FRom news reports, Queens seems to be a combination of poor engineering (setting the fuses high enough to damage the wiring on ultra-hot days) and poor load management.

Apparently they have over two dozen parallel feeders on the medium voltage circuit.  A couple went out and instead of load shedding immediately, they let in run.  Enough to damage the wirubg on teh other circuits.  I would be willing to bet that they are WAY behind in their tighten downs and other routine maintanence.  (Tighten downs eliminate loose, high resistance connections).

Maintenance? LOL. They haven't maintained anything in decades. NYC politics says "keep the rates down at all costs". Always has. Just like on the subway. And it also says, "hire and retain from the bottom of the pool" as needed to keep the employee census numbers at the politically-correct values. Anyway, the money "saved" will now be spent many times over to replace spoiled groceries, lost business activity, and, perhaps, damaged appliances and equipment.

And our social-science academics, in their disconnection from reality, still keep wondering why a lot of Americans abhor  big cities!
