I need to replace existing 100Amp subpanel with another panel that has more spaces and i think the only way i can go is to put in 125 panel with more circuit capacity.However i will keep the main at 100Amp. So i will have a 125Amp panel with more circuit capacity.
I do not think this is a good idea but i also think there will be no harm because the main in the switch gear room for this condo is still 100Amps and main subfeed is still #2 copper.
By doing it this way i am gaining more spaces for two more circuits.
What are your thoughts.If i am wrong please give NEC and the year.
Merci
Edward
