How to Install NSI Copper Compression Connectors
Install and crimp NSI copper compression lugs or splices on concentric, compressed, or compact copper conductors. Select the correct connector size, prepare the conductor properly, and crimp using an approved tool and die set.
Estimated time: 20m
Tools needed:
Wire stripper, Wire brush, Approved compression crimp tool, Approved dies for the selected connector, NSI M-250 or NSI M-500 mechanical crimp tool (for applicable cable sizes), NSI N12ID dieless crimp tool or NSI N1240 tool (optional, where applicable)
Supplies needed:
Correct NSI copper compression lug or splice connector, Copper conductor cable, Oxide-removal cleaning supplies if needed
- Select the correct connector
Choose the proper NSI lug or splice connector for the cable size and conductor type. Verify that the connector series and barrel style match the application before starting. Do not use a connector that does not match the conductor size.
- Strip and clean the conductor
Carefully strip the insulation from the conductor without nicking the strands. Strip enough length so the conductor will fully insert into and fill the connector barrel. Wire brush the stripped conductor to remove oxide films, and keep the exposed copper clean.
- Insert the conductor fully
Insert the cleaned conductor completely into the connector barrel. Verify that the stripped portion is fully seated and that no strands are left outside the barrel. Ensure the conductor is clean and properly aligned before crimping.
- Crimp with the approved tool
Crimp the connector using an approved UL-listed tool and die set for the selected connector series. Follow the barrel markings for suggested crimp locations when using NSI N12ID or N1240 tools. Use the correct number of crimps for the connector type, and apply twice as many crimps for long-barrel lugs and splices as indicated. Use only approved tools and dies for the cable size.
- Verify the finished connection
Inspect the completed crimp to confirm the connector is secure and the conductor is fully retained. Check that the crimp locations match the connector markings and that the installation is suitable for the conductor size. If the connection is not fully seated or properly crimped, remove it and reinstall with the correct connector and tool.
