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.)
