    I have an old sq.D panel CAT. QON-12M. Is it possible to purchase tandem breakers for this panel? I need to add more circuits.

    panel

    The schematic inside the cover will usually tell you if they will fit, but normally if it can use tandem breakers the model would end in two numbers. One is the total standard breakers and the other is the maximum using tandem breakers. The difference between the two numbers is the number of tandem breakers possible.
