hey guys im new to this web page so go easy on me. Im also kind of new to the electrical field so i would apprecite your knowledge. I have a question? Is it normal for a home (built in the 50's) to have dimming lights when appliances get turned on. For example the washer and dryer will cause the light to dim or when the refrigerator kicks on.Is this a big problem? What causes this and can it be fixed?
