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 760.27. Type TC-ER in specific industrial applications according to 336.10(7). In wet locations (marked for use) In direct sunlight (marked for use) Direct buried in earth (marked for use)
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 300.15 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.
Differences between Tray Cable and Cord:
MC CABLE - Metal clad cable, factory assembled with 2 or more conductors, enclosed in a metallic corrugated tube or interlocking armor.
TECK CABLE - Similar to MC cable, with additional PVC jacket surrounding cable conductors inside the armor cable.
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)

UNIQUE FEATURES FOR STAR-TEK HAZARDOUS LOCATION STX, STEX ORDINARY LOCATION ST,STE Only locking cone in the industry. 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
1. Prepare Cable 2. Install STEX on Cable 3. Tighten Gland Nut
4. Remove Armor Stop 5. Pot cable using liquid or putty* 6. Put Hub on enclosure 7. Tighten Gland Nut
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
Appleton copies Crouse Hinds. Engineer leaves Crouse, goes to Appleton and knocks off the design Uses same TMC, TMCX Prefix approach FFB same as CH.

GM127 STAR TECK STE & STEX Literature Cheat Sheet AVAILABLE!
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
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
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
4. Remove Armor Stop Unscrew armor stop Separate hub from body by unscrewing red union Separate wires apart for potting
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
6. Put Hub on enclosure 7. Tighten Gland Nut
