UL Pullout Test Requirement 35lbs for 1 minute Tray Cable 1. Not generally perfectly circular 2. Considerred a raceway (longer lengths possible) 3. Fittings are approved for various portable cords AND Tray Cables 4. UL Pullout Test Requirement 50lbs for 3 minutes

4 Uses Not Permitted: Other Test Differences Portable CORD UL514B Tray Cable UL514B Samples: 2 each trade size (I each on min and max cord sizes) Samples: 3 each trade size on min cable size; 3 each trade size on ax. cable size for each required sequence. Types (Test Sequences): Strain relief only (dry location) Liquidtight (includes UV and oil spray resistance) Types (Test Sequences): Based on declaration of for use with types of TC cable Dry location Only Sunlight Resistance (Resistance to rain, UV resistance and effect on pullout performance) Sunlight and Oil Resistance (Resistance to rain, UV, and oil immersion and oil spray) Unique Test Parameters: Effects of flexing before Pull Pull force and time: 35 lbs./ 1 minute Unique Test Parameters: Pull force and time: 50 lbs./ 5 minutes Oil immersion for Oil resistance rating Oil Res. I and Oil Res. II classifications based on temp. rating (60ºC or 75ºC) of the intended cable. NEC Flexible Cord Article 400 NEC Tray Cable Article 336 Flexible cord is not considered a substitute for the fixed wiring system of a structure (NEC Section 400.8(1). The Uses Permitted (400.7) and Uses Not Permitted (400.8) are specific and generally imply uses where flexibility and quick connect/disconnect interchangeability at equipment is required. More particular uses for flexible cord are found throughout the code but none deviate from these principles. Tray cable is considered as a fixed wiring system and is not restricted in installed length. Uses Permitted: In cable tray, raceways and outdoors supported by messenger wire. Class I remote control, signaling and power limited circuits (NEC Art 725, I and II. Non-power limited fire alarm circuits in accordance with NEC Section Type TC-ER in specific industrial applications according to (7). In wet locations (marked for use) In direct sunlight (marked for use) Direct buried in earth (marked for use)

5 White Paper A wide disparity seems to exists between the estimated annual shipments of Power and Control Tray Cable-Type TC and the demand for listed Tray Cable fittings. NEC Section states that Fittings and connectors shall be used only with the specific wiring methods for which they are designed and listed. One assertion that can be made to explain the wide disparity between the use of Type TC cable and the demand for appropriately listed fittings, is that inappropriate fittings are being installed with this cable. UL 514B, Conduit, Tubing and Cable Fittings, contains the listing requirements for fittings intended for use with Tray Cable-Type TC. These requirements reflect the applications for Tray Cable in accordance with the NEC Article 336 as a general, fixed wiring system. According to UL 514B, listed Tray Cable fittings are required to be marked For Tray Cable, on the fitting or its smallest unit shipping package. This marking, in conjunction with the mark of the nationally recognized testing laboratory, is proof of compliance with the NEC requirement. Closest in design to a typical fitting listed for Tray Cable are fittings listed for use with Flexible Cord. Despite their outward similarity, the performance requirements in UL 514B for Flexible Cord fittings are far less stringent than for Tray Cable fittings. The significant difference in test requirements reflects the use of Power and Control Cable Tray as a more general, fixed wiring system as opposed to the restricted uses for Flexible Cord in NEC Article 400. Flexible cord is not considered a substitute for the fixed wiring system of a structure. The seemingly widespread assumption that flexible cord fittings, or listed fittings for other cable types are suitable for use with Tray Cable is a serious mistake and a potential compromise to safety. UL514B also requires marking for use with Oil Resistance I or II and or Sunlight Resistant cables. The CSA testing makes no reference but clearly the Silver Grip is sunlight resistant. This can all be picked up during a UL test program.

6 Differences between Tray Cable and Cord:

7 MC CABLE - Metal clad cable, factory assembled with 2 or more conductors, enclosed in a metallic corrugated tube or interlocking armor.

8 TECK CABLE - Similar to MC cable, with additional PVC jacket surrounding cable conductors inside the armor cable.

9 Will Metal Clad Cable Replace Rigid Conduit? NEGATIVES: Very Expensive Not as durable as Rigid Does not have the installed base (acceptance) rigid has POSITIVES: No conduit bodies required Lighter, more flexible, than Rigid Eliminates EYS seals and related nipples Cable already pulled Installations are a cake walk compared to rigid (re-work)

Acts as plunger, allows for double potting when using putty Serrated hub bites into painted enclosure for optimum bonding, Built in sealing device seals even against rough surface or slight offset install

16 1. Prepare Cable 2. Install STEX on Cable 3. Tighten Gland Nut

17 4. Remove Armor Stop 5. Pot cable using liquid or putty* 6. Put Hub on enclosure 7. Tighten Gland Nut

18 TERMINATOR - TMC, TMCX No locking cone Spring design has no bite! Armor contact Located near entrance, strip length more critical Large body, (compare to T&B s compact size) Cannot tighten with screwdriver

22 GM127 STAR TECK STE & STEX Literature Cheat Sheet AVAILABLE!

23 1. Prepare Cable Required length inside enclosure determines starting point Cut away small section of PVC Remove Armor using hack saw or tube cutter Measure strip length of PVC Jacket using Gland Nut

24 2. Install STEX on Cable Using Hub opening end, determine if wires will pass through with armor stop installed, if not unthread stop Insert wires through fitting, push armor till bottoms out, pull back

25 3. Tighten Gland Nut Either using two channel locks or by installing hub side in enclosure Completed when bushing extrudes ( rounds-out ) around jacketed cable

26 4. Remove Armor Stop Unscrew armor stop Separate hub from body by unscrewing red union Separate wires apart for potting

27 5. POT CABLE Using Liquid: Using Putty: A. Use Fiber to dam around and between all conductors B. Stabilize fitting in Vertical condition C.Mix compound until even, clip corner and pour slowly A. Mix putty into even blue color B. With cone off, dam between conductors, forming a cone C.Replace metal cone, dam around conductors again

28 6. Put Hub on enclosure 7. Tighten Gland Nut
