What interface spacing options are available?
The junctions offer standard 4'' spacing or an optional 6.5'' spacing for interfaces.
What does the Tilt Mounting Adapter (TMA) do?
The TMA bolts to the standard mounting bracket, providing an adjustable angle of 15, 30, 45, or 60 degrees. Two adapters are required for this option.
How should 200 Amp and 600 Amp interfaces be ordered?
When a junction has both 200 Amp and 600 Series interfaces, always start with the 200 Amp side when specifying.
Where can these multipoint junctions be installed?
ELASTIMOLD junctions are designed for subsurface, vault, or padmount applications. They feature a fully shielded and fully submersible molded rubber housing.
Can the junction be installed in submersible environments?
Yes, the junction features a fully shielded and fully submersible molded rubber housing.
How to Install a Deadbreak Junction with Universal Mount
This guide provides step-by-step instructions for installing a two-, three-, or four-point deadbreak junction using the universal mounting method. It covers mounting, assembly, and grounding procedures for safe and effective installation.
Estimated time: 45m
Tools needed:
Wrench set (3/8 inch and 1/2 inch), Marking tool, Wire strippers (for grounding wire)
Supplies needed:
Deadbreak Junction, Base Bracket, Base Plate, Universal Brackets (4), Mounting Hardware Prepack, Fasteners (suitable for mounting brackets to surface, user-supplied), Grounding wire (No. 2 solid to 1/0 stranded), ELASTIMOLD approved lubricant, HV insulated caps (if required)
- Prepare for Installation and Ensure Safety
Before beginning, ensure all apparatus is de-energized. This product must be installed only by competent personnel trained in high voltage electrical equipment safety practices. Inspect all parts for damage, correct rating, and compatibility with mating parts. Failure to follow safety instructions can result in serious injury or death.
- Determine Mounting Location and Mark
Determine the desired location for the junction assembly. Use the base plate as a template, place it on the mounting surface, and mark the four slot locations where the universal brackets will be attached.
- Attach Initial Universal Brackets to Surface
Secure two (2) universal brackets to the marked slot locations on the flat surface using suitable fasteners (user-supplied). Tighten them securely to prevent any movement during operation.
- Attach Remaining Universal Brackets
Attach the remaining two (2) universal brackets to the two (2) universal brackets already mounted on the surface at the desired angle. Use the supplied 3/8” hex head cap screws, external tooth lock washers, and 3/8” hex nuts. Tighten securely.
- Assemble Junction to Base Bracket and Plate
Assemble 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, attaching 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 1/2” hex head cap screws, 1/2” split lock washers, and 1/2” hex nuts. Ensure the parking stand is in the upright position and tighten all hardware securely.
- Ground the Assembly
Ground the base bracket assembly and the junction’s black conductive jacket. A grounding lug is provided on the base bracket for this purpose. It accommodates wire sizes from No. 2 solid to 1/0 stranded. Connect the appropriate grounding wire securely.
- 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 with other lubricants, as they may harm the product or its mating products.
- Install Insulated Caps (if needed)
If not all operating interfaces will be utilized, install appropriate HV insulated caps on the unused bushing(s) before energizing the circuit. Do not use the protective shipping caps for this function, as they are not insulated and are only for handling and installation.
