I want to save a little on wire if possible on two circuits and run one 12-3 instead of 2 12-2 inside the house, through the wall and to an outside outlet. I plan on putting the 2 GFCI outlets in the basement to protect them better. My question is can I share the netural wire AFTER it leaves the GFCI?
The other question is do I even want to share the netural up to the GFCI or should each run be dedicated. This will be 20 amps and I expect to have them near capacity.
