ALNS-350-12-ILSC

Overview

The Ilsco ALNS-350-12-ILSC is a compression-type aluminum-to-copper transition connector designed for joining dissimilar metals. It features a dual-barrel construction with one barrel sized for aluminum conductors and the other for copper, facilitating secure electrical connections between these materials. The device utilizes a compression mechanism to ensure low-resistance joints, addressing galvanic corrosion risks inherent in direct aluminum-copper interfaces.

Feature Summary

• Dual-metal compatibility for aluminum and copper conductors
• Compression-style termination for reliable mechanical grip
• Designed to mitigate galvanic corrosion between dissimilar metals

Applications

• Connecting aluminum service entrance cables to copper busbars
• Transitioning aluminum feeders to copper distribution equipment
• Industrial electrical panel wiring where mixed metal conductors are present

Procurement Notes

Verify that the specific conductor sizes match the connector's rated range before procurement. Confirm that the compression tool used is compatible with the barrel geometry. Ensure the installation environment does not exceed the connector's thermal rating. Check for compliance with local electrical codes regarding dissimilar metal transitions.

Selection Notes

Select this connector when transitioning between aluminum and copper conductors of specified gauges. Ensure the application requires a compression-style termination rather than a set-screw type. Verify that the environmental conditions align with standard indoor or outdoor ratings unless sealed variants are specified. Match the conductor insulation removal length to the barrel depth.

Part Context

Ilsco manufactures a range of compression connectors for power distribution. The ALNS series specifically addresses the need for safe interconnection between aluminum and copper conductors, which is common in retrofitting older aluminum wiring systems to modern copper equipment. This model represents a standard solution for such transitions within their industrial catalog.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for equivalent dual-metal compression connectors from other brands if this specific model is unavailable.
