded, workers should wear gloves and steel-toed footwear .

US 9


To prevent damage to cable tray, never unload from truck / trailer by chaining to bottom of the skid and draggingout of trailer.

ACCEPTABLE UN-ACCEPTABLE

Inventory all items immediately after unloading, using the manufacturers packing list. Note on the bill of lading anyshortage or shipping damage for filing freight claim.

STORAGEAluminum, Fiberglass, Stainless Steel and /or other non-metallic cable tray can be stored outside without protectivecovering. Tray should be loosely stacked, elevated off the ground, and ventilated to prevent storage stain. Ifappearance is important, cable tray should be stored indoors to prevent water or other environmental factors fromstaining or adhering to cable tray.

Hot dipped galvanized after fabrication (H.D.G.A.F.), mill galvanized or electro-galvanized cable tray must beprotected or stored in a well ventilated, dry location.

Bare steel cable tray should receive a protective coating as soon as possible to prevent surface rust.

PVC or painted cable tray should be protected and stored indoors if possible. Cable tray must be protected fromscratching and marring of finish.

Small accessories should be stored in such a manner to prevent loss or damage.

Cable tray should be stored away from high traffic areas. Cable tray should be stacked by width and type.

INSTALLATIONAttention Cable Tray Installers Cable tray system design shall comply with NEC Article 392, NEMA VE 1, IEC61537 and shall follow safe work practices as described in NFPA 70E and NEMA VE 2.

The instructions and information contained here-in are not intended to cover all details or variations in cable traysystems, nor do they account for every possible installation scenario.

It is recommended that the installation work described be performed by qualified personnel, preferrably a certifiedelectrical contractor, familiar with standard electrical construction practices, electrical equipment, and safety ofelectrical wiring systems.

US 10


Support InstallationCaution! Do not cut or drill structural building members (e.g. I-beams) without approval from the general contractor.In order to install cable tray supports, find the required elevation from the floor to the bottom of the cable tray andestablish a level line.

Cable Tray Supports

Caution! Supports for cable trays should provide strength and working load capabilities sufficient to meet the loadrequirement of the cable tray wiring system. Consideration should be given to the loads associated with future cableadditions or any other additional loads applied to the cable tray system or the cable trays support system.

Straight Section PositionAfter the supports are in place, the installation of the cable tray can begin at any place that is convenient. It is notnecessary to start at one end of the run. It is ideal to lay out the system so that splice joints fall between thesupport and the quarter point. This maximizes the rigidity of the cable tray.

To begin, place a straight section across two supports so that the ends of the section are not directly on thesupport. If the support span is equal to the length of the straight sections, bolt two pieces together for this step. As ageneral practice, avoid placing splice plates over supports or at mid-span.

Field Modifications

Cable Tray can be adapted (cut to spec in field situations). These field modifications should be made by qualifiedpersonnel only.(preferrably a certified electrical contractor)

SteelSteel cable trays are fabricated from continuous roll-formed structural quality steel. By roll-forming steel, the mechanicalproperties are increased allowing the use of a lighter gauge steel to carry the required load. This reduces the deadweight that must be carried by the supports and makes the system easier to install for the contractor. By usingstructural quality steel, NIEDAX assures that the material (steel) will meet the minimum yield and tensile strengths ofapplicable ASTM standards. All cable tray side rails, rungs and splice plates are numbered for material identificationpurposes. The corrosion resistance of steel can vary widely, depending on types of coatings and alloy used.

Stainless SteelStainless Steel cable trays are fabricated from continuous roll-formed AISI Type 304 and 316 stainless steel. They arenon-magnetic and belong to the group called austenitic stainless steels. Like carbon steel, they exhibit increasedstrength when cold worked by roll-forming or bending. Several important factors make the use of stainless steel imperative.Considerations such as: long term maintenance costs, corrosion resistance, appearance and locations where productcontamination is undesirable, are key factors in determining the necessity of Stainless Steel Material. Stainless Steelexhibits stable structural properties such as yield strength and high creep strength at elevated temperatures.NIEDAX Stainless Steel cable trays are welded using stainless steel welding wire to ensure that each weld exhibits thesame corrosion resistant characteristic as the base metal.

