600 A, 15, 25, and 35 kV Class Cleer Grounding ElbowProduct informationIntroductionThe Eaton Cooper Power series Cleer grounding elbow(Figure 1) is a tool used to provide a visible ground onEaton Cooper Power series 600 A, 15, 25, and 35 kV CleerLoadbreak Connector Systems. It is designed to be installeddirectly on the 600 A loadbreak interfaces after the circuitis verified to be de-energized. A Cleer grounding elbowinstalled on the loadbreak bushing interfaces on each endof the cable will isolate and ground the cable. The groundingelbow has a 16 kA 10 cycle through fault rating for 15 kVsystems.All grounding elbow sets supplied with a factory installedferrule and clamp conform to the latest requirements ofASTM F855. When grounding elbow is ordered withoutclamp, it does not meet ASTM F855. It is the user’sresponsibility to install an approved ferrule and clamp. Forall kits not conforming to the latest ASTM F855 Edition, thecable will be terminated with a blunt cable end.Read this manual firstRead and understand the contents of this manual and followall locally approved procedures and safety practices beforeinstalling or operating this equipmentAdditional informationThese instructions cannot cover all details or variationsin the equipment, procedures, or process described norprovide directions for meeting every possible contingencyduring installation, operation, or maintenance. Whenadditional information is desired to satisfy a problem notcovered sufficiently for the user’s purpose, contact yourEaton representative.Acceptance and initial inspectionEach grounding elbow is completely inspected and testedat the factory. It is in good condition when accepted by thecarrier for shipment. Upon receipt of a grounding elbow,inspect the grounding elbow thoroughly for damage andloss of parts incurred during shipment. If damage or loss isdiscovered, file a claim with the carrier immediately.Handling and storageGrounding elbows and accessories should be stored andhandled in a manner as to prevent contamination to theinterfaces. When not in use, grounding elbows shouldbe stored installed on a mating accessory, such as astandoff bushing.Quality standardsISO 9001 Certified Quality Management SystemCable isolation and grounding instructionsCAUTIONThe Eaton Cooper Power series 600 A Cleer GroundedElbow is designed to be operated in accordance withnormal safe operating procedures. These instructions arenot intended to supersede or replace existing safety andoperating procedures. The grounding elbow should beinstalled and service only by personnel knowledgeableof good safety practices and fully trained on theinstallation and application of high voltage electricalequipment.For product applications that require ratings orcharacteristics not shown, contact Eaton for specificrecommendations.Equipment required (2) 600 A Cleer grounding elbows (2) 600 A Cleer standoff bushings (2) 600 A Cleer insulated protective caps Silicone lubricant Clampstick Installation instruction sheetFigure 1. 600 A, 15/25/35 kV Class Cleer groundingelbow shown with six feet of 600 volt fully insulatedcopper ground cable and clampInstallation Instructions MN650056EN February 20201
600 A, 15, 25, and 35 kV Class Cleer Grounding ElbowVisible break and visible ground using T-OP II orBT-TAP terminationsWARNINGVisibly inspect grounding elbows, cables, ferrules, andclamps prior to installation to ensure they are complete,undamaged, and there is no corrosion or breakage.Damaged or worn grounding equipment can result inequipment failure that could cause property destructionor personal injury.WARNINGAll associated apparatus must be de-energized duringinstallation or maintenance.Step 1Clean and lubricate apparatus Clean and lubricate interfaces of protective caps andstandoff bushings using lubricant supplied or Eatonequivalent.Step 2Install standoff bushing WARNINGHigh Voltage. The Eaton Cooper Power series Cleer 600A loadbreak connector system is not designed to beswitched under water. When operating the Cleer 600 Aloadbreak connector system where moisture is present,such as during a rainstorm, take steps to ensure theconnector interfaces stay dry. Failure to comply couldlead to a fault that may result in death or serious injury.WARNINGHigh Voltage. The operator should always use personalprotective equipment (insulated gloves, clampstickand eye protection) whenever operating the connector.The operator should always be in the best possibleoperating position, providing firm footing and enablinga secure grasp of the clampstick positioned to theside of one’s torso, while maintaining positive controlof the connector before, during and immediatelyafter operation. If there is any question regarding theoperator’s operating position, de-energize the connectorbefore operation. The operator should not be lookingdirectly at the connector during the moment of circuitinterruption or connection. Failure to comply couldresult in death or serious injury. Attach a #14 AWG copper drain wire from the standoffbracket ground lug to system ground.Securely fasten a clampstick to the eyebolt on standoffbushing bracket and use the clampstick to position thestandoff in standoff pocket. Tighten eyebolt againstapparatus wall. Step 3Remove “C” Connector WARNINGHigh Voltage. The Cooper Power series Cleer 600 Aloadbreak bushings from Eaton should only be matedwith other Cleer 600 A loadbreak products. Do notattempt to mate 200 A loadbreak or 600 A deadbreakproducts to Cleer 600 A loadbreak bushings. Failure tocomply could lead to a fault that may result in death orserious injury. WARNINGHigh Voltage. Do not close or pull the Eaton CooperPower series Cleer connector slowly onto or off of thebushings during a loadmake or loadbreak operation.Failure to comply could tease the contacts leading toexcessive arcing causing a fault that may result in deathor serious injury.2Area must be clear of obstructions or contaminants thatwould interfere with this operation.Secure connector operating eye firmly onto clampstickand lock.Thrust clampstick forward until the connector movesapproximately 1/4" (5 mm) further onto the bushings.This action will break any surface friction between outersurfaces of bushings and inner surfaces of connectorinterfaces. The yellow latch indicator rings on thebushings should now be visible in the cuff windows ofthe connector.Looking away from the connector, pull the clampstick andwithdraw the connector from bushings with a fast, firm,straight motion. Minimum amount of travel of connectorto break load is 9" (230 mm).Using the clampstick, move the connector away fromthe bushings and place the metallic portion of oneof the probes directly onto a ground plane. This willdischarge any capacitive charge that may still be on theprobes. Alternatively, the “C” connector can be mateddirectly with the Cleer standoff bushing to discharge anycapacitive charge that may still be on the probe.WARNINGHigh Voltage. If the fiberglass contact tube of one orboth loadbreak bushing(s) extends forward, the unitMUST be replaced. Failure to comply could causethermal runaway failure or failure to successfullyfault-close; this may result in serious personal injuryInstallation Instructions MN650056EN February 2020
