I have close to 200 databooks in paper format, and thousands of
datasheets or databooks in PDF files here at home.

I found design errors in many older products at Microdyne, and
came
close to being fired over it, several times because the older
engineers
were furious that a tech had the nerve to point out a ten yer old
mistake.

There is currently a thread on a Facebook group where someone
used
two short SFE 32 VDC automotive fuses in series to replace a 3AG/AGC
250
volt fuse. The idiots think that it's cool, and or funny. those 32
volt
fuses will not open reliably at 250 volts. According to the long
standing data, the first to open will create a ball of plasma, and
keep
conducting. The heat will destroy the fuseholder, and the fire can
spread into the wiring, and on to the surroundings.


Wow. I'll bet that would be fun to watch.

If _my_ job wasn't directly involved, that is.

Hmmm....what would make a good 50A 240V current limiter?
