No Fix
It’s official. The splice in the power wire to the barn was not the point of failure. Where does that leave things? Right where I didn’t want them. The electricians were unable to tell me where the break in the buried wire might be occurring.
For the time being, I have chosen to continue to rely on one “hot” line providing 120VAC to all the circuits in the barn. That is the way we have been operating since the problem initially occurred in January, and it has proved to be sufficient.
Since we haven’t been able to come up with an explanation for the failure of the one line, I’m concerned about the potential risk of the other line suffering the same fate, which would leave us with no power at all in the barn. The guys said they see this kind of thing with a surprising regularity.
Apparently, there is a lot more going on underground than I realized. The causes they’ve seen include tree roots, burrowing critters, and rocks pushing their way into the wires.
My plan, at this point, is to live with the risk. If the remaining power line suddenly fails, we will run an above-ground extension cord until we can get scheduled to have new wires bored beneath the driveway. I asked for a quote for the expense of this work and learned that although it wouldn’t be cheap, it would be less than I anticipated.
We will be saving up for that eventuality. Hopefully, we’ll have years to tuck away the funds.

More Digging
What’d you do yesterday? I dug through dry, packed gravel that was as hard as concrete to uncover even more of the AC power wires to the barn. With Cyndie’s participation, we worked together from two ends and met in the middle.
The owner of the Electric/Plumbing company we use for service stopped by in the morning to assess the situation. He was concerned there could be an additional splice and convinced me to dig up the rest of the lines all the way to the barn.
That was easy for him to say and a heck of a lot of work for us to do. At least we now know there are no other splices, at least not in that direction. I have very high confidence the patchwork that was done over ten years ago did not involve any more than the bare minimum repair to solve (and bury) the problem they had created.
What still remains unanswered for now is whether or not the splice is where power is actually being lost. I have notified the company that the cables are exposed all the way to the barn, allowing them to schedule an electrician to (hopefully) verify the splice is the problem and then redo all three splices with a much higher-quality up-to-date process.
I’m looking forward to that work being done so we can put all that class 5 gravel and thick clay soil back where it came from.
I don’t know what today’s projects at Wintervale will be for us, but I’m going to make every effort to avoid anything that involves digging.

Found Them
Before we left for Iceland, I was lamenting my inability to locate the buried AC power wires running from the shop to the barn. I gave it a couple of new somewhat half-hearted tries since we’ve been home, digging as time allowed without success.
As a reminder, this is the photo I’ve been using for reference from 2013 when the wires were accidentally cut by a skid steer making a driveable roadway behind the barn.
I must admit, I assumed I was searching for a single bundle of the three large wires but reality proved different.
Trenching my way deeper and deeper along the slope of the small hill finally revealed the yellow line on the cable for the ground wire.
Despite my confusion about how far to one side or the other I needed to be searching, the find finally came at the most likely spot.
With the wires uncovered, I’m a little surprised about the angled direction they are routed at this spot. Now I have plenty of methodical hand digging to do to reach the location of the patch that was made when they were cut. That is the most likely spot that would cause the loss of continuity in one of the power lines.
I’ll be calling the electricians tomorrow to schedule their services and find out how soon I need to finish the rest of the digging. At least I know where to work and won’t be wasting any time on fruitless searching.
