This question is kind of a follow up to a question I had about installing a new oven. I know the CU/AL topic has been addressed on this site, but I need to know about CU/AL connections for larger wires. Basicaly, since I'm swaping my old 40amp breaker for a 30amp one, I will need to connect the old #6 AWG AL wire to #10 AWG copper. The guy at the electrical supply store gave me multi tap connectors to do this. The kind that look like this: http://images.grainger.com/B333_27/i...1YRJ2_AS01.JPG I know that I'll need to use a oxide inhibitor also. I just want to make sure this connection is "kosher" or if anyone advises something else.
