I just installed this on my electric panel. Took about 30 minutes. It allows me to plug my 4500 watt generator directly to my gas furnace. I was using a propane ceramic heater to keep us all alive during a power outage in the winter but this will keep the whole-house system running normally. Plus, it looks really cool, like something out of an Austin Powers movie. Accepts a regular three prong female end of an extension cord. Click image for link.
