Tandem Breakers

[RiverdaleWG]

Hello,
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?

Thanks

For the best answer, ask the manufacturer of the panel. (Get it straight from the horse I say!)...

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.