A detailed study of the corrosive environment is recommended when considering a stainless steel design.

RECOMMENDED USE

Electrogalvanized Zinc ASTM B633 Indoor (For Cable Tray Hardware and Accessories and Pre-Galv.)

Pre-Galvanized Zinc ASTM A653SS Gr.33 G90 (CSA Type 2) Indoor (Steel Cable Tray and Fittings)

Hot Dip Galvanized Zinc ASTM A123 (CSA Type 1) Indoor/OutdoorAfter Fabrication (Steel Cable Tray and Fittings)

Zinc CoatingsZinc protects steel in two ways. First, it acts as a protective coating and secondly, as a sacrificial anode to repair bareareas such as cut edges, scratches, and gouges. The corrosion protection of zinc is directly related to its thicknessand the environment. i.e, a .2 mil coating will last twice as long as a .1 mil coating in the same environment. Galvanizingalso protects cut and drilled edges.

Electrogalvanized ZincElectrogalvanized Zinc (also known as zinc plated or electroplated) is the process by which a coating of zinc isdeposited on the steel by electrolysis from a bath of zinc salts. This finish is standard for cable tray hardware and someaccessories for pre-galvanized systems. When exposed to air and moisture, zinc forms a tough, adherent, protectivefilm consisting of a mixture of zinc oxides, hydroxides, and carbonates. This film is in itself a barrier coating whichslows subsequent corrosive attack on the zinc. This coating is usually only recommended for indoor use in relatively dryareas, as it provides limited protection (ninety-six hours of protection in salt spray testing per ASTM B117).

US 12


Pre-Galvanized Zinc(Mill galvanized, hot dip mill galvanized or continuous hot dip galvanized)Pre-Galvanized steel is produced by coating coils of sheet steel with zinc. This process is accomplished by continuouslyrolling the material through molten zinc at the mills. This procedure is also used to produce mill galvanized and hot dipmill galvanized material. The coils are then slit to size and fabricated by roll forming, shearing, punching, or forming toproduce NIEDAX pre-galvanized cable tray products. The G90 specification calls for a coating of .90 ounces of zinc persquare foot of steel. This results in a coating of .45 ounces per square foot on each side of the sheet. This is importantwhen comparing this finish to hot dip galvanized after fabrication. During fabrication, cut edges and welded areas are notnormally zinc coated; however, the zinc located near the uncoated metal becomes a sacrificial anode to protect thebare areas within a short period of time.

Hot Dip Galvanized After Fabrication(Hot dip galvanized or batch hot dip galvanized)Hot Dip Galvanized After Fabrication cable tray products are fabricated from steel and then completely immersed in abath of molten zinc. A metallic bond occurs resulting in a zinc coating that completely coats every surface, includingedges and welds.A key advantage of this method is coating thickness. Cable trays that are hot dip galvanized after fabrication have aminimum thickness of 1.50 ounces per square foot on each side, or a total of 3.0 ounces per square foot of steel,according to ASTM A123.The zinc thickness can be controlled by the amount of time each part is immersed in the molten zinc bath as well as thespeed at which it is removed.The layer of zinc which bonds to the steel provides a dual protection against corrosion. It protects first as an overallbarrier coating. If this coating happens to be scratched or gouged, zincs secondary defense, galvanic action is calledupon to protect the steel.Hot dip galvanized after fabrication is recommended for prolonged outdoor exposure and will protect steel for manyyears in most outdoor environments as well as in many aggressive industrial environments.

US 13


CorrosionAll metal surfaces are affected by corrosion. Depending on the physical properties of the metal and the environment towhich it is exposed, chemical or electromechanical corrosion may occur.

