Stephen dug a trench with a "trencher" (practical if uninspired name.) It's like an enormous chainsaw. Then we put thick electrical cable in PVC pipe, fastened the sections of pipe together, and dropped it in the trench. Stephen attached an electrical box at the pole, and another in the shop, and attached the cable to it at both ends - we will have buried lines. Then we started putting in outlet boxes upstairs. We have not gotten them all in, but we got most of them. They don't have any actual outlets, switches or lights in them - they are being put in primarily to allow the installation of the insulation. The insulation covers up the wiring, so the electrical has to be done first.
You can see in the photo the electrical cable in pipe as it comes into the house at the left.
