I have two outlets in my apartment that do not power down with any breakers.

I have to pull my main breaker for those two outlets to be without power.

And I have the full schematics for the wiring in my place.

And it's not that they show these outlets should be wired to a specific plug either.

The schematics don't show those two outlets at all :|

Even weirder, I have a digital power meter that autoreports my usage to the power company and has a reporting port that I feed into my Grafana installation that reports down to the milisecond.

When I power things through one of these outlets, it shows fuck all increase in power consumption on the meter.

So, one of the two outlets seems to be drawing power from either another apartment OR the buildings main grid that runs the utilities and halway lighting etc.
