Was shoveling snow from the driveway yesterday afternoon, facing my shop with the shiny class A chimney right in view, and I heard a massive explosion and saw an intense flash of light, looked like a rocket launch right out of the chimney. Thought - that never happened before. Then I turned a little while still shoveling, and another massive explosion with another intense flash of light. This time I wondered whether the chimney would stay on the roof, but also I caught a glimpse of the overhead main power line almost right above me. A branch had fallen from a tree and shorted out the 2400 volt feeder line, and I was standing right under it. Power went out instantly, and then I thought, overheat? - the Tarm was in high burn, I had just added a load of wood. Checked it out immediately, and the power loss of course had cut off the draft fan and circ and opened the overheat dump loop. No overheat, everything was OK. I quickly started my 2000W inverter generator and restarted the Tarm. Within 2 hours the power company was out to clear the branch from the line and restore power. Don't ask why I was shoveling snow on April 11 - just dealing with one more spring snowstorm. We remain in full snow cover on the ground and on the lake, a foot or more, and ice on the lake must still be a couple of feet thick, with more snow and temps in the 20 - 30's in the forecast for the next 5 days. Very happy that plenty of wood remains on hand to heat the house and shop.
