Is this doable, and if so, how? Previously in a blackout we would turn off the main breaker to separate from the pole and then backfeed our 5000w generator. We could run most anything in the house, admittedly not at the same time. Wife needed to do wash? make sure to turn off some lights, fridge, etc. wintertime, we need to make sure the boiler has power. In the summer outages that circuit would not be a concern. But I want to do this right. the manual transfer switch at home depot has 6 breakers. that means only 6 circuits can be powered? Is there a way to do what I want? To power all circuits, knowing not everything can be on at the same time?

I searched the forum and only found a one thread about this, but I need a little more detail in isolating the problem. [url]http://www.doityourself.com/forum/electrical-ac-dc/55114-conduit-used-neutral.html#post2237584[/url] In hopes that the original poster might get notified of the very late reply I posted the following to that old thread: I have this same problem, I can literally power a pigtailed light bulb from any hot wire to the conduit, or junction box in the system. The conduit reads 125V on the voltmeter from every wire (14 ga) to the conduit. I'm in Canada. The townhouse is from the late 60's. Ungrounded 2 wire (thhn) throughout the unit with mostly 1/2"emt, some larger emt from the panel to the first junction box and to the 220V outlets. There are some very, very busy (probably too busy) junction boxes with 12 or more wires nutted together. 90% of the lights and outlets on 2 15A circuits. The previous owner has made some additions with BX and romex, one gfci breaker that used to be for a jetted tub, but I've deleted it. What's the first step in isolating and locating the short? Thanks for any help!
