Installation Instructions
1.0 General
The 3M
™
Industrial Loadbreak Elbow connector is a fully-
shielded and insulated plug-in termination for connecting
underground cable to transformers, switching cabinets and
junctions equipped with loadbreak bushings. The elbow
connector and bushing insert comprise the essential
components of all loadbreak connections.
The coppertop (bimetal) compression connector is a
standard item to transition from the cable to the loadbreak
probe. An aluminum crimp barrel is inertia-welded to a
copper lug. The aluminum barrel makes the connector
easy to crimp and the copper lug ensures a reliable, tight,
cool operating connection with the loadbreak probe.
2.0 Installation
Cable stripping and scoring tools, available from various
tool manufacturers, are recommended for use when
installing loadbreak elbows. After preparing the cable and
installing shield adapter, the elbow housing is pushed onto
the cable. The loadbreak probe is threaded into the
coppertop connector using the supplied installation tool or
an approved equivalent. Use a shotgun stick to perform
loadmake and loadbreak operations. (See page 10 for
operating instructions.)
