Range 5 kV Conductor Size Range (AWG & kcmil) 8 kV 15 kV 25/28 kV 7652–S–4 0.64 – 1.08 (16,3 – 27,4 mm) 0.97 – 1.
Instructions for Jacketed Concentric Neutral (JCN) Cable 2.0 Prepare Cable 2.1 Check to be sure cable size fits within kit size range as shown in Table 1. 2.2 Train cable into position and cut to length required for installation. Allow sufficient neutral wire length for grounding connection. 2.3 Prepare cable using dimensions shown in Figure 1. BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG.
2.5 Bend neutral wires back over applied sealing mastic and secure to cable jacket 4 1/2" (114 mm), below cable semi-con edge using vinyl tape (Figure 3). NOTE: Position vinyl tape with care, it also serves as a marker for positioning the termination. 2.6 Select second Scotch® Mastic Strip 2230 from kit and remove white release liners. Apply a second SINGLE WRAP of mastic over the neutral wires and previously applied mastic (Figure 3). Cut off excess. 2.
4.2 If abrasive must be used: a. Use on insulation only. DO NOT USE ABRASIVE ON SEMI-CON INSULATION SHIELD! b. Use only aluminum oxide abrasive; grit 120 or finer. c. Be careful not to reduce the cable insulation diameter below that allowed by the kit. 5.0 Install Termination 5.1 Slide the termination body onto the cable and remove core. Pull while unwinding counterclockwise starting with the loose end (Figure 5).

Instructions for Concentric Neutral (CN) Cable 6.0 Prepare Cable 6.1 Check to be sure cable size fits within kit range as shown in Table 1. 6.2 Train cable into position and cut to length required for installation. Allow sufficient neutral wire length for grounding connection. 6.3 Prepare cable using dimensions shown in Figure 7. BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG.
6.6 Bend neutral wires back over applied sealing mastic and secure to cable 4 1/2" (114 mm), below cable semi-con edge using vinyl tape (Figure 8). NOTE: Position vinyl tape with care, it also serves as a marker for positioning the termination. 6.7 6.8 Select second Scotch® Mastic Strip 2230 from kit and remove white release liners. Apply a second SINGLE WRAP of mastic over the neutral wires and previously applied mastic (Figure 8). Cut off excess.
.0 Install Termination 9.1 Slide the termination body onto the cable and remove core. Pull while unwinding, counterclockwise, starting with the loose end (Figure 10). Make sure the termination body (not the core) is butted up to the edge of the vinyl tape marker previously applied (Figure 10). NOTE: Once the termination body makes contact over the mastic seal area, there is no need to continue supporting the assembly. DO NOT PUSH OR PULL ON THE TERMINATION ASSEMBLY WHILE UNWINDING THE CORE.
