Hello, its been a long while since ive visited.
I have a 12/3 w ground existing underground from my house to the garage. The run from the main box to the garage is 80'. I'd like to ask what the best configuration in terms of the most power to the garage, using the existing wire. As it stands I've set it up as 1 20a circuit with the 3rd wire unused. I'm hoping for 2 20a circuits, but am unsure with the single common.
Thanks in advance
