How to Install 373 J2, J3, J4 Loadbreak Junctions

Complete installation guide for universal mounting of two-, three-, and four-point loadbreak junctions on flat or curved surfaces, with adjustable mounting angles from 0 to 90 degrees. Ensure all apparatus is de-energized before beginning installation to prevent serious injury or death.

Estimated time: 1h

Tools needed:

Wrench or socket set, Wire strippers, Hotstick (for voltage test), Suitable voltage sensing device (for capacitance test points)

Supplies needed:

Lubricant (supplied with junction), Mounting bolts (17/32 inch / 13mm diameter, user-supplied), Grounding wire (No. 10 Solid to No. 1 Stranded), HV insulated cap(s) or connector(s) (for unused interfaces)

  1. Prepare for Installation and Safety Check

    DANGER: All apparatus must be de-energized during installation or removal of parts. Inspect all components for damage, proper rating, and compatibility with mating parts. Check the package contents to ensure completeness and read all instructions before starting. Have all required tools at hand and maintain cleanliness throughout the procedure.

  2. Position and Mark Mounting Brackets

    Loosely attach the universal mounting brackets to the junction back plate. Place the entire assembly against the desired mounting surface (flat or curved wall). Adjust the brackets for proper alignment and mark their exact location on the wall for later mounting.

  3. Mount Brackets to Wall

    Detach the universal mounting brackets from the junction back plate. Mount the brackets securely on the wall according to the marks made in Step 2. Note that one or both brackets can be inverted to adjust the distance between bolt centers. Use user-supplied bolts that fit the 17/32 inch (13mm) diameter holes.

  4. Attach Junction Assembly to Brackets

    With the universal mounting brackets securely fastened to the wall, attach the junction back plate (with the junction already attached) to the mounting brackets. Ensure that the parking stands are in the upright position during this process.

  5. Adjust Mounting Angle

    Adjust the mounting angle of the junction to the desired position. The mounting angle is adjustable from 0 to 90 degrees, either above or below the horizontal, in 15-degree increments.

  6. Secure All Bolts

    Tighten all bolts securely to ensure there is no movement of the junction assembly during operation. Verify that all connections are firm and stable.

  7. Ground the Back Plate

    Ground the back plate of the junction. A grounding lug is provided for this purpose, which accommodates grounding wire sizes from No. 10 Solid to No. 1 Stranded. Ensure a proper and secure ground connection.

  8. Install Mating Products and Cap Unused Interfaces

    Thoroughly wipe the bushing interface clean of any contaminants and lubricate it with the supplied lubricant. Install the mating products (e.g., elbow connectors) to the bushing insert following their specific installation instructions. WARNING: If all operating interfaces are not utilized, an Elastimold 375DR insulated cap or appropriate HV insulated connector MUST be installed on the unused interface(s) before energization. Do NOT use protective shipping covers for this function.

  9. Perform Voltage Test (Post-Installation)

    If performing a voltage test, remove the test point cap with a hotstick, peeling it off at an angle. WARNING: The voltage test point is a capacitance device; do not use conventional voltage measuring equipment. Use a suitable sensing device designed for capacitive test points and follow its manufacturer’s directions. Contamination or incorrect equipment can give a false 'no voltage' indication. Treat the elbow as energized until confirmed by other means. After testing, clean and lubricate the inside surface of the cap with silicone grease and replace it on the test point.
