WRONG!

One of the bigger problems with this design is the type of stab
into the bus. It often results in high-resistance contact and
resulting overheating.
In minor cases, that can mean inconvenience when lights on one
circuit flicker. In severe cases, it can end up with a melt-down
of the panel.
You have not truly lived until you've attempted to pry out an FPE
breaker and had it crumble into dust in your hand....
I used to think that testing of the breakers to ensure that they
tripped was adequate assurance of an FPE panel suitability.
No more.

I still like having fuses for mains. I have them on my farm, and was
going to eventually replace them until I ran into a burned up Square-D
panel in a building I was demolishing. When I acquired that building,
one of the first things I did was to get that panel before someone had
a chance to steal it. I was a 100A panel, completely filled,
including a few tandem breakers, and one 50A dual breaker to a sub
feed, which was an old fuse box with at least a dozen fuses. I
brought it home and what I found shocked me. The 100A main was siezed
in the ON position, and I finally busted off the handle trying to
force it to shut off. The 50A subfeed breaker worked, except it was
welded to the bus bar and so badly charred where it connects to the
bar that is fell apart. The two single breakers above and below that
50A were charred from being in the same location. The other single
breakers, and one 30A dual were all OK, That box was so overloaded, I
am surprised there was not a fire. All I saved were those good
singles and that one 30A dual. Everything else went in the trash.
There was even charring around some of the neutral screws.
I like single breakers, but for a main, I still think fuses are the
safest.
