7.1 Clean the exposed conductor using a wire brush. Place the coppertop (bimetal) connector on the conductor. Make

sure threaded hole in connector faces the apparatus bushing. Crimp the connector in place using a tool and die
combination listed in Table 2. Start crimping just below the knurled line and rotate each successive crimp to prevent
bowing. Do not overlap crimps. Place as many crimps on the connector as will fit.
• Clean excess inhibitor grease from coppertop connector by wiping toward threaded eye.
• Clean cable insulation with solvent pad(s) from 3M CC-3 Cable Cleaning Kit. Do Not allow solvent to touch cable

semi-con.

Note: If use of an abrasive cloth is necessary, use an electrical grade (non-conductive) abrasive. A 120 grit

abrasive is recommended.

7.2 Slide Cold Shrink assembly over cable with loose core end leading (away from cable end). Temporarily position it

just beyond prepared cable end.

7.3 Apply a thin coating of silicone lubricant to the cable insulation.

• Clean and lubricate the cable entrance of the elbow.
• Place elbow on cable. With a twisting motion, push elbow onto cable until threaded eye of coppertop connector is

aligned with the elbow.

7.4 By hand, thread loadbreak probe into threaded eye of coppertop connector. When tight, use the provided installation

tool to properly torque the loadbreak probe. Proper torque is applied when the tool achieves a 180

o

permanent set.

Note: If a different installation tool is used it must apply a torque of 110 in-lbs to achieve proper installation.
