Our 1,600 sq ft 1952 ranch house had 40 amp service. What it was built, it was TWICE the size of the average house being built in 1952.
As you might imagine, we were blowing breakers all the time. We finally remodeled the kitchen ten years ago and upgraded the electrical panel and drop from the pole to 300 amps.
We had a 60A service and a fuse box for decades.
I got very good at knowing what to plug in where and when.
When we upgraded we went straight to a 200A service.
What a difference.
