I have had that as a service call, along with it coming out the thermostat!!
I never did find out the exact pathway and how it happened, but I did discover that under the slab the boiler line must have ruptured, rusted the conduit for the electrical and then traveled up that, in multiple places to the stats and to a couple outlets.
This was a large commercial building with minimal maintenance done in the past. New occupants were not happy.

Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

Maybe that installer was a newbie. I've seen in some basic electricity literature where the flow of current thru a circuit was compared with the flow of water thru plumbing. I never cared for that comparison myself, but maybe this guy did ....
One time I was on the roof washing a coil and put the hose in what I thought was the plumbing vent turned out it was a conduit straight from the electrical box that was terminated ont he roof. Don't know why they did that.
am i missing something????? how do you know there is still power at the outlet. Im sure it tripped the breaker. because the wires on the outlet would have a path to ground real quick. plus it would short hot and neutral and ground all together or i could be wrong. but i still think its a pretty good picture.