Atmospheric CorrosionAtmospheric corrosion occurs when metal is exposed to airborne liquids, solids or gases. Some causes of atmosphericcorrosion are moisture, salt, dirt and sulphuric acid. This form of corrosion is typically worse outdoors, especially nearmarine environments.

Chemical CorrosionChemical corrosion takes place when metal comes in direct contact with a corrosive solution. Some factors whichaffect the severity of chemical corrosion include: chemical concentration level, duration of contact, frequency of washing,and operating temperature.

Storage CorrosionWet storage stain (White rust) is caused by the entrapment of moisture between the surfaces of closely packed andpoorly ventilated materials for an extended period of time . Wet storage stain is usually superficial, having no affect onthe properties of the metal.Light staining normally disappears with weathering. Medium to heavy buildup should be removed, in order to allow theformation of the normal protective film.Proper handling and storage will help to assure stain-free material. If product arrives wet, it should be unpacked anddried before storage. Dry material should be stored in a well ventilated low moisture environment to avoid condensation.Outdoor storage is undesirable, and should be avoided whenever possible.

Galvanic CorrosionGalvanic corrosion occurs when two or more dissimilar metals are in contact while in the presence of an electrolyte (ie.moisture). An electrolytic cell is created and the metals form an anode or a cathode depending on their relative positionon the Galvanic Series Table. The anodic material will be the one to corrode. Whether a material is anodic depends onthe relative position of the other material. For example: If zinc and steel are in contact, the zinc acts as the anode andwill corrode; the steel acts as the cathode, and will be protected. If steel and copper are in contact, the steel is now theanode and will corrode.

The rate at which galvanic corrosion occurs depends on several factors:

1. The amount and concentration of electrolyte present- Material stored in an indoor, dry environment will have little orno galvanic corrosion compared to a wet atmosphere.

2. The relative size of the materials- A small amount of anodic material in contact with a large cathodic material willresult in greater corrosion. Likewise, a large anode in contact with a small cathode will decrease the rate of corrosiveattack.

US 14


3. The relative position on the Galvanic Series Table. The farther apart in the Galvanic Series Table, the greater thepotential for corrosion of the anodic material.

StrengthEnvironmental Loads

Wind Loads

Wind loads need to be determined for all outdoor cable tray installations. Most outdoor solutions are ladder type trays,therefore the most severe loading to be considered is impact pressure normal to the cable tray side rails. The impactpressure corresponding to several wind velocities are given below in Table 1.

Table 1 Impact Pressures

V(mph) P(lbs/ft2 ) V(mph) P(lbs/ft2 )15 0.58 85 18.520 1.02 90 20.725 1.60 95 23.130 2.30 100 25.635 3.13 105 28.240 4.09 110 30.945 5.18 115 33.850 6.39 120 36.855 7.73 125 40.060 9.21 130 43.365 10.80 135 46.670 12.50 140 50.175 14.40 145 53.880 16.40 150 57.6

V= Wind VelocityP= Impact Pressure

Note: These values are for an air density of 0.07651lbs/ft3 corresponding to a temperature of 16C (60 F) and baro-metric pressure of 14.7 lbs/in2.

Example Calculation:

Side load for 6" side rail with 100 mph wind

(25.6 x 6)/12 = 12.8 lbs/ftWhen covers are installed on outdoor cable trays, another factor to be considered is the aerodynamic effect which canproduce a lift strong enough to separate a cover from a tray. Wind moving across a covered tray creates a positivepressure inside the tray and a negative pressure above the cover. This pressure difference can remove the cover from thetray.

US 17


Ice Loads

Glaze ice is the most commonly seen form of ice build-up. It is the result of rain or drizzle freezing on impact with anexposed object. Generally, only the top surface (or the cover) and the wind bearing side of a cable tray system issignificantly coated with ice. The maximum design load to be added due to ice should be calculated as follows:

LI = (W x TI x DI) / 144 where;LI = Ice Load (lbs/linear foot)W = Cable Tray Width (inches)TI = Maximum Ice Thickness (inches)DI = Ice Density = 57 lbs/ft3

the maximum ice thickness will vary depending on location. A thickness of 1 /2" can be used as a conservativestandard.

