Fuse panel, or a 60 amp service
I Like To Fix
A 60 amp service was adequate for a house with a radio and a refrigerator. It is not adequate for central air, an electric range and everything else. The usual sign is that things dim when the AC starts.
This is most common in homes built before about 1940. Pre-war construction — galvanized supply, cast iron drains, cloth-wrapped wiring, ungrounded circuits.
