To calculate the wire size for a 5.5kW motor a voltage is needed.
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can different size conductors be used on a three phase supply?
In normal use a 3-phase supply is balanced so that the three phase wires would be of equal size because they carry equal current. When in balance the system draws no current in the neutral wire (if present). In some conditions different currents are taken from a 3-phase supply, for example three houses connected to the different phases will probably take different currents, and in that case the neutral could carry a current up to or equal to that in one of the phase wires. Therefore in supplying a street, the four wires of a 3-phase supply would all be of equal size.
Computation of three phase motor 230 volts 20 hp in what size of wire?
A 20 HP three-phase motor operating at 230 volts will draw approximately 45 amps. You would typically use a wire size of at least AWG 8 for this application. However, it's recommended to consult the National Electrical Code (NEC) and a qualified electrician to ensure compliance with local regulations and safe installation practices.
What is the size of XL PE cable for 380 Volts in 125 KW motor?
If it's a 380 v 3-phase supply, the current is up to 300 amps which could be supplied over a short distance by XLPE cable with 70 sq. mm cross-section conductors.
Why neutral cross section is half the phase in three phase cable while it has to carry current of summation of all phase..?
The current carried by the neutral of a three phase four wire system is the un balanced current. If the three phase system was completely balanced on all three phases there would be no need for a neutral, eg a three phase motor. This neutral current will be less that the phase current so a reduction in the neutral size is allowed.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
What size swa cable is required to supply a door heater carrying 18.9Amps per phase?
Cable for 19 amps continuous should have a cross-section area of 6 mm2.

Can you run 22 kw 600v 3 phase induction motor?
Yes this size motor can be operated by bringing a 600 volt three phase supply to it.
Why you use only single phase and three phase supply?
Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.
What is the cable size for 1.5KW 3 phase induction motor?
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
What size cable for 50 amps 3 phase for 650 meters length?
70mm 4core copper cable
What size tech cable for 480 feet 100 amp?
This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.
What is the breaker size for a10kw 380v 3 phase power supply?
10amp
What size cable required for3 phase 128 watt?
To answer this question a voltage is needed.
How much current will flow in neutral line for three phase supply 100amps?
If all three legs of the system are balanced then zero amps will flow all the way up to 100 amps if only one leg of the three phase system is used. The neutral in a wye three phase system carries only the unbalanced current. This is why in services for a three phase four wire system you are allowed to reduce the size of the neutral conductor.
What size generator for 1600 amps three phase supply?
copper wire diameter,length and numbers of turns for 20 micro Henry inductance and 1600 Amp current
