The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.
110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.
At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.

For 225 kw motor what is the amps star and delte and what is the cable size required?
Need to know what the voltage of the motor is.
What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
How many amps does a 110 volt 1.3 kw motor draw?
110 volts divided by 1,300 watts(1.3 kw) = .09 kw or 900 watts.
What cable size to use for a 1 kw motor for a 400v 50 hz 3 phase supply?
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
An electric motor under steady load draws 9.7 amperes at 110 volts delivering 1.25 hp of mechanical energy What is the rate of the heat transfer from the motor in kW?
As the motor is drawing 9.7×110 = 1,067 watts (or 1.067 kW), and delivering 1.25×746 watts (or .9325 kW) of mechanical energy, it should release 1,067-932.5 = 134.5 watts (or .1345 kW) of heat.

Which size cable use for 37 kw induction motor?
For a 37 kW induction motor, a cable size of approximately 10 AWG (American Wire Gauge) would be suitable for typical installations. However, the specific cable size required would depend on factors such as the length of the cable run, ambient temperature, and voltage drop considerations. It is recommended to consult with a qualified electrician to determine the appropriate cable size for your specific application.
How many amps does a 110 volt 1.3 kw motor draw?
110 volts divided by 1,300 watts(1.3 kw) = .09 kw or 900 watts.
What cable size to use for a 1 kw motor for a 400v 50 hz 3 phase supply?
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
What size wire should be use for connecting a 110 kw motor over a distance of 108 meters?
This is a voltage drop question. To answer this question a voltage must be given.

Could you Calculate cable size for 100 kw load?
Yes I could. How?
How do you calculate XL-PE cable size for 6.6 KV 300 KW motor?
Find out how much current the motor draws, then look up wire tables to find out the size of wire. Ask an electrician if you are not unfamiliar with this because working at 6.6 kV is definitely lethal for the unqualified.
What is the cable size for 7.5 kw 3 phase motor?
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.
For 100kw which cable size is good and how to find out cable size?
100 kw is the power drawn by the load. to calculate the cable size you need to know the voltage. From that you can calculate the current. this decides the cable size. for example if the voltage is 400Volts then the current flowing in the circuit when the load is 100 KW will be 250 amps. (100,000/400). for 250 amps to flow with out causing excessive heating of the cable the cross sectional area of the copper cable should be 150 sq mm.for a round cross section the diameter will be roughly 15mm.
What is the armour cable size for 45kw 3phase ac motor 2965rpm?
At 2965 rpm it sounds like an induction motor for a 50 Hz supply. A 45 kW motor would draw about 55 kW from the supply with a power factor of 0.85, so that is 65 kVA, and on a 415 v 3-phase supply that is a current of 90 amps. For armoured XLPE cale the size needed is at least 16 mm2 Probably 25 mm2 would be preferred for a permanent installation but it would depend on how the cable is installed, how much free air movement there is around it etc.
