First repairman from the utility showed up about 10AM, only 2 1/2 hours after I phoned in the outage. He'd already looked at the pole and transformer and found two blown fuses. Said he couldn't understand what would cause that, and I came clean with the digging and the bare spots on the wire. He starts to climb down in the trench and I move to turn off and unplug the generator, then clarify for him what that line does an how I've been backfeeding the subpanel in the garage with the generator output. Came clean about not using a transfer switch, got a little lecture, which led me to confess my sin and plead for mercy, being as when the Safety Shutoffs started I couldn't get an electrician to install one, and was within a couple weeks of replacing it with a whole new inverter based solar system. That settled him right down; I think he appreciated that I leveled with him and wasn't trying to hide anything. That kind of behavior gets people killed. We had a pleasant time from there. He trimmed back the cracked conduit, showing me a cool trick for cutting it with string, then he wrapped the torn insulation with electrical tape to get me by. Another crew is supposed to show up this afternoon with a new transformer, and before he left I had the name of a metal building manufacturer not far from here where he got his 40'x60' barn. Really nice guy, as have been all the PG&E people I've worked with. Now maybe with a new board and CEO the company can get its head out of the dark place it's been and start taking care of business.
My take away is to kill the main breaker so the buried line isn't hot while I'm digging. That way even if I crack the conduit and scrape a wire again, I can make the same repair and still be able to have grid power. That transformer has been making noise since I bought this place, so that'll hopefully end up better, too. I was told there would be no charge, but then again the next crew may have a different idea about that...
In the first hour after resuming the dig, more than half what came out of the trench was large ottoman sized rocks. and now the top of the trench is 3' over my head, enough that I don't really feel comfortable going into it anymore.:shocked:
