10-4, if you (or anyone else) needs something like this in the future you want to check with your electric provider as IOUs, most co-ops & some municipals have a 3 phase data recorder they'll loan out/set-up to help diagnose issues. The company I work for serves 92 municipals across NC, SC & VA (Clayton & Wilson are 2 of our members along with the other 3 I mentioned) and we have 2 to assist those that don't own one. Last time I used ours was in Edenton to diagnose why an elevator kept tripping the breaker and the elevator company blamed the incoming power. Left the recorder on the main feed for one week, on the elevator circuit the next & a nearby coffee shop the next. Elevator company finally sent a tech out and fixed their problem after seeing the graphs.
