Yup, that's what I meant. Protection and backup used interchangeably, even though it wasn't really the right words.
Protection is full time, as it should be, back up power is as long as it lasts. The only power outage I was able to see it in action was a brief 20 second outage, worked fine, no idea past that how much time I have, I'm hoping for 10-20 minutes. Glen