Example Calculation:Ice Loads for 24" wide tray with 1 /2" thick ice;

(24 x 0.5 x 57) / 144 = 4.75 lbs/ft

Snow LoadsSnow is measured by density and thickness. The density of snow varies almost as much as its thickness. Theadditional design load from snowfall should be determined using the building codes which apply for each installation.

Concentrated LoadsA concentrated static load represents a static weight applied at a single point between the side rails. Tap boxes,conduit attachments and long cable drops are just some of the many types of concentrated loads. When specified,these concentrated static loads may be converted to an equivalent, uniform load (We) by using the following formula:

We= 2 x (concentrated Static Load) / span lengthHowever, it should be noted that per NEMA Standard Publication VE1 cable tray is designed as a support for power orcontrol cables, or both, and is not intended or designed to be a walk-way for personnel.

Warning! Not to be used as a walkway, ladder or support for personnel.To be used only as a mechanical support for cables and raceway.

Support SpanThe strength of a cable tray system is largely determined by the strength of its side rails. The strength of a cable trayside rail is proportionate to the distance between the supports on which it is installed, commonly referred to as thesupport span. Therefore, the strength of a cable tray system can be altered by changing the support span. However,there is a limit to how much that strength can be increased by reducing the support span. At a certain point the strengthof the bottom portion of the cable tray could become the determining factor of strength.

Once the load requirement of a cable tray system has been established, the following factorsshould be considered:

US 18


1. Sometimes the location of existing structural beams will dictate the cable tray support span. This is typical withoutdoor installations where adding intermediate supports could be financially prohibitive. For this situation the appropriatecable tray must be selected to accommodate the existing span.

2. When cable tray supports are randomly located, the added cost of a higher strength cable tray system should becompared to the cost of additional supports. Typically, adding supports is more costly than installing a stronger seriesof cable tray. Future cable additions or the capability of supporting equipment, raceways for example, also favor strongercable tray systems.In summary, upgrading to a stronger cable tray series is typically more cost-effective than using the recommendedadditional supports for a lighter duty cable tray series.

3. The support span lengths should be equal to or less than unspliced straight section lengths, to ensure that no morethan one splice is placed between supports.

Deflection

Deflection in a cable tray system is primarily an aesthetic consideration. When a cable tray system is installed in aprominent location, a maximum simple beam deflection of 1/200 of support span can be used as a guideline to minimizevisual deflection.It is important at this point to mention that there are two typical beam configurations, simple beam and continuousbeam, and to clarify the difference.A good example of a simple beam is a single straight section of cable tray supported, but not fastened at either end.When the tray is loaded the cable tray is allowed to flex. Simple beam analysis is used almost universally for beamcomparisons even though it is hardly practical in the field. The three most prominent reasons for using a simple beamanalysis are: calculations are simplified; it represents the worst case loading; and testing is simple and reliable.Continuous beam is the beam configuration most commonly used in cable tray installations. An example of thisconfiguration is where cable trays are installed across several supports to form a number of spans. The continuousbeam possesses traits of both the simple and fixed beams. When equal loads are applied to all spans simultaneously,the counter-balancing effect of the loads on both sides of a support restricts the movement of the cable tray at thesupport. The effect is similar to that of a fixed beam. The end spans behave substantially like simple beams. Whencable trays of identical design are compared, the continuous beam installation will typically have approximately half thedeflection of a simple beam of the same span. The published load data in the NIEDAX cable tray catalog is based on thecontinuous beam analysis per IEC - Standard 61537. Therefore simple beam data should be used only for generalcomparison purposes.

