Sizing Portable Generator for Back-up Power at Wells
Sizing Portable Generator for Back-up Power at Wells
(OP)
I am in need of information on how to spec a portable generator for a potable water well. I have collected the disconnect information, i.e. 3-phase, 400 amps, 600 V. However, there are two disconnects at the well house. One was on the outside of the building and is 400 amps, 600 V, and the disconnect on the inside of the building is 30 amps, 600 V.
Any information on where to go from here is greatly appreciated.
Thanks,

Next you need to find out what the actual loads are, i.e., what loads the generator will be running, and what loads it will be required to start. You will need to list actual rated/expected voltages and currents for each load. For motors, several currents are of interest, not just one.
Loads might include:
Pump motor
Battery charger for generator's starting batteries.
Area lighting.
Service outlets and inside lighting for generator.
Beacon to make status visible at a distance.
Systems for logging, remote monitoring, control.
Transfer pump for filling generator day tank.
Fire suppression/ alarm system.
CCTV or other intrusion detection/ recording system.
