Electrical in a pre-war co-op part II

I recently started a thread re a pre-war co-op I am planning to buy:

Since apt has electric, not gas, to run stoves, I brought in an electrician to assess the situation. Turns out there’s a 40 amp dedicated line for the stove and 40 amps (fuse panel of six 20 and two 30 amp fuses) to power the rest of the apt.

I was doing all this to find out if I could upgrade the electricity supply in order to put in an induction range, but come to find out the very cheap coil stove the sponsor put in when renovating is rated at 48 amps, which is the same amp rating as the induction range I want to put in. (I can’t find any electric or induction stoves rated at less than 45 amps).

So really, now the issue is not can I upgrade, but the fact that all the apartments have 40 amp lines for the stoves and are all almost definitely running stoves rated at 45 amps or higher.

If I switched out the 48 amp electric stove for a 48 amp induction stove, I’m really not changing anything in the status quo, but it’s the status quo that has me concerned.

Am I overreacting or is this not a big deal? Since most people in BLKN has gas this probably doesn’t come up often. It seems the gamble is no one will have their oven on high and all four burners running at the same time, but still, is it a safety risk, or just annoying if the breakers trip? The super and people I know in the building all say they’ve never had issues with fuses blowing or breakers tripping.
