How to Install a K650J4-6 Deadbreak Junction (Universal Mount)
This guide provides step-by-step instructions for installing a K650J4-6 two-, three-, or four-point deadbreak junction using the universal mount method. Ensure all apparatus are de-energized and installation is performed by competent personnel trained in high voltage electrical equipment.
Estimated time: 1h
Tools needed:
Wrench/Socket Set (for 3/8" and 1/2" hex nuts/screws), Wire Strippers
Supplies needed:
Deadbreak Junction, Base Bracket, Base Plate, Universal Brackets, Mounting Hardware Prepack, Suitable Fasteners (for initial bracket mounting), Grounding Wire (No. 2 solid to 1/0 stranded), ELASTIMOLD Approved Lubricant, HV Insulated Caps
- Determine Mounting Location and Mark Slots
Ensure all apparatus are de-energized. Select the desired location for the junction assembly. Use the base plate as a template, place it on the mounting surface, and mark all slot locations for drilling or fastener placement.
- Attach Initial Universal Brackets
Secure two (2) universal brackets to the flat mounting surface using suitable fasteners. Tighten these fasteners securely to prevent any movement during operation.
- Attach Remaining Universal Brackets
Connect the remaining two (2) universal brackets to the two (2) universal brackets already mounted on the surface. Position them at the desired angle and secure them using the supplied hardware (3/8" hex head cap screw, external tooth lock washer, and 3/8" hex nut). Tighten securely.
- Assemble Junction to Base Bracket and Base Plate
Attach the deadbreak junction to the base bracket assembly and base plate. Use two (2) 1/2" hex head cap screws, two (2) 1/2" split lock washers, and two (2) 1/2" hex nuts, securing them to the center mounting holes on the bracket assembly. Tighten securely.
- Mount Junction Assembly to Universal Brackets
Attach the assembled deadbreak junction to the universal brackets using the supplied hardware (1/2" hex head cap screw, 1/2" split lock washer, and 1/2" hex nut). Ensure the parking stand is in the upright position before tightening securely.
- Ground the Assembly
Connect a grounding wire (accommodating No. 2 solid to 1/0 stranded) to the grounding lug provided on the base bracket. Ensure that both the base bracket assembly and the junction's black conductive jacket are properly grounded.
- Prepare Operating Interfaces
Remove all protective shipping caps from the operating interfaces and clean them thoroughly. Lubricate each interface with an ELASTIMOLD approved lubricant; do not substitute. If any operating interfaces are not utilized, install appropriate HV insulated caps on the unused bushings before energizing the circuit.
