The NEC. also has permitted cable tray for use as an equip ‘ment ground conductor since 1975. Cable tray systems can provide significant advantages in cable fill over other wiring methods. This can provide savings in the size or number of raceways required thereby reducing both material and labor costs. Jn many cases the N-E.C. permits greater conductor am- ppacities in cable tray than for other wiring methods. Un- der certain conditions, the N.E.C. allows “Free Air” rating fof large, single conductor power cable (250 MCM & larger) in ventilated cable tray systems. This can provide o CABLE TRAY GENERAL significant savings in conductor costs, Cable tray permits much greater spacing between support hangers than for most other systems, providing sevings in support costs and installation labor. Square D cable trays, are available for support spacings ranging from 8 to 20 foot support spans. ‘Square D ladder, trough, solid bottom, and channel type ‘ray is available in steel and aluminum, and in varying width and load depths for many applications including primary service entrance, main power feeders, branch wir- ing, instrument and communications cable. Square D cable tray is built in general accordance with National Electrical Manufacturers’ Association (NEMA) Standards Publication VE-I (current issue 1979). VARIOUS TYPES OF CABLE TRAY Ladder-type cable tray consists of two longitudinal side rails connected by individual cross members or rungs. Square D ladder designs are very popular due to their versatility and lower costs, They also provide: maximum ventilation for conductor cooling, smooth edges on side rails and rungs to protect cables, and slots (double rung design) for easy cable fastening when required. ‘Various rung spacings aré available (6, 9, 12 and 18 inches) to provide support for most cables, from small flexible cables to the most rigid interlocked armor power cable, Nine inch rung spacing is the most popular since it provides support for the widest range of cable sizes. rough-type cable tray consists of two side rails with closely spaced rungs or ventilated bottoms. It provides ‘maximum cable support while maintaining adequate open- inx’"” petmit air circulation for cable cooling. Trough é “¢ most often used (in liew of ladder trays), to pro- \yaze-wuditional support and protection for smaller signal, communication, and instrumentation cables. ‘Square D trough designs also provide smooth surfaces and ‘adequate openings for cable dropouts, without the need for ‘cutting of trough bottom materials Solid bottom cable tray consists of two side rails connected ‘with a corrugated or reinforced solid bottom. Solid bottom trays are most often used to provide electrical or magnetic shielding for very sensitive communications and signal ci ‘cuitry. Solid bottom trays also provide maximum protec tion of cables, but require a reduction in cable fill from ladder or ventilated trough trays. CChannel-type tray is of one piece construction and is avail able in 456 and 6 inch widths. It is most often used in place of conduit to carry one or two cables from a main _eable tray run to individual equipment or termination points, Square D channel is offered in ventilated and solid desions. 2 © Saune 0 Compa SQUARE T) COMPANY vee retMAY, 1985 ‘The National Electric Code® places very few restrictions ‘on the use of cable tray. As a result, cable tray is often the best, most economical choice over other wiring methods for a wide variety of applications. ‘The following wiring methods are permitted to be installed in cable tray systems: 1, Mineral-insulated metal-sheathed cable (MI) — Art 330. 2.

Olney MaCABLE TRAY ENGINEERING INFORMATION MAY, 1985 BASIC DEFINITIONS Side Rails or side members (sometimes referred to as stringers) are the basic structural components of the cable tray system. The side rails provide structural support and protection to the cables to be installed. Square D side rails are an efficient channel-shape with rounded flanges to protect cables. Side rail flanges are tured inward, mini- mizing the overall size of the cable tray enclosure, Rungs are the transverse members which are rigidly welded to the side rails to form a rugged cable tray as- sembly. The double rung provides smooth edges to permit ‘cable dropout without sharp edges to damage cable and provides slots for easy cable fastening, An optional box rrung design is also available if desired Rung Spacing is generally the centerline distance be- ty" rungs in ladder-type trays, measured along the di- x of the side rail. On horizontal elbows, the rung spisy is generally maintained at the centerline of the fitting, Note that the rung spacing of Square D's double rung is the distance between the centerline of cable bear- ‘surfaces measured between adjacent double rungs. Length — Square D straight section tray is available in MATERIALS Aluminum — The prime alloy used in the structural mem- bers of Square D aluminum cable tray is a special, high strength 6063-T6 alloy (special yield strength of 30,000 psi). The 6000 Series alloys contain minor proportions of ‘other elements which allow for heat treatment while main- taining excellent strength characteristics. The 6063-T6 alloy. -o has excellent forming and welding properties. (tite metal in many applications, aluminum pos sesses the desirable combination of low weight and high strength. These advantages, combined with good corrosion resistance and relatively high electrical conductivity, make aluminum an excellent choice for use in cable trays. Mill-Galvanized Steel — Mill-galvanized, pre-galvanized, and even “hot dip galvanized” are terms given to steel that is galvanized at the steel mill, The mill-galvanized process involves passing sheet or coil steel through molten Zine baths, at relatively high rates of speed. The final product ig a steel with a relatively smooth protective zine coating. During cable tray fabrication where slitting, forming, cut- ting, or welding is performed, the cut edges and heat- affected zone of welding are subject to superficial oxida- Saunas couenn ol 12 foot lengths. 24 foot lengths are also a heavy duty, long span designs. ble for th — Square D cable tray is available in 6, 12, 18, 24, 30, and 36 inch widths. Fill Depth, loading depth, or inside depth are all terms used to define the depth available for cable fil. The load- ing depth is measured from the top of the cable bearing surface of the rung or bottom, to the top of the side rai Overall Height is generally the total height of the side rail. It is sometimes referred to as nominal tray height and is often used in Tiew of fill depth to specify cable tray side rail requirements. Fittings & Radius ~ Cable tray fittings such as horizontal elbows, vertical outside bends, vertical inside bends, tees, and crosses, are available to facilitate changes in direction in cable tray systems. Fitting bending radii of 12, 24, and 36 inches are available. Fitting radius is generally deter- ‘mined by the minimum allowable bending radius of cables to be installed. Refer to the National Electric Code and cable manufacturer for minimum cable bending radius. AND FINISHES tion. These areas are protected by the zinc coating on the adjacent surfaces which corrodes sacrifically by an elec- tro-chemical process. Mill-galvanized steel used in Square D's cable tray is coat cd in conformance with ASTM Specification A-525 G-90, ‘The G-90 coating provides 1.25 ozs. of zine per square foot of steel (both sides of the sheet). This converts to an average coating thickness of 1.06 mils per Hot dip galvanized after fabrication (HDGAF) refers to a galvanizing process that is performed on finished assem- blies after all forming, cutting, and welding operations have been completed. ‘The bare steel assembly is thoroughly cleaned and totally ymersedi in a bath of molten zinc. The result is a cable tray that is totally coated and protected with a zine alloy ‘bond. Some degree of roughness and variation in thickness can be expected due to the hot dip galvanized process. Square D cable trays are hot dip galvanized in abcord: ance wth ASTM Specification A-S86 Class B2 which pro- Wides an average zine coating weight of 130 or. per sQvare Toot etch sie o hee.

The following infor- ‘mation is presented to aid the designer/user in the best application of our products to suit his particular require- _ ments, Cable Tray Loads — Cable tray loads are generally uni- form loads expressed in pounds per linear foot. Loads ‘commonly referred to in the cable tray industry are: # Cable Load —Total static weight of the cables to be supported in the tray. This may include future cable loads if applicable. ‘¢ Live Loads — Weather loads, such as wind, snow, and ice, should be considered in outdoor installations. Con- sult local building codes to determine appropriate en- vironmental loads to apply to your cable tray system. ‘© Working Load— Combination of the cable load and live loads to be applied to your cable tray system. ‘* Allowable Load — Load carrying capacity of the cable tray system. It is the destruction load capacity of the cable tray divided a safety factor of 1.5. The allowable Toad capacity should equal or exceed the working load to be applied. Cig sure corny ‘Support Spans — A support span is merely the centerline to centerline distance between supports. In actual practice, ‘the support spans of an installed cable tray system will vary, but the engineer/user should specify the maximum support span, Two support spans commonly referred