Product review (4 stars): Receptacle received was for copper wire only...picture shows copper or aluminum (AL CU)...,
Picture on Amazon website shows this receptacle is suitable for either copper or aluminum; however, the receptacle I received was for copper wire only. Morris needs to make sure the picture of their product on Amazon matches the one shipped to the customers. The receptacle looked well made so I gave it 4 stars but unfortunately I couldn't use it since my home has aluminum wire for the electric dryer circuit. If your house has copper or copper clad aluminum wire you will have no issues with this receptacle.
