A few weeks before Christmas I kept getting dimming lights in my craft room. I knew this meant that I had way too much on my "surge protector" but I was trying to finish my Christmas quilting projects so I forged ahead. There went ALL the circuits in my craft room--ceiling lights, wall circuits, EVERYTHING! Though connected to a surge protector, I had too much on it (and my house is only 17 years old)--iron (big electric pull), sewing machine, floor lamp, ceiling light, and space heater (because my downstairs gets cold). My electrician just looked at me with a "You knew better look!" Now I'm more cautious and I'm going to ask my electrician to pick out a surge protector for me.
