Ok ,guys. Now something just came up . I know we are up to 51 posts
for this thread already, and I was not sure whether to continue this
one, or start a new one, but anyway:

My friend had an idea if he had gotten a generator one day, he can
utilize the A/C disconnect panel outside to backfeed into the main
panel. Of course he would shut off the main breaker and pull the A/C
disconnect when he did this.






Hay bailing sounds great and of course he will never forget, be sick,
not there and someone else needs to do it or whatever.


What you described is simply hay bailing instead of using conventional
common methods.



I can put an outdoor twistlock outlet next to the A/C disconnect
panel, and put a short nipple between them an connect the wiring.

But I cannot do this with the existing 10 guage wire since it is the
old 10/2 stuff with a small ground on it. I would need to run an 8/3
with gnd ( 2 phases plus neutral).

I know this is not the right way to backfeed a panel, but regardless,
does it make sense now to run the 8/3 ?
