Electrically Challenged

[Cazoom]

okay the new box looks okay.. can't tell the total load (stated as 125 but usually 100 or 200??)
to get more to the bedroom in new place you are going to have to run new wires..plugs .and a new breaker.. it ain't gonna be cheap...AND
you are gonna have to check your condo rules to see if you are allowed to do so....first....it sucks owning the living space but not able to do as you choose to it!!!check first..!!
and in your place you are in now!!!! The box states on the sticker 70 amps...correct!
if that is right and you calculate 90 amps in fuses.. you are at risk of an overload and fire...it should be 70 amps of fuses max...
doesnt matter if there are empty spots.. the total amp must not be overfused and it is!!! do that to your car and you burn wires!!!
i'd have it checked...
