I have 5 elevators in one building, 4 units are identical with motor 15kW, and one unit is 11kW. The power supply is 3-phase, 380VAC, 60Hz. I want to know how to calculate the size or the capacity of the standby generator if:-
Case 1: All 5 units elevator should be operative by standby generator when power outages
Case 2: Only one elevator to be operative during power outage driven by standby generator.

I have 8 switches but only 5 inputs to my microcontroler, so the idea was to encode( switch 1 is 0001, switch 2 is 0010......ect ). I need to keep power consumption down so I was told not to use a 74148 encoder but to use a 4067 line mux, but this doesn't help me. Is there another solution, maybe a low power encoder?

How do I work this out? How did you get to your answer?
