When I watched the video I first thought WTF, everything's outside, the mains distribution, gas, the boiler and the inventer. Over here (nearly) all homes got a cellar, so everything's inside. And the few homes whithout a cellar got a dedicated utility room for all that stuff.
yeah i found that odd too, i mean the fuixebox is publicly accesible!!!, that's a big "NO NO"!!.
not even a transparent window so that the utility guys can meter without opening it!.
over here the meter lies on the downpost from the overhead lines(or underground downtown) with a transparent plexiglas window(it's not a protruding wall-installed box but an embedded one), the door has a special secure lock that only utility guys have a key to access.
That box is han
On another small box lies YOUR side of the grid per-se where you have to put two big screw-in ceramic fuses(they look from around 1920ish) in what iirc is a lot like an edison screw, the fuse is actually a strand of wire(the fuse itself has two screws to replace the "fusing element"), if it blows you essentiually eyeball it.
after that it's all inside the house, if the fusebox where to be accesible like that it would take days for someone to shut-it off it in the middle of the night, break in and rob/kill/rape everyone for hours.
our water/heater tank is also inside the house, no dedicated room per-se(it's a small room without a door) and they design is vastly different, Dave's look like some industrial HVAC unit.
Also, i don't remember seeing a differential breaker(or at least not in the configuration i'm used to, which is that king of fat/boxy front ones), that strickes me as odd
