re: Dimming lights when I run power tools

Current in-rush is a bitch ain't it? There isn't much you can do about it, power tools consume far more power than household lights and the current draw is going to pull down the voltage a bit and dim the lights a little. You can see if the utility will run a heavier line to your house (for some reason my house has much thicker cables than any of my neighbors) or you can run a UPS for things like your cable box.
