FYI,
I recently bought a 220v air compressor and was looking today at wiring it
up. My house has a 125 amp sub-panel with some spare breaker slots, so
should be no problem, right ?
Well, turns out that sub-panel and it's breakers were made by Federal
Pacific. I'd never heard of them, but when I called a contractor friend, he
immediately said "Aren't those the ones that catch fire ?" !
Turns out he's right. Apparently "back when", Federal Pacific falsified
their data to receive UL approval, and their circuit breakers (and panel)
are simply a bad design that should never have been sold. A high percentage
of the breakers can fail to open under various fault conditions; and even
jam permanently closed so they will not open under any fault conditions !
It's a long, strange story; still being played out in the courts. Lots and
lots of details at

You might want to check what kind of circuit breakers your home has ...
I'm off to look at new sub-panels.
