        To be safe and legal, the switch needs to be able to be an either/or type - in that if thrown in one direction it is channeling power from the main supply and in the other it is channeling power from the generator. It must be set up so there can be no backfeed.

        So you need to buy the switch. I can't imagine any way to make one that will be better and/or cheaper.

        If the structure of the house makes it fairly easy (eg. on a crawl space) I would think about running an independent line not hooked in to the house electrical line. When I had a week end place I had planned to run a line with an outlet for the refrigerator, the living room, and the bedroom. But decided to sell it and build a year-round home.

        I would think code would not only require a break-before-make SPDT switch, but the airgap between contact points would be either quenching or impossible to arc 600 volts ( usual insulation standard for power wiring .) say, contact point for source A on the left side, and for B on the right side. that kind of isolation.

        the moosey manual/automatic transfer switches for commercial power busses come to mind. but they sure don't come to Papa at thousands of bucks each.


        sig: if this is a new economy, how come they still want my old-fashioned money?

        Twist-Locs? how illegal would it be to put Twist-Loc receptacles on the lines (or on a subpanel to the lines you want to back up) and transfer the SO type cable between the main panel's receptacle and the one to the generator? anybody? sparkies?

        Frodo, thanks for the link.
        Watched a video or two on this product. While you could make one from idle parts on the work bench exactly what specs are you building this device to?
        Question number two relates to UL listing of this product. I would think the manufacturer of this product submitted it for safety testing. As installing this device if not tested is downright dangerous and raises insurance issues. As in fire insurance coverage for installing untested electrical products. By making this device in your laboratory raises these issues.
        That is the first two questions that come to mind. Could YOU assemble one on your own? Certainly so. The $300.00 price tag you mention seems like about twice as much as I would ever think about spending for this device, as devices are presently on the market that provide more circuitry options are not much further out of reach.

        All in all a very interesting product. Big Grin
        E-Bay maybe, always worth a peak....

        Agree. As in my other post I'm thinking this device would not pass an UL inspection process if it allows backfeeding that is incredibly dangerous to linemen working to restore power during outages.
        Build one on your work bench, exactly how do you meet this demand?

        I may visit this guys website today. The problem with product that most see is its limited use. As Frodo posted needing heat, icebox, a light or two and entertainment rules out this product.
        While this may well be a great product, $300.00 is way too pricie for my needs.
        Snow and cold here today, heck it is January. To us its just another normal winter day, to CNN its the end of civilization as we know it.... Wink
