Re: Generator Connections
George, how would the transfer switch otherwise be legal? Never heard of a 2-pole threeway switch. Just curious
I don't quite understand what you are asking. I think that for a permanent-temporary situation, a four gang box controlling four branch circuits using threeway switches would work.
If traveller "A" was the utility/normal home run, and traveller "B" were the feed from the generator, then the common would be the load, and the two sources would never touch. The problems are that the conductor attached to the common could be a 15 amp circuit fed from a 20 or 30 amp OCPD on the generator. Adding in a panel or whatnot would begin to negate the savings in my method.
In addition to those very real problems, we have the code stating that "audible and visual signal devices shall be provided, where practicable."
In the beginning, I was attempting to find a cheaper method than this $220 setup:
Essentially, it's six threeways (ok, with an "off" in the middle) that are breakered properly, with a visual gauge to indicate the load on the generator.
