200A Service and subs


I have a 200A service panel powering a 60A Sub and a 100A sub. They all have 20A circuits. The main has one 30A and the 100a sub has one 30A circuit. Theres a new addition to the 2nd floor that will require only 20A circuits. Will it be okay to put another sub panel in there running from the 100A subpanel?

it all depends on what your total loads are and your concurrent loads are.

Technically and theoretically, you could add as many subs as you want. Practical applications get in the way when your concurrent loads exceed the circuit that feeds the panel.
