striker1 Posted February 27, 2012 Report Share Posted February 27, 2012 When were devices for plugs and switches for aluminum wiring made Quote Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted February 27, 2012 Report Share Posted February 27, 2012 I believe they first appeared in the late 1960's. The early devices were labeled with CU/AL. The early switches/receptacles with the CU/AL specification did not work well and a new specification noted as CO/ALR (Copper/Aluminum Revised) was implemented. The new specification/design was better at dealing with the aluminum wiring. Bottom line ... late 1960's. Quote Link to comment Share on other sites More sharing options...