to ‘© Simple Beam—A single span with the ends free to rotate, This type span rarely occurs in normal installa- tions, but is used as the most severe case when testing cable tray to determine load capacity. © Continuous Beam—A series of spans connected to- gether and continuous over several supports. This type span more closely approximates an actual installation. Determine the most economical support spacing by re\ ing building structure and any existing support structures. In many cases, it can be less expensive to support a stronger tray system over longer spans by reducing the number of supports. Cable tray fittings should be supported in accordance with NEMA Standard VE 1, Part 6. In addition, supports should be located on each side, and in close proximity to, expansion splices and vertical and horizontal hinged splices, (Structural Information continued on next page.)al CABLE TRAY. ENGINEERING INFORMATION MAY, 1985 STRUCTURAL INFORMATION (continued from previous page) Support Types —The most common types of cable tray supports are: © direct rod suspension with all-thread hanger rod, sup- porting the tray via cable tray hanger cli ‘© trapeze hangers consisting of a support angle or chan- inel suspended by allthread hanger rods; © wall brackets anchored to walls or columns. NEMA Load Classes —NEMA Standard VE 1, Part 3 outlines load/span class designations to be utilized by the designer/user to specify a tray system to meet his struc- tural needs. The designation is of the form 8A, 12A, 20C, ‘ete, The numerical part refers to the support span, in feet. ‘The alpha character in the designation refers to 2 load catevesy, Current NEMA load/span designations are as aC won Rare Load capacities for trays are determined by test standards outlined in NEMA VE 1, Part 4. Each tray is supported fon a simple beam span and is loaded uniformly to destruc- tion. The total destruction load divided by a safety factor of 1.5 represents the working load of the tray. Since eable tray is rarely supported on simple beam spans, the ar~val installed safety factor of multiple spans is 20 to reent higher (see beam diagrams for comparative ul ments). Deflection — Deflection is the vertical displacement from its original position of a cable tray when loaded. In gen- eral, the maximum deflection occurs at midspan or mid- ‘way between supports Deflection requirements normally imposed on structures by building codes are primarily a consideration to avoid damage to finish materials applied to them. The only ‘major concerns for deflection limits on cable tray should bbe from an aesthetic standpoint and to avoid interference with adjacent items. Deflections shown on the selector chart and data sheets of this catalog are for simple beam spans. Deflections for multiple installations are % to ¥ of those shown (see beam diagrams). SQUARE [D) COMPANY DI Beam Diagrams M= Bending Moment A = Deflection Values shown for bending moments and deflections are expressed as fractions of simple beam span values (assum- {ng equal uniform loads and span lengths). Five span jon Properties — Certain structural properties for each side rail section are shown on the data sheets in this cata- log. The following is a short explanation of each of these properties: ‘Ske = Compressive section modulus taken about the ma- jor axis— a measurement of the section’s strength of resistance to bending.* Ix = Moment of inertia taken about the major axis—a measurement of the section's resistance to deflec- tion.* Tye = Moment of inertia of the compressive section of the side rail taken about the minor axis — a meas urement of the section’s resistance to lateral buck= ‘A= Minimum area of the two side rails combined, “These properties are expressed for one side rail only. Double the values shown in the data sheets to evaluate fan assembled tray. O)e MAY, 1985 CABLE TRAY ENGINEERING INFORMATION SQUARE D STRUCTURAL FEATURES All Square D side rail sections are designed for maximum. strength at economical costs. The top flange of each straight section is designed to resist lateral and local buck- Ting of the cable tray, which are the most common modes of failure in cable tray. All Square D cable trays feature rugged welded con- struction, All tray designs utilize high strength splice joints which allow for random location between supports in installations ‘consisting of two spans or more, Splices in a simple beam ‘span and more than one splice in a span should be avoided, Splices are provided with splined shoulder bolts which bite into the side rail and splice to insure a tight fit. Heavy duty tray designs include angle splices which use bolts through the flange to provide additional strength. ‘THERMAL CONTRACTION AND EXPANSION Consideration should always be given to the thermal con- traction and expansion of cable tray systems. It is particu- larly important when relatively long straight rons of cable trays are installed and when large temperature differences ‘are possible such as in outdoor installations and in certa industrial processes. ‘Table 6-1 of NEMA VE-I provides straight run lengths at various temperature differentials and materials which re- sult in a 1 inch expansion or contraction. This information should be used to determine if it is necessary to make provisions for expansion and contraction in straight cable | 1 required, provisions for expansion jn. straight runs Should be mage through the use of expansion guides and txpansion splice plats. These permit the tay to expand nd. contrac, relative to the support, with changes in temperature, The cable tray should be secured or fixed wih standard hold down clips at one suppor point mid- vray between expansion. splice plates. Expansion guides Should be used at all other support locations between ex- pansion splice plates Square D expansion splice plates allow for 1 inch of move- ron, Distance between expansion