Not sure on depth but avg. frost line comes to mind. Not sure.
Tie in is done on the main lugs so unless you are on an auto start you can do everything manually like we do. Mark the circuits you want to leave engaged.
Turn off everything else including the "MAIN"............Always turn off the main.
You can get a switch gear set up that drops you off the main automatically when power drops. Not seriously spendy.
