This is a voltage drop question. A 500 MCM copper or 750 MCM aluminium conductor will limit the voltage drop to 3% or less when supplying 300 amps for 500 feet on a 240 volt system. Paralleling these conductors will allow the rating to be increased to 600 amps.

What are the Advantage of three phase motors over single phase?
A 3 phase system needs only to use 3 or 4 conductors, as against 6 conductors if it were 3, single phase conductors The amount of copper used in a 3 phase is much less than what would be needed in a single phase system carrying the same current, this reduction in copper allows for weight reduction and cost savings. The power losses in a 3 phase system are much less than in a single phase system.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
How single phase preventer working?
working of single phase preventor

The power losses in a 3 phase system are much less than in a single phase system.
What type of wire you used in three and single phase line?
Copper or aluminum wires.
What are the advantages of poly phase over single phase?
The primary advantage is that, for a given load, a three-phase system requires less copper for tranmission/distribution than an equivalent single-phase system would require. Other advantages include the fact that three-phase machines are smaller than single-phase machines of similar rating.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
Why you cant transmit high voltage through single phase?
You can, but for a given load it's more economic, in terms of the amount of copper used, to use three-phase.
Is there any other wires colors used for grounded other than gray and white?
In industrial wiring 'three phase' green or bare copper is the norm for a ground. In home wiring 220/110 single phase, bare copper is the ground
What are the advantages between 3 phase and 1 phase?
For a given load, a three-phase system uses less volume of copper (therefore is more economical) than a corresponding single-phase system, while supplying approximately-constant power. From the users' point of view, three-phase motors are self-starting and more compact than the equivalent single-phase motor.
What size service conductors do you need for a single phase 600 amp commercial panel?
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
What are the uses of three phase transformer over single phase and their losses?
For a given load, a three-phase system requires around 75% of the volume of copper required by a corresponding single-phase system and, so, is more economical. A three-phase supply also delivers power more or less continuously, whereas a single-phase supply delivers power in pulses. Finally, three-phase motors are self-starting and physically smaller than single-phase machines of the same power rating.
Why you use brushes for single phase induction motors?
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
What is the advantage of polyphase system over single-phase system?
1) less copper cross section to conduct current2) constant power to load3) constant rotating magnetic field4) Ideal for Direction Reversing5) Current is not zero at any constant..
