Amp for a 4 family brownstone
We are currently renovating two apartments in a brownstone. In both apartments we plan on renovating the kitchen (including modern appliances such as dishwasher, gas range, new refrigerator) and bath as a result our contractor suggested we upgrade from the existing 40amps to 60amp or 100 amps.

We are currently renovating two apartments in a brownstone. In both apartments we plan on renovating the kitchen (including modern appliances such as dishwasher, gas range, new refrigerator) and bath as a result our contractor suggested we upgrade from the existing 40amps to 60amp or 100 amps. Is this necessary to perform increase the amps per apartment and if so how much should we expect to pay? Thanks.
40A is very low, 100A should be fine. If you don’t have w/d in the apt even 60A may be ok. Here’s a simple calculation:
2 window a/cs: 2kw
d/w 1.5kw
refrig .5kw
major kitchen appliances (2) 3kw
lights with 2 bed 1-2kw
misc 2kw (hair dryer, computer)
So that’s 10-11kw /220 = 50A if everything is on at once.
Now, if you’re planning to have a dual-fuel range (electric oven), major computer server, or four dozen recessed non-cfl lights…
