I'm pulling 240V into the garage, 2 30A breakers (THHN #10 1 red, 1 black, 1 neutral, 1 G), plus two 120V 20A circuits, one dedicated to the refrigerator, one for another appliance (old house, mostly non-grounded circuits originally). So that's 4 #10 and 4 #12 (since I'll share the ground to the junction box in the attic where the circuits split, and run romex the rest of the way). I need 3/4" conduit to hold these wires, and a way to get the wires into the breaker box, which is recessed into the wall of the house with wood siding. So my plan is to put an all weather box on the outside, below the breaker box, and run the cable from the knockout in the bottom of the breaker box to the all weather box mounted on the outside. I'll run EMT from the all weather box into the attic.
