Video advertisement discussing the telephone equipment that was needed
before the buildings could work....

- in the website's discussion, they comment that "None of AT&T's
employees were hurt in the attacks." That's kind of true, but some
Verizon personnel were killed.

If you're up to doing a bit of the wiring yourself,
a standard automotive fusebox could work. The one
in my car is about 5 inches by 5 inches by a foot long,
and has slots for a dozen or so large fuses (not sure
of the general name, but they're about an inch long
with two big prongs sticking out) ranging from 5 to
40 or 50 amps. (This box also has a dozen other physically
smaller fuse slots).

You'd have to wire in a meter yourself...