splie plates should be Geterined using the table above. For proper operation of the expansion splice, the appro- Prats gap seting a the time of installation is very impor tint. Reler to NEMA VE-I for proper gap setting proce- dures. Note, supports should be located on each side and fn lose proximity to the expansion splice joint SQUARE J) COMPANY. All of Square D's cable tray rungs and bottoms are capa- bbe of withstanding a 200 Ib. static concentrated load (ap- plied to the midéle sx inches) without permanent de- formation, It should be noted, however, since cable tray is designed 1s a support for cables and tubing, that it is not intended fo designed as a walkway for personnel. Square D aids the user/installer in expressing this caution by the following statement on each product label: “WARNING! Cable tray is not to be ‘used as a walkway, ladder, or support for personnel. To be used only as a mechan- ical support for cables and tubing,” 5 EQUIPMENT GROUND CONDUCTOR Article 318-6 of the National Electric Code permits the use of cable tray as an equipment ground conductor. Cable trays are classified by Underwriters Laboratory for this, use, The equipment ground conductor rating of cable tray is determined by the cross sectional area of the tray. This, generally amounts to the combined cross section area of both side rails. ‘The following NE.C. Table provides equipment ground ‘conductor ratings for cable tray. ‘A separate ground conductor must. be used to obtain ‘ground ratings larger than those listed in the above table. When cable tray is used as the equipment ground, care ‘must be taken to insure a continuous electrical path. Bond- ing jumpers must be used where discontinuities may exist jn the tray run such as, across expansion splice plates and hinged splice plates. Note, in all cases, cable tray must also be grounded as required for equipment enclosues in article 250 of the NEC.CABLE TRAY ENGINEERING INFORMATION yy ‘SwrTcHeOARD E epugnot exnren Re setae 28 el as aS lS =| S os SIF ex MAY, 1985 eXtwancese™ee ON.

This will not only aid the man- tufacturer, purchaser, and installer, but will certainly bene- fit the end user as well. We have provided below specifica- tion guidelines which should be considered when preparing a cable tray specification. Class Designation — The NEMA designations relate to both support spans and cable load. The designations for Square D trays are shown on each cable tray data sheet ‘and also on the selector chart on pages 10 and 11. The specifier should choose the most appropriate class as it relates to his particular load and support span require- ments. ‘Tray Type — The four basic types of cable tray are shown, con page 2 of this catalog. For a large number of applica tions, a ladder tray is normally adequate. For smaller or more flexible cables, a trough tray may be more desirable. If the tray is intended to carry sensitive signal and com- ‘munications wiring, the solid bottom tray may be more suitable. For extensions off the main tray run, channel tray for support of one or two cables should be utilized. Material — Square D Cable trays are available in ¢i aluminum or steel. The relative merits of each material given in the discussion on page 4 and the materials com- parison chart on page 5. Aluminum trays are generally constructed of alloy 6063-T6; and steel trays are of carbon steel per ASTM A-569, A-366, or A-526. Finish —If aluminum tray is selected for use, the tray will be supplied in a natural finish state. If steel tray is desired, the specifier must state the type of zine coating preferred, Trays of mill-galvanized steel (ASTM A525) are normally suitable for indoor applications. For more SQUARE F COMPANY. severe environments, the HDGAF finish (ASTM A386) should be specified. See the materials comparison chart on page 5 for additional information. Rung Spacing — If a ladder type tray has been selected, the specification must indicate the desired ladder rung spacing. NEMA Standard rung spacings are 6, 9. 12, and. 18 inches. Nine inch spacing is most commonly specified since it is the best compromise for most cable support situations. Data sheet pages 12-25 show details and spac- ing of the rungs used in Square D ladder type trays. Inside Depth— This item may be based on the outside diameter of the largest cable to be installed in the tray system, Also, in the case of multiple layers of cable (pa ticularly control and signal type), the inside depth governs the square inches available for cable fill in association with the tables CFI through CFS on pages 44 and 45 of this catalog. Square D Cable trays are available in usable depths of 3, 4, and 5% inches in accordance with NEMA. Standard VE-1. Radius — This refers to the bending radius of the cable tray elbows and fittings. NEMA Standard 12, 24, or 36 inch radius can be specified in order to limit the bending radii of the installed cables. Covers —If tray covers are required, the cover material should be the same as that of the tray to be covered — steel or aluminum. Square D Cable Tray Covers are avail- able in aluminum and mill galvanized steel (ASTM A-525, G90 coating class). Covers can be specified in solid or ventilated, flat or flanged. Flanged covers are most often specified but are more expensive than flat covers. If flanged covers are required the specifier should specifically indicate if flanges are required on fitting covers. cpCABLE TRAY DATA SHEET MAY, 1985 3” DEEP ALUMINUM ouags LADDER 124 Product Features: Z cxauetnay + Rugged welded construction. gon sr ‘© Space saving design (siderail flanges turned in). aan oeea { omen'nirrowe”” Serr eye ree Soa ng design permits easy cable dropout with no sharp ‘to damage insulation. ° -4 double rung permits simple cable fastening. + Rungs will support a 200# concentrated Joad (static concentrated load applied to middle six inches with zo permanent deformation).

