Testing said combination of UPS and generators? What if it was

facility like that and people actually *pay* for it.


Sad that the little Telcove DC here in Lancaster, PA, that Level3  
bought a few months ago, has weekly full-on generator tests where  
100% of the load is transferred to the generator, while apparently  
large DCs that are charging premium rates, do not.

        And I could tell you about large DC's that are charging premium
rates, had (admittedly) quarterly generator tests that ended up failing
and causing down time MULTIPLE TIMES too. Meanwhile the generator at my
parents house I had installed has weekly tests and runs fine, but I'm
waiting for that unbelievably cold unbelievably harsh winters day where
the power goes out and the generator fails... Because its a machine. It
has wear, it breaks. I don't know that I'd be comfortable with a full
load every time. Rather it be load banks....
