The housing stock behind Cook County's wiring
What the numbers mean at the panel, for a county inside this metro: 2,471,836 of the footprint's homes predate 1980, built when panels were smaller and circuits fewer; 645,165 arrived since 2000 with modern service sizes. Cook County contains its own proportion of both — and a homeowner here can place their street in the ledger by its build decade alone, which is also how the electricians serving the county triage what they are likely to find. Its neighbours - Lake County, DuPage County and Lake County - hold the same bands in different proportions, which is why their pages read differently from this one.
The climate Cook County wiring works under
From CHICAGO MIDWAY AP, IL US's record, the working conditions over Cook County: 5,753 heating degree days against 1,111 cooling degree days, 19.8 days a year reaching 90 or more, 106.3 nights at freezing or below, 34.42 inches of precipitation. Those figures cross the county without respecting its borders, and they load every home in it the same way at the same hours — which is why electrical failures here, as across the metro, arrive in seasonal bunches rather than at random. The county's 945 square miles take that record whole; there is no milder version of it inside the county line.
