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