A 2/0 copper conductor with an insulation factor of 90 degrees C is rated at 185 amps.
A motor feeder by code has to be 125% greater than the motors full load amperage. Therefore 175 x 125% = 218 amps.
A 4/0 copper conductor with an insulation factor of 90 degrees C is rated at 235
amps.
The minimum size home wiring is #14 AWG, the rating for that size wire is 15 amps.
The minimum size home wiring is #14 AWG, the rating for that size wire is 15 amps.
Most lamp wire is parallel #16 conductors.

The minimum size home wiring is #14 AWG, the rating for that size wire is 15 amps.
That depends on the voltage of the motor and the circuit. A 40 HP motor is a fairly large motor. If you don't know the answer to your own question, it's unlikely that you're qualified to wire it. Better consult and/or hire a qualified commercial electrician.
For a typical use it would be 1/0 (one ought) wire in copper.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.

Most lamp wire is parallel #16 conductors.
Depends on the current rating which should be on the motor.
Wire size for any piece of equipment is based on the equipments load amperage. The higher the amperage that larger the wire size has to be. For motor loads the motor's amperage has to be increased by 25% to size the conductor. Example, a 10 amp motor load current plus 25% equals 12.5 amps. This would boost the wire size from a #14 to a #12 conductor. This additional amperage increasing is also used for transformer conductor sizing.
