I had a guy ask me what would cause all of his lights to dim whenever a motor would kick on. The house is around 2200 sq ft it has gas heat,water heater, and cooktop.He claime the electrician has changed the service disconnect and still no fix ,the checked the panel for loose connections the only solution was either the wire from the transformer was to small or the service entrance cable could have a nail or something in it.He said whenever the refrigerator kicks on the lights dim as the washer, and the A C any solutions?
