We think there was a pinhole leak in a water line in the lazerette which sprayed the electrical and caused a little sparking/meltdown. What we can't explain is why the breaker never tripped. Bad, bad, bad.
Nonetheless, I'm still thankful. Thankful that Frank was working from home and returned from running errands before it got any worse (he had to isolate the power since the breaker didn't do the job). Thankful that we were able to still sleep in a heated home last night (diesel heat wasn't impacted) and that our home is more or less whole still (just a little singed). Thankful that nothing was hurt that a credit card can't fix.
We (mostly Frank) will make some adjustments to the plumbing as we put it all back together, but life goes on!
