Out of curiosity, what is the distance between the top of the standing platform (incl. thickness of deck) to centre of axle on the GTA/WTF? It might just be parallax in photos but, it seems as if its either inline with the centre of axle or only slightly below the centre of axle with how thick the deck is.
I’m also curious as to what the same specification is on the v5 chassis in comparison, and the same with the spine. I assume the spine is the tallest of the three with its thicker wooden deck and different chassis configuration, but also curious as to how much.
I don’t necessarily have a strong opinion on this specific case, but that is a pretty big misrepresentation of house wiring. Both every ground and neutral in a house run back to the panel through wiring. Tying all your grounds to rebar near the outlet or something like that absolutely wouldn’t pass code anywhere I’m aware of. Also, with house wiring, in an ideal case, you shouldn’t even need the grounds, and they shouldn’t be a part of the circuit. Trying to use the rebar as a neutral would be even worse than trying to use it as the ground.
That said, it is certainly used on cars.
Edit: Also, with appliances specifically, running neutral through anything other than a wire wouldn’t pass any certifications. Ground is different, but again isn’t part of the circuit in that case.
