200 amp service in my house... #10 wire going to the garage 120 foot away... for 220 service through a 30 amp 220 braker... I'd lite to back feed to the house with a 6250 generator... generator puts out 220 with 20 amps on each side... with #12 wire... can I use the 12 wire... run it 20 feet to my sub panel that's in the garage... my sub has is own ground rod... ground and nutrual are seprate.. when the main 200 amp braker is off and I'm back feeding... any danger with the back feed through the nutual going out to the field?
Thank you my friend... richard