The following factors should be considered when addressing cable tray deflection:

1. Cost evaluations must be considered when addressing cable deflection criteria.2. Deflection in a cable tray system can be reduced by decreasing the support span, or by using a taller(side rail height)or stronger cable tray.3. The location of splices in a continuous span will affect the deflection of the cable tray system. The splices should belocated at points of minimum stress whenever practical.

NEMA Standards VE-1 limits the use of splice plates as follows:

Unspliced straight sections should be used on all simple spans and on end spans of continuous span runs.Straight section lengths should be equal to or greater than the span length to ensure not more than onesplice between supports.

US 19


Barrier RequirementsBarrier strips are used to separate cable systems, such as when cables above and below 600 volts per NEC 318-6(f) areinstalled in the same cable tray. However, when MC type cables rated for over 600 volts are installed in the same cabletray with cables rated 600 volts or less, no barriers are required. The barriers should be made of the same material typeas the cable tray. When ordering the barrier, the height must match the loading depth of the cable tray into which it isbeing installed.

Future Expansion RequirementsOne of the many features of cable tray is the ease of adding cables to an existing system. Future expansion shouldalways be considered when selecting a cable tray, and allowance should be made for additional fill area and loadcapacity. A minimum of 50% expansion allowance is recommended.

Space LimitationsAny obstacles which could interfere with a cable tray installation should be considered when selecting a cable traywidth 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.

LengthLengths AvailableThe current Cable Tray Standard, NEMA VE-1 and C22.2 No. 126.1-98, lists typical lengths as 3000 mm (10 ft), 3660mm (12 ft), 6000 mm (20 ft), and 7320 mm (24 ft). It is impractical to manufacture either lighter systems in the longerlengths or heavier systems in the shorter lengths. For that reason, NIEDAX has introduced a primary and secondarylength for some systems. These straight section lengths were selected to direct the user to trays that best suit supportspan demands and practical loading requirements. The primary length is the one that is the most appropriate for thestrength of the system and that will provide the fastest service levels. The secondary lengths will be made available toservice additional requirements. Special lengths are available upon request with extended lead times.

Support SpanThe support span on which a cable tray is installed should not exceed the length of the unspliced straight section. Thusinstallations with support spans greater than 12 feet should use 240" (20 feet) or 288" (24 feet) cable tray lengths.

Space LimitationsConsideration should be given to the space available for moving the cable tray from the delivery truck to its finalinstallation location. Obviously, a shorter cable tray will allow for more maneuverability in tight spaces.

Installation

Shorter cable tray lengths are typically easier to maneuver on the job site during installation. Multiple people may beneeded to manipulate longer cable tray sections, while shorter sections can generally be handled by one person.Although longer cable tray lengths are more difficult to maneuver, they can reduce installation time due to the fact thatthere are fewer splice connections. These considerations should be evaluated for each job / install.

US 20


Loading PossibilitiesPower Application:Power applications can create the heaviest loading. The heaviest cable combination found was for large diametercables (i.e. steel armor, 600V, 4 conductor 750 kcmil). The cables weigh less than 3.8 lbs. per inch-width of cabletray. As power cables are installed in a single layer, the width of the cable affects the possible loading.

Data/Communication Cabling:Low voltage cables can be stacked as there are no heat generation problems. The NEC employs a calculation of thetotal cross sectional area of the cables not exceeding 50% of the fill area of the cable tray. As the cable fill area of thecable tray system affects the possible loading, both the loading depth and width of the systems must be considered.For this example 4UTP category 5 cable (O.D. = .21, .026 lbs./ft.) were used.

Other Factors To ConsiderSupport Span - The distance between the supports affects the loading capabilities exponentially. To calculateloading values not listed use:

W1 x L12 = W2 x L22

W1 = tested loadingL1 = span in feet, a tested spanW2 = loading in questionL2 = known span for new loading

Other Loads - Ice, wind, snow for outdoor systems see page 16 and 17 for information.

A 200 lb. concentrated load for industrial systems. The affect of a concentrated load can be calculated as follows

2 x (concentrated static load) / span in feetWhen considering concentrated loads the rung strength should be factored in.

