haha! the last place i worked we had a ee put
mov networks on the contactors of every piece
of equipt in the building that used mechanical
relays.

some time later we hired some e-lec-tric-i-ans
to upgrade a fuse box, and they went all through
the building stripping off the mov networks.

when i asked what the **** they thought they were
doing they said "aw, you don't need these
capacitors any more, we put a new fuse box in."

but, they were cheap.
