Re: How long does a PWRDWNSYS restart(*no) actually take?

An enterprise class UPS would simply drop to bypass.

But what if the load on the wall outlet which will suddenly double when the UPS dies is now enough to simply trip the circuit? Oops.

Similarly if the wall circuit is tripped or disconnected the load on the UPS doubles. If that wasn't allowed for.... Oops!

Curious to the logic of plugging one into the wall and one into the UPS?

We installed a Natural Gas powered Generator 4 years ago.
the first year I tried to tweek a UPS monitor program...
We kept finding "what if" conditions, but found that from a UPS -

perspective, they both were very reliable.
So I no longer have a monitor program...
Monthly Generator tests, Quarterly UPS testing/Diags.
