Two--, Three-- , and Four--Point Loadbreak Junctions
CONTENTS: Loadbreak Junction with Holdown Brackets and Hardware (as required), Shield Plate, Installaion Instructions.
The two --- , three--- , and four--- way loadbreak junctions are used for sectionalizing, looping, tapping or for apparatus change
out. These junctions provide interconnected apparatus interfaces for Elastimold 25kV class (15.2kV phase ---to ---ground
and 26.3kV phase---to--- phase) loadbreak connectors. A yellow band provides indication of fullelbow seating and also provides vents for improved switiching performance. This product is identified by a round yellow marker supplied with this kit.
Remove the adhesive backed marker and attached it to the mounting surface when it will be visable to operator.
DANGER
All apparatus must be de--energized during installation
