Ecm Industries Llc GSPA-0N Aluminum Dual Rated Reducer Splicer

Product Description

The ECM INDUSTRIES LLC GSPA-0N is a dual-rated aluminum reducer and splicer connector designed for joining conductors ranging from 14 AWG up to 1/0 AWG. It accommodates both aluminum and copper wire, making it a practical solution for mixed-metal wiring situations common in residential and light commercial electrical work. An internal wire stop limits galvanic corrosion by preventing direct contact between dissimilar metals inside the connector. Electricians use this fitting to terminate or splice branch circuit and feeder conductors where aluminum wiring interfaces with copper systems.

This connector suits residential panel feed applications, service entrance work, and retrofit installations where aluminum feeders connect to copper branch circuit wiring. Its dual-rated construction means it meets requirements for both aluminum and copper conductor terminations without the need for separate fittings. The 1/0-14 AWG range covers a wide spread of conductor sizes, reducing the number of connector types a technician needs to carry on the job. Each package contains 6 pieces.

Key Features

• Dual-rated for both aluminum and copper conductors in the same connector
• Accepts conductors from 14 AWG up to 1/0 AWG maximum
• Internal wire stop limits galvanic corrosion by preventing dissimilar metal contact
• Aluminum body construction suited for use with aluminum feeder conductors
• Sold in a 6-piece package for multi-connection jobs

Compatibility

Designed as an OEM-style replacement and general-use dual-rated reducer splicer for aluminum-to-copper conductor connections in residential and light commercial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for aluminum conductor terminations. De-energize the circuit at the breaker panel and verify zero voltage with a meter before making any connections. Apply listed antioxidant compound to aluminum conductors before inserting into the connector, as required by applicable code. Do not exceed the 1/0 AWG maximum conductor size rating.
