Is that correct? If it is you can fix this setup by using a shunt trip main breaker with a pair of auxiliary contacts. If you actually interested in anything other than trying to validate your existing setup let me know. -- Tom Horne

If it is there is a very practical way to wire the interlock that has no likelihood of cross connecting the utility and generator power. If you are interested in anything other than validating or arguing about your present set up let us know. -- Tom Horne

He is heavily medicated and probably not receptive to logic or what you would consider common sense. Psychosis is a break from reality, like a waking dream state, with its own logic and rules. While Jon is intelligent, he works by different perceptions than you or me. I would not encourage his experiments with mains power. He's dangerous enough with alarm clocks. http://www.amazon.com/gp/pdp/profile/A1885J18PY8I7S http://www.amazon.com/Electric-Alarm-Clock-Selectable-Display/product-reviews/B000DZCRHQ?pageNumber=3 "I took this clock apart and wired it to ring a 95 decimal fire bell when the alarm goes off. I have to admit I am impressed that the clock still works even after all my wiring mistakes. Now I have myself a good clock with a lowd alarm to wake me up." Would you want someone taking this amount of psychoactive substances near electricity? http://mypeoplepc.com/members/jon8338/mypersonalsite/id5.html Or someone that needs a "95 decimal fire bell" to wake up even with 30 cups of coffee a day?

I AM NO PHYSICIAN BUT HE SOUNDS LIKE THE TYPE OF PERSON THAT A DOSE OR TWO OF LISERGIC ACID WOULD SET HIS MENTAL STATE RIGHT JUST LEAVE HIM ALONE ON HIS LITTLE PRIVATE TRIP THROUGH LA LA LAND IN A ROOM FULL OF ART AND UPDATED ELECTRONIC GADGETRY [;)] IF HE HITS THE RIGHT TONES ON HIS AUDIO SYSTEM HE MAY LEARN THE DIFFERENCE BETWEEN DECIMALS AND DECIBALS TWAHAHAHA TWEHEHEHEHEHEHEHE IAP
