However this places all home electrical wiring in the low voltage class or lower.
If i have a question that asks how to wire up a motor that has available leads of 208 volt 3 phase.
Every motor ive ever seen has labeled the higher numerical figure as high voltage on the connection diagram.
As in if you have a 230460v motor the high voltage connection is for 460v incoming service.
The iec ratings for voltage list high voltage devices and lines as anything over 1000 volts for ac circuits and 1500 volts for dc circuits while low voltage circuits are between 50 and 1000 vac or 120 1500 vdc.

Sometimes you apparently need to rewire a 3 phase motor for low voltage 230v as opposed to 460v in order to connect the motor to a vfd.
This apparently involves the windings and associated wire configuration.
Im just trying to better understand how to know if it is high or low voltage when wiring a motor.
A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac.
