Friday
Hannah and I pulled in at 2:30 with a rented trencher in tow. I picked this up at Kitz and Pfeil in Berlin on the way up. This weekend is dedicated to running new power lines to the keep and pole barn straight from the new service panel we installed last fall. After opening up the keep and getting my clothes and other supplies put away, I unloaded the trencher from its trailer. This is the same one I rented back in 2011 when I made the first buried electrical runs. While that project was a significant improvement from previous methods of getting power to the keep and pole barn—stringing extension cords through the trees—the limitations were starting to show.
This is my trencher. There are many others like it, but this one is mine (for the next 24 hours).
When I first did this seven years ago, I used 10-gauge, 2-conductor direct burial copper cable…mostly. Power was supplied from two 20-amp breakers in the big trailer and run to an outdoor service box using 12-gauge romex. The thicker 10-gauge wire was only run underground to each building where it was spliced to 12-gauge romex in conduits. I also didn’t have subpanels at either building. In the pole barn, I just spliced the incoming connection with wire nuts. In the keep, I gutted the contents of the old fuse box and spliced everything together from the feed, and this was after a spliced stop at the water pump outside. In retrospect, this was terribly kludgy. When you consider the system it was replacing, however, it was revolutionary. Still, the time had come to revisit this project and do it right this time.
