    I have a 100A Siemens panel with 20 breaker positions. It currently has 2 tendem breakers installed.
    I want to add a few extra circuits in my basement. How many additional tandem breakers can be added?

    Need the model number of the panel, to answer that.

    Example: Siemens model #G3040B1200CP.

    Has 30 spaces (#G3040B1200CP)

    Can have 40 circuits (#G3040B1200CP)

    ... so, a max of ten tandem breakers.
