InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.
Using the COPALUM connector: this article describes the original aluminum wire repair method recommended by the US Consumer Product Safety Commission as an alternative to re-wiring, using the special AMP TYCO COPALUM high-torque crimp-on connector. This discussion
is followed (on the next page - page 12) by an alternative repair method for aluminum wiring which may be useful where the AMP COPALUM special connector and electricians trained to use it
are not available.

Procedures for Using the AMP/TYCO COPALUM Connector for Aluminum Wire REpairs, Evaluation, Comments, Details
This is Aluminum Wiring Repair Procedure - Page 11 Color photos and descriptive captions from CPSC Meeting 9/28/95. This document presents color photos and descriptive captions from aluminum wiring repair methods discussed at the CPSC Meeting 9/28/95.
In this document aluminum wire twist-on connector failures and repair procedures are described,including aluminum wire repair methods which work and methods which do not work and are unsafe.
Color photos of aluminum wire repair procedures, and photos of failed connectors are included.
This document series describes hazards with existing aluminum wiring repair products, explains the aluminum wiring failure mechanism,
and reviews recommended retrofit procedures including use of readily-available materials. This information was presented to the US Consumer Product Safety Commission by Dr. J. Aronstein, 9/28/95.
The minutes of that meeting were obtained under the Freedom of Information Act and posted by Daniel Friedman January 1996.
33. This connector, the AMP COPALUM, is the one recommended by the CPSC for the pigtailing application.
The connector is applied using special tooling and is only available with installation by
specially-trained electricians.
 34. Here is an illustration of the pigtailing method using the COPALUM connector.
NOTE: Details about the COPALUM connector are now presented at ALUMINUM WIRE COPALUM.