Consult your cable manufacturer.or the National Elestric Code for recommended bending radii of the cables to be installed. For ordering purposes, use the basic tray prefix as shown fn the data sheet (Page 12-25) and insert it before the descriptive portion of the catalog number as shown on the CABLE TRAY MAY, 1985 FITTINGS following pages. Each fitting comes complete with the required number of appropriate splice plates and associ- ated hardware, (2 plates with each horizontal or vertical elbow, 4 plates with a tee, and 6 with a cross fitting). All Square D fittings are manufactured without tangents past the point of curvature, This feature allows for an ‘offset to be made in the least possible space and also pro- vides for simple field cutting to other degree fittings if required. The no-tangent aspect also permits the use of a common splice plate for both straight tray and fittings. (NOTE: The flange hardware of the angle splice plate is not required on fittings).

DyCR C May, 1985 ‘The following tables have been compiled to assist in deter maining the proper size tray to use and to aid the designer in utilizing the maximum ampacity rating of the con- ductors placed in the trays. Cable Fill Tables CFI through CFS are based on the Na- tional Electric Code Article 318-8, -9, and -11. They com= bine each table shown in the Code, with its appropriate ‘written information, into one common application chart. Included are separate charts for ladder, trough, solid bot- tom, and channel trays and also data based on the type of circuit function that the cables perform, both multicon- ductor and single conductor, at varying voltage classes. Ampacity Tables on pages 46 through 49 represent the ampacity ratings of selected conductors as they apply to their use in cable trays. The ratings shown herein are the maximum ampacities available for any multi-conductor y= eable in tray (as defined in the cable fill charts) even though the assembly may consist of more than three indi vidual conductors within the same outer covering. Note CABLE TRAY DATA TABLES or ECT that for applications of 2000 volte and less, the derating factors of note 8 in the Code (regarding more than three conductors in a raceway or cable) does not apply to cable trays. Deration Tables — Important; the ampacity of any cable installed in eable tray is governed by the factors expressed in Deration tables DR1 and DR2. These tables depict the combinations of cable voltage and covered or uncovered trays and state any deration factor to be applied based on specific installation criteria, Cable Data Tables CD1 through CDS are presented only as a very abbreviated list of the many different types of cables that may be installed in cable trays. The values shown are a composite of several major cable manufac- turers’ published data and should not be used for exact, design. The data is presented as a general guide only; users should consult Square D or the cable manufacturer for further information regarding exact dimensions and suit- ability for use in cable trays. or sonet warined | “ho. or cone — | oan muvee rae _|rsoe quent | mover wre pecs taooenaoven,souseor. | en | a casts rut | 20 orn we es oy trooen rover, sounsor, | ert | a caste ru, | 00 or tne we Pues cna a [a caste rut | 200 or le we owen vesteo TAY cn | cusuere | oma | wcawe | anruse ors | surncsty 2000 ole we ‘avo ane | a, are ‘00 ores we saomanca fe ree | ar avons mot-oeo | veeu era seat, nurse | at auncir pons | yea selena ine panes | as auonest zonvswoo | ween | MNEMED seonormare nurse | po | tence morose | MICAL mo nurs | Cy vata bra J puescire mor-sweo [wey ranoou are | a AMPACITY. 2001 - 38000 MIC AL SPACING “0 berarion pwernn | weave om | eration onrae | wease cel as nots oaTA 20 von wie-t6 oo | s crete Osta 00 vot we we ame lees cate DATA too ok ue cs | cvsie one | aeor-stom | mane cm | caste oara | sos 200 we coe | at Conductor Ca Tray Cable P= Power Cecult Use Lighting iret Use $$ Signal Cieuit Use Sear8 ota SQUARE J) COMPANYMAY, 1985 CABLE TRAY CABLE FILL CF1— POWER LIGHTING, CONTROL, SIGNAL CABLES ‘MULTICONGUCTOR CABLE FILL (2000 V.
