Multiple Transformers on a block

In theory, your idea should work as long as you are absolutely certain that only one of the power packs is on at any one time. The biggest problem encountered would be if they should inadvertently both be on but set to opposite polarity.

Did not think this thru the whole way yet…What about using 2 three way light switches? The same ones you use to operate a single light from 2 locations. Have a switch and receptacle at each power pack. If pack A is enegized this automatically kills pack B and vise versa.

OK, I’m not following what you’re trying to say here. I’ve wired this type switch pair and the two switches will apply or remove power to a single load, be it a light or a power pack. They’re basically a SPDT switch with a 3 conductor wire running between them. How you’d wire them to turn on one while turning off the other is a mystery.

I made that post using my limited knowledge of basic electrical design thinking that when the switch that powers pack A is on, pack B is automatically turned off. Flip on pack B’s switch and pack A loses power. Perhaps the 2 switch/one light scenario won’t work but there should be a relatively simple solution to this.

No need to appologize, I was just hoping to add another tidbit of info to my wiring knowldege. I once had to show an electrician how to wire a duplex outlet so only one of the sockets were controlled by the wall switch.

Now that I can accomplish. Its amazing what those 2 little strips of brass alloy can do when removed. The most difficult part that is pulling your wire in such a way as to not be needing to go and buy a 12’ pc of 12/3 romex or doubling up on the 12/2.

It would be nice for future reference to see a diagram of the OP&
