Aluminum can only be spliced with certain wire nuts, this needs to be repaired by electrician. These do not appear to be the correct kind.

Thanks, What do you think about the #14 copper from the breaker to splice and then the #12 aluminum running up into the wall cavity?

Tim,
Did you catch the fact that this is a Zinsco panel board? The AL/CU splice may be much less critical than the potential defects/deficiencies that are common in Zinsco panels.
Any time you see this type of splice (IMHO), it should be verified by an electrician. Anti-oxidant is required at the splice and the wire nut should be listed for CU/AL.
Strange that they would do this as Zinsco breakers are listed for AL as well as CU.

Thanks Jeffrey,
Yes i did notice the Zinsco panel, I also let them know that they installed the wrong type dead front cover which would not seat properly (Sylvania cover). Thanks for the reminder Jeffrey.
Whats your opinion about the 2 differnet wire sizes?

If I’m not mistaken, the aluminum wire has a decreased current carrying capacity and should be 12 guage to handle the 15 amp current.

I think it IS #12 AL.

The wire size is appropriate for the ampacity. If the connection is made properly, the difference in conductors should not be an issue.
The Sylvania cover was probably correct, just didn't fit properly. Late 70's through early 80's was when Sylvania bought out Zinsco and adopted their garbage. All they did was change the sticker.
The next cross-over was the Sylvania/GTE.
All Zinsco's - just different names.

Oops, missed that. Breaker needs to be replaced.

I do not want to sound stupid or something, but if my understanding is correct, aluminum wiring is always one size up from copper for the same amperage.So, if a 14 gauge copper conductor is fused at 15 amps, the same conductor in aluminum should be 12 gauge and still fused at 15 amps.
Correct me guys, because I am logically confused.
