Help with breaker panel
So I just recently purchased a house that was built in the 70s and most of the house has aluminum 12/2 wire ran through the walls. I know the hazards behind aluminum so I’m trying to be cautious with it because I can’t afford to fully gut the house and rewire it all. I have added pigtails to some of the outlets using aluminum to copper wire nuts. I was doing research and chat gbt told me it would be a good idea to upgrade my breakers to arc fault breakers due to the aluminum wire ran in the house. I was just wondering what a real electrical would recommend. Theses are the two breaks I found that would most likely work with my panel. I am just wondering if it’s a good idea. As of right now I just have standard breakers which are not arc or gfci protected. I’m just worried of an electrical fire.
Here are the breakers
ABB THQL1120DFA — 20A dual-function AFCI/GFCI
ABB THQL1115DFA — 15A dual-function AFCI/GFCI
Attached is my panel
