A panel rated for 20 circuits with 20 spaces that has 10 duplex non CTL breakers installed isn't overloaded with circuits but does have equipment installed not listed for the purpose.

Now, I anticipate someone stating that the code allowed for 42 breakers therefore 40 breakers is not more than the code allows, except that the code only allows as many breakers in the panel as the panel is listed and labeled for - which was 20 in the case above, thus more than 20 is "more breaker than is allowed by code and its listing and labeling".
Good information in there, Bill.
