Lights pulsing dim every 30 -45 min or so
New house just built, it seems the lights, flicker dim for a moment about 30 45 min apart, I can't seem to associate with large appliance activation, it happens when all a/c is off. Seems to happen on all circuits, the lighting is run through a sub panel feed off a main panel out side, also having bulbs burn out pretty often. Is there any thing to l ook for, check, test to narrow down the causes, How would I check if there is an issue from the feed at there pole. The ups's on the computer don't trigger when this occurs.
