Is it possible to tell from labels if the breakers are AFCI / GFCI in the main panel?
First, none of you current breakers are GFCI or AFCI. If they were, they would have a &quot;Test&quot; button.
Second, you will not be able to fit enough AFCI/GFCI breakers in your panel, even if the panel can take them. This is because your panel is full of tandem (half-width) breakers and there are, to my knowledge, no current AFCI or GFCI breakers in that form-factor. The internal electronics takes up too much space.
If you want to update your breakers, you will have to replace your panel with a larger one.
Edit: as Harper noted in his answer, the other option is to add a new subpanel fed off of the current panel and move most or all of the circuits to the new subpanel. The advantage is that the sub can be installed safely by turning off the main in the existing panel. Replacing the panel would require your power company come and pull the meter to allow the existing panel to be replaced, at a higher cost. (This assumes you do not have a disconnect breaker at the meter. If you do, the advantage disappears.)
