Without knowing the nominal voltage rating, who can tell?
<<>>
The sizing of cables or conductors is based on the amperage that the conductor can safely carry. The formula for amperage is I = W/E. Amps = 12000/Volts. With out a voltage stated an answer to this question can not be answered. When you calculate the amperage, re-ask your question for a conductor size for a given amperage.
4 square for under a 20 meter cable run
You will need a 22mm wire.
That would depend on the type of motor and the manufacturer.
50 sq.mm of aluminium and 25 to 35 sq.mm of copper
you need the current of motor or the KW/HP rating
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
First of all find out what voltage the motor is designed to work on.

Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
50 sq.mm of aluminium and 25 to 35 sq.mm of copper
you need the current of motor or the KW/HP rating
i have 200 hp motor what i need cable size in 100 feet distance
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
First of all find out what voltage the motor is designed to work on.
Assuming it is a 400 V three-phase motor, the phase current is 11 amps, or more if the power factor is less than 1.0 (or the supply voltage is different). If it is a 400 V motor the cable should be capable of carrying 16 amps, so a 2.5 mm-sq 4-core cable is needed.
If I consider power factor is 0.85 & motor efficiency is 95% then you have required 4 sq mm wire which is able allow passing 25.47 A current trough it.
