If a 460V compressor is rewired for use in Canada, what will be different regarding the wiring?

The choice indicating the compressor will be rewired for 208V and that the current draw will double is correct due to the electrical standards and practices in Canada.

In Canada, the standard voltage for three-phase systems often includes 208V configurations, particularly in commercial settings. When a compressor designed for operation at 460V is adapted to run on a 208V supply, it is necessary to reconfigure the wiring, usually by changing the tap settings or altering the motor connections. This rewiring allows the compressor to operate correctly at the lower voltage.

Moreover, when reducing the voltage to 208V, the power requirement does not change, which can lead to an increase in current draw. Since power (in watts) is the product of voltage (in volts) and current (in amperes), if the voltage is halved (from 460V to 208V), the current required to maintain the same power output will effectively double. This doubling of current needs adequate consideration in system design and component ratings to ensure the system operates safely and efficiently.

The other options suggest incorrect voltage ratings or configurations that do not align with Canadian electrical standards or practices.
