- Follow all safe work practices and recommended work procedures.
- Review instruction sheet. Form cable, with no sharp bends, to the bushing. Terminate the metallic shield (neutral) as close to the separable connector as possible. Do not expose more of the semi-con than is recommended.
- Do not nick or cut the shield, insulation or conductor when preparing the cable. This can lead to over-heating and dielectric failure.
- Wire brush the conductor before inserting it into the compression barrel. Aluminum wire starts to oxidize immediately when exposed to air. Always wire brush every connection.
- Do not remove the inhibitor from inside the compression barrel. It is there to help break up the oxide film and improve current transfer.
- Use the correct tool and die and make the recommended number of crimps when installing the compression connector. Rotate successive indents 90 degrees or 180 degrees to prevent distortion.
- Remove all semi-con residue, inhibitor and other contaminates from insulation with HV cable cleaner. Apply lubricant to the cable insulation. Only use supplied lubricant or Hubbell SL150 (5oz tube). Other lubricants may leave elbows stuck.
- Do not apply lubricant to the threads of the compression connector or the elbow probe. Keep lubricant free of dirt and grime.
- Align connector with bushing before crimping. Do not attempt to correct misalignment by twisting the connector. Can birdcage the conductor and lead to overheating.
- Keep the probe follower tip clean. The white ablative material on the tip aids in extinguishing arcs. Any contaminants can reduce its effectiveness. Hand start probe into the compression connector to prevent cross-threading.
- Tighten the probe with supplied wrench until it yields, indicating proper torque has been applied.
- An estimated 50% of all cable failures come from improper cable prep.
