3, is it normal for buildings to have 3-phase in split into different single-phase sections? That feels like you could get some iffy stuff from wildly different loads on the different phases.
First off, instead of using bullets and then manually enumerating then, try putting "1. " at the the start of every item in the list. Don’t increment the “1”.
Around me the only homes without 3phases are older small apartments. Most houses have a 35A 3phase supply, although 63A may become the norm on account of EVs. It’s quite normal to have a 3 phased fuse where each phase is used for something different. Say a fuse box is used for lighting and outlets, but L1 is ground floor, L2 is upstairs and L3 is outdoors.
BTW if you ever move into a house where someone has put outdoors on the same rcd as the rest of the house, then do yourself a favor and get a separate combo rcd/fuse for outdoors. When the rcd trips, it’s always the outdoor usage, and it sucks when all the lights go out, because a gasket died in an outdoor lamp.
we were recording the magnetic fields generated by a high-energy short circuit. we hung a mouse trap from one of the lines, with a lead going to one of the others, so that they fused together when it sprung.
it is normal here, yes. larger appliances get three phases, and single-phase outlets are split between them as evenly as possible.

Sounds like an industrial setting, they typically get three phases. Probably also explains the desire.
