Checked a job that the voltage on one circuit will run about 117v, then will drop down to 112-113v for a couple seconds, the current jumps up from about 12a to 17-18amps at the same time not long enough to trip the (battery back-up, (kicking on I believe), 119-121v on other circuits at panel. They have a Server with a battery back-up and it causes the the bat back-up to kick on.
I'm thinking of just adding a 20a separate circuit. But it still seems weird that the voltage would drop that much. I checked connections everywhere for possible bad connection, causing resistence, not that.
I can see overloading a circuit and the amps jump up, but the voltage dropping that much, (unless there was a bad conn or something), plus the breaker isn't tripping. possible bad breaker too?
Anyway, the separate circuit should solve the problem. Any thoughts?
