We live in the country and the power goes out

often. So I bought a 5000 watt generator,

circuits.
I'm told it is not wise to operator sensitivre
electronics such as big TV sets and computers
on
generator power. In fact I'm pretty sure thats
hiow I
blew a DVD/VHS unit last year. And the digital
read out
on the refrigerator has lost part of its
alphanumerics.
My question...what is and is not safe to run?.
Will a surge protector ahead of the device in
question
prevent a problem?.
I actually ran a small TV without a problem but
not for
very long. Would appreciate a reply from some
electrical
guru.

The problem is more a matter unstable &
unfiltered than
surges I don't think a surge protector would
help.
A really good UPS might though. We lived on our
generator
for 2 weeks following a storm a few years ago, I
finally
freaked after a week & booted a computer to make
sure the
internet hadn't forgotten me. I was probably
lucky, it
didn't seem to do any harm, but it was up less
than an
hour.
That's bass ackwards, but in my case I've run my
computer on the genset via my UPS with no problem.
I know it's not advised, however, to run them
directly. I've looked at the output of mine with a
scope and it's actually a very good sinusoidal
output with no spikes/surges on it. House-born
surges however tended to be higher than normal,
probably because of the last of the grid xfmr and
split phase connection. Not sure I'd do it
without a UPS though without knowing a lot more
about the output specs than they normally give.
