Re: Twist-On Connectors for Aluminum Wiring

Dear Dr. Aronstein:

In answer to your recent inquiry, the U.S. Consumer Product Safety Commission (CPSC) staff does not consider the use of the twist-on connector (including the Ideal No.65) to be a suitable repair for aluminum wiring in residences.

Acceptable repairs are those identified in the CPSC publication "Repairing Aluminum Wiring" (copy enclosed).

Sincerely,

William H. King, Jr.
Director
Division of Electrical Engineering
