3 necessity an Be the Mother of innovation A large industrial plant in the Gulf oast was partially shut down due to a broken underground electrical line. The 5kv wire was installed in 4 PV coated conduit. After a two week shut down and a lengthy investigation, it was determined that the conduits were not screwed together properly. The conduit threads had only engaged 1 to 2 threads of the coupling. The installer didn t have a way to verify the integrity of the conduit connection. O Kote s O Guard Marking System (patent pending) insures a proper thread connection every time in the field and is easily inspected even after installation. When the Yellow Mark disappears into the sleeve, you know there are five threads engaged per NE Article 500.8(E). Make sure your PV oated onduit material has the O Guard mark! orrosive elements cause millions of dollars in damage through lost time, materials and labor. Regardless of the materials used to combat these corrosive forces, they are only as good as the quality of the installation. In electrical conduit systems, improper installation of the raceway or fittings can cause expensive downtime and potential injury. Performing the proper installation insures that the installed system is SAFE. o kote PV oated onduit and Fittings has the answer to your safe raceway installation. The O Guard Marking System (patent pending) on every piece of O kote PV oated onduit allows visual verification that conduits are properly threaded into couplings and fittings. The O Guard Marking System (patent pending) is also installed on every O kote PV oated Elbow

4 installation ProEdurEs o kote recommended installation Procedures PV coated conduit is installed in much the same manner as conventional rigid galvanized steel conduit; however, certain precautions must be taken to compensate for the exterior coating and to assure satisfactory results. By following these guidelines and using the proper tools, a damage-free installation can be obtained. When installing PV coated conduit or elbows into couplings, PV coated fittings or threaded enclosures, it is imperative that the threads be engaged five turns into the receiving hub, per NE article 500.8(E). O kote s O Guard Marking System (patent pending), on full lengths of conduit and elbows allows visible field verification that five threads are engaged. It is recommended that a yoke vise be used in the field for clamping PV coated conduit. When using a yoke or any other vise, it is recommended that hardened steel jaws be replaced with adapters that provide greater clamping force to prevent the pipe from spinning during the threading operation. To hold PV coated conduit in any other vise, take two pieces of rigid conduit one size larger than the conduit to be threaded 6-8 long. Using a band saw, slice them lengthwise slightly off center. Use the smaller pieces as a shell around the conduit (throw away the large ones). This will grab onto the large area, allowing a strong grip without damage to the coating. It is preferred that a roller type cutter be used in cutting the conduit as it results in a 1/4 exposed area of pipe before the start of the PV jacket. This will allow the threader dies to engage the conduit easier and lessen pressure at the clamped area. A hacksaw or band saw will result in a flush cut of the PV and conduit. In this instance it is recommended to taper-trim the PV starting at 1/4 from the cut. This pencil-cut will allow the threader dies to engage more readily. If the end is not trimmed, additional pressure will be required to engage the dies. Use a reamer to remove any burrs or sharp edges caused by the cutting operation O Kote offers an electric bender manufactured to accept 1/2 through 2 PV coated conduit, allowing damage free bending. For 2 1/2 and larger sizes, a hydraulic bender is recommended. Shoes especially designed for PV coated conduit are available from most manufacturers. If existing rigid hydraulic shoes (not EMT) are to be modified, acceptable results can be obtained by machining.060 from the inside area of the shoe. Threading PV coated conduit with RIDGID hand dies requires modification to the dies. The inside diameter of the pipe guide to the die head must be machined out.120 to compensate for the PV coating. Factory modified die heads are available from your distributor. After new threads have been cut, it is important that corrosion protection be applied to the exposed metal. Use a de-greasing spray to thoroughly clean the threads and internal ream. Then apply a conductive corrosion inhibitor liberally to the threads per NE article 300.6(a). U L US

RA clamps shall have a minimum of.040 (40 mils) coating throughout. All nuts for RA clamps and U-bolts shall be encapsulated in a hexagon shape to fit standard sockets. Hardness Shore A General Properties for O Kote PV oated Galvanized onduit and Fittings Dielectric Strength cycles Aging 1,000 hours Atlas Weatherometer Elongation 200% Temperature The polyvinyl chloride compound shall conform at -10 degrees Fahrenheit temperature to Federal Specifications LP-406b, Method 2051, Amendment 1 of 25 September 1952 (ASTMD-746). O Kote brown is not recommended for use in areas where it will be exposed to sustained temperatures of 200 degrees Fahrenheit or exposed to fire. Flammability If subjected to sustained flame or sustained heat above 400 degrees Fahrenheit, PV will burn. PV is self-extinguishing at room temperature. Toxicity Prolonged exposure to heat greater than 200 degrees Fahrenheit or exposure to fire may cause the plastic coatings to release harmful emissions posing a potential health hazard to persons subjected to such emissions. Bonding Test Using a sharp knife, make two parallel cuts through the coating 1/2 apart and 4 long. Make a cut connecting those two cuts and work with a knife underneath the plastic to free a plastic tab. The tab shall be pulled with a pair of pliers away from the pipe. The tab should tear leaving particles of plastic on the metal surface of the conduit indicating the bond is stronger than the tensile strength of the coating O kote Inc.