Length Of The Straight Sections:The VE-2, Cable Tray Installation Guide, states that the support span shall not be greater than the straight sectionlength. If a 20C system is manufactured in 12 foot sections the greatest span for supports would be 12 feet. Thisdramatically affects the loading of the system.

W1 x L12 = W2 x L22100 x 202 = W2 x 12240,000 = 144 x W2

W2 = 277 lbs. per foot

Type of CableAccording to NEC Article 318, multiconductor tray cable may be installed in any standard cable tray bottom type.Single conductor tray cable may be installed only in ladder or ventilated bottom cable trays (not solid bottom). Solidbottom cable trays are not allowed to be installed in Class II, Division 2 locations (1999 NEC Section 502-4(b) ). Ingeneral, small, highly flexible cables should be installed in solid bottom, vented bottom cable trays. Sensitive cables(e.g. fiberoptic) are typically installed in flat, solid bottom cable trays, instead of corrugated trough bottoms. Larger, lessflexible cables are typically installed in ladder type cable trays having 12" rung spacing.

US 21


Cost vs. StrengthOn most installations more than one bottom type is acceptable. Economic factors should be considered at this point.Ladder cable trays have a lower cost than either solid or ventilated bottom configurations. Typically, the cost of laddertype cable tray decreases as rung spacing increases. Rung spacing can affect individual rung and side rail loading aswell as system load capacity.

Cable ExposureTray cables are manufactured to withstand the environment without additional protection, this favors the use of a laddertype cable tray. Some areas may benefit from the limited exposure of solid or vented bottom cable tray. Solid Bottommetal cable tray with solid metal covers can be utilized in other spaces used for environmental air to support nonplenum rated tray cables (1999 NEC 300-22(C)(1) )

Cable AttachmentThe major advantage of ladder type cable tray is the freedom of entry and exit of the cables. Another advantage of laddertype cable tray is the ability to secure cables in the cable tray. With standard rungs the cables may be attached witheither cable ties or cable clamps. The ladder type cable tray is also available with special purpose, slotted marine orstrut rungs to facilitate banding or clamping cables. Cable attachment is particularly important on vertical runs or whenthe tray is installed on its side. Ladder rung spacing should be chosen to provide adequate cable attachment pointswhile allowing the cables to exit the system.

Fitting RadiusCable FlexibilityThe proper bend radius for cable tray fittings is usually determined by the bend radius and stiffness of the tray cables tobe installed. Typically, the tray cable manufacturer will recommend a minimum bend allowance for each cable. Thefitting radius should be equal to or larger than the minimum bend radius of the largest cable which may ever be installed.When several cables are to be placed in the same cable tray, a larger bend radius may be desirable to ease cableinstallation.

Space LimitationsThe overall dimensions for a cable tray fitting will increase as the bend radius increases. Size and cost make thesmallest acceptable fitting radius most desirable. When large radius fittings are required, the system layout must bedesigned to allow for adequate space.

FITTINGS INSTALLATIONRecommended Support Locations for FittingsThe following are recommended support diagrams to serve as guidelines for installing Steel Cable Tray support systemsin the field. The information is intended to provide the installer some practical assistance when estimating the amountsof necessary supports and to help in identifying support locations for various field conditions. However, it does not coverevery situation that may arise when installing the product. It may be possible to install narrow trays with lighter loadsand fewer supports. Wider trays with heavier loading, trays with long radii, or those with multiple side cuts may requireadditional support to avoid unwanted deflection.

US 22


Horizontal Elbow SupportSupports for horizontal cable tray fittings should be placed within 2 ft. (600 mm) of each fitting extremity, and as follows:

a. 90 supports at the 45 point of arc.b. 60 supports at the 30 point of arc.c. 45 supports at the 22-1/2 point of arc

(except for the 12 in. [300 mm] radii).d. 30 supports at the 15 point of arc
