What Marc and Douglas have said. Do not use your existing circuits unless you have a proper transfer switch or switches installed. The risk of someone, maybe not you, flipping a breaker and shocking a linesman up on a pole is just too great. The cheapest way is to simply run a couple of good quality extension cords from the generator to the appliances, and just plug in what you need. Build a weather-proof gasket so you can feed the cords in from outside. Cheaper than that? Go mooch off a buddy til the power comes back on. [] I have seen the notes, "do this, then do that" where people have rigged up their own generator hookup. Now the house was being sold to a possible ignoramus with the potential to kill somebody. It may be illegal. It is certainly not permitted anywhere in our two countries. Here's a note, how to run a 'genator'. If the duct tape comes loose, they would write the buyer new note, maybe? Which one is the main? And what if power goes off in the summer, not the winter? Click to Enlarge 38.91 KB
