Proper training is an important aspect when using termination tools. Lori Alario, technical application specialist for Greenlee, teaches several classes at the Greenlee Product Training School. She offers these cable termination safety tips:

To ensure a proper and strong crimp, do not use a connector that does not fit the cable. Connectors are designed to match a specific cable size. You want to confirm the connector is marked for the conductors’ size, color code, or die index.

Once you’ve matched the connector to the cable, the proper die should be selected to crimp the installation by matching the die index number or color code to the connector. These are numbers, which are typically marked on the connectors, dies and overhead lines.

Remove insulation from cable before crimping.

Be sure to use the correct number and location of crimps required for individual connectors to ensure a proper installation of the cable:

Use:
Copper connectors for copper cable;
Aluminum connectors for aluminum cable; and
Dual-Rated Aluminum connectors can be used for both copper and sluminum.

A periodic pressure relief check of the crimper is recommended using a compression force gauge. This gauge ensures the crimper is reaching the proper pressure required to crimp the connector to the cable.

A pressure gauge is recommended to use in line with hand hydraulic or electric hydraulic pumps to ensure that the driver of choice is reaching the recommended force required to crimp the connector to the cable.

Use the correct torque recommended for Mechanical connectors as specified by the connector manufacturer. Match the tonnage specified by the connector to the crimp tool being used to crimp the connection.

If a cUL Certified crimp is necessary, it is mandatory to use the proper installation tooling and methods as required by the connector manufacturer.

Not all crimp tools are insulated, so be sure to practice proper operation and do not use on a live line. If live line application is acceptable, be sure to use the required protective equipment and clothing. Keep fingers away from jaws of crimp tool when making a crimp, and always wear safety glasses when operating a crimp tool to avoid injury from debris.

Do not operate the crimp tool without dies or die adapters to prevent the crimp head from being damaged.

Inspect tools and make sure they are in proper working order before operating, and read the instruction manual before operating or servicing your crimp tool

Do not use crimp tools for anything other than what they are specified for.

Do not use Industrial Connectors in Overhead Applications or Overhead Connectors in Industrial Applications.
