Hi all,
Last two weeks my UPS has been momentarily tripping. I first noticed this happening when the toaster oven was on and cycling on and off, but then it happened at night when no toaster oven was on. I also noticed that the led lights on a my dimmer when dimmed low would also become less bright. All these circuits are on their own lines. Toaster oven is on a 12/2 20 amp circuit, computer a 12/2 20 amp circuit and my leds their own 14/2 circuit. House has 200 amp service. I am seeing between 239-240 volts on the main lugs. Today I tested the outlet where the UPS connects to and turned on my toaster oven in the kitchen. Sure enough I noticed that when the toaster oven turned on, I saw the outlet spike from 118v to 128v and back down 118v once the toaster oven cycled off which doesn't make sense. I then went to the main panel and tested a few other breakers. I touched the terminal screw on the breaker and one of the grounding buses and pretty much saw the same thing. Whenever the toaster oven turned on, I would see a spike on the main terminal screw to 128v.
Does anyone have any idea what could be causing this spike? I don't think its normal for power to spike when the toaster oven turns on, if anything I should see power draw down no?
