Page 5: Prepare Cables
Prepare Cables 2.1.1 Prepare cables according to standard procedures. Refer to template provided or illustration below for proper dimensions. Additional distance is required on one cable to provide extra neutral wire length for connecting the neutrals. 13" (330 mm) 13" (330 mm) 4 1/2"... - Page 6 2.1.2 JCN: Carefully bend neutral wires back over edge of cable jackets. Press them against cables and temporarily secure with vinyl tape. For CN splices with exposed neutral connections: Carefully bend neutral wires back over binding (wire or tape). Press them against cables and temporarily secure with vinyl tape.

Page 8: Install Splice
Install Splice 2.2.1 Install connector. See table (on cover) for proper connector dimensions. (For standard 3M™ connectors, refer to table at the end of this instruction for crimping information) 2.2.2 Apply a tape marker to semi-con insulation shield on cable which does not contain splice. - Page 9 2.2.4 Clean cables using standard practice: a. Do not use solvent or abrasive on cable semi-conductive insulation shield. b. If abrasive is used on cable insulation, do not reduce diameter below the 1.07" (27,2 mm) minimum specified for the splice. 2.2.5 Apply red compound on cable insulation, making certain to fill in edge of cable semi-cons.

2.4.3 Continue to install the cold shrink tube over the rubber mastic on the other cable by slowly pulling and unwinding the outer core counterclockwise. This portion of the cold shrink tube installs differently than typical cold shrink products in that as the tube shrinks, the end rolls under. The tube may need a slight push to get over the second mastic seal. -
Page 13: Install Jacket For Cn Splices
For CN to CN Splices Note: If grounding splice, leave sufficient neutral wire length to extend neutral wires through the inline compression connectors for connection to the ground wire per Wisconsin Electric specifications. 2.5.2 Connect the neutral wires using inline compression connectors. The neutral wires should pass through the connector, making an overlap crimp. - Page 14 For CN to CN Splices 2.6.2 Begin to install the cold shrink tube by completely covering the rubber mastic, and slowly pulling and unwinding the inner core counterclockwise toward the splice body. The outer core should remain relatively stationary while unwinding the inner core. If the outer core begins to move towards the first mastic seal, gently pull the outer core and jacketing tube towards the second mastic seal and continue unwinding the inner core.
