Here is a mystery I'm trying to solve: My supply box is rated at 200amps, which is way more than enough for my tiny rancher. I use a ceramic space heater in the basement which is powered from an outlet near the box. When heating, the speed of the fan can vary from time to time, sometimes slowing to a crawl. I also notice that the lights also vary in brightness. The weird thing is that there are no major power consuming systems in the house that are running when this happens. What could be the cause - could it be the mains quality supplied to the house?
To add to that, it has happened with several space heaters. I've also measured the voltage coming to the heater and it does not seem to be the cause.
