At this point in the thread, an amusing anecdote is needed...
About 25yrs ago, fresh out of uni, some-how 'Architect of Record'.. in a location on N Borneo. Well: I was on site the day the substation was energised, on a large development of shophouses, and - as was usu then/there/ all the sewage went into digester tanks, relying on oxygen circ, before anerobic digestion, and all that follows; a standalone system. Pretty darn efficient tbh when done well.
These digesters relied on, up -to c. 100KW of 'blowers' ( helical air pumps /exactly/ like a supercharger after the GMC 6/71 and sim beloved of Drag racing fans. but, very large) As such - hooked to very-large 3-phase motors. Yet - obvs, since the thing took >1yr to build .. those tanks were, erm, already-filled by the site workers, long-before energisation.
And
-when energisation happened - there was the most almighty, utterly- Rong, glorping/suck noise - and I ran for it, as the foreman shouted .. very rude words at the electrician. Yeah: wired with phase reversal. (NB to all others - you only have to swap any 2 wires, out of 3 on a 3-phase system - it is , easily done.)
Literal case of just-avoiding the S%it hitting the fan; mercifully, blower-input at top of tanks weren't ever really going to draw-much; and the input filters caught it %}
