Couple of questions from an "out of towner". grin
In the top pic, there is what looks like we would call an "inspection through box" although ours have a round body.
Over here, these sorts of things are only allowed to be installed on walls and open to sight.
If this work gets covered later on with soil or worse, concrete, does that box still comply with the NEC or local Codes?

In the 2nd pic, is this some sort of an isolator?, if so, why is it mounted so low?
I also note that the top KO has been removed, meaning that this isolator is going to be fed from somewhere else?

Is it my eyesight or is that wall on an angle or is that box and conduit run "on the piss"?
Maybe the guy built that wall as well.....
What sort of material is that?
