Ecm Industries Llc GSPA-2N Aluminum Reducer Splicer 2-14 Awg

Product Description

The ECM INDUSTRIES LLC GSPA-2N is a dual-rated aluminum reducer and splicer connector designed for joining aluminum and copper conductors in wire splicing applications. Each pack contains 2 connectors rated for wire gauges ranging from 2 AWG to 14 AWG maximum. An internal wire stop is built into each connector to limit galvanic corrosion by preventing direct metal-to-metal contact between dissimilar conductors. This design addresses one of the most common failure points in aluminum-to-copper connections. Licensed electricians and electrical contractors install these connectors in branch circuit and service wiring where mixed-metal conductor splices are required.

These dual-rated splicer connectors are suited for residential and light commercial electrical installations where aluminum wiring meets copper conductors. Typical applications include service entrance work, panel feeders, and branch circuit splices. The dual-rating means the connector is listed for use with both aluminum and copper wire, making it a code-compliant solution for retrofit and new construction work. Each pack of 2 is sold as an individual unit, with 6 packs available per package quantity.

Key Features

• Dual-rated for use with both aluminum and copper conductors
• Accepts wire gauges from 2 AWG to 14 AWG maximum
• Internal wire stop limits galvanic corrosion by preventing direct contact of dissimilar metals
• Sold in a 2-pack configuration for convenient single-splice applications
• Reducer design accommodates transitions between different wire gauges

Compatibility

Designed as an OEM-style replacement and standard-fit connector for aluminum-to-copper wire splicing applications in residential and commercial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for aluminum conductor terminations and splices. Power must be shut off at the breaker and verified de-energized with a meter before making any connections. Do not over-torque the connector body, and confirm the internal wire stop is properly engaged before completing the splice. Follow connector manufacturer seating guidelines to ensure full conductor insertion.
