I have one of those 'endless' type swimming pools that uses a 220V
3-phase elevator motor to power the propulsion system. The single phase
220 that comes into the house is converted to 3-phase for the motor
using a Hitachi L300P inverter. Could not this, or a similar device, be
used to provide 3-phase for computer equipment? I have not posed this
question before, simply because I have not been trying to install
computer equipment that would require this type of power, but this
discussion made me curious.
