What size copper wire do you need for 339 amps running 150 feet?

It would depend on the voltage, because at a higher voltage a larger voltage drop can be tolerated for the same percentage voltage drop. That means a thinner wire could then be used.
And 339 amps is a VERY high current for 120/240 volt system- more than double the peak demand for most houses. Please check your question, and give us the voltage used.

Need to run 30 amps about 100 feet what copper wire?
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.
What size wire needed for 100 amp service 700 feet away?
A 400 MCM copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 700 feet on a 240 volt system. This size will allow the conductor to be loaded to 80 amps. 100 x 80% = 80 amps. Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 100 amps then you would need to use a wire with a rating of 125 amps. 125 x 80% = 100 amps. A 600 MCM copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 700 feet on a 240 volt system.
What gauge of electric wire needed for a 160' run at 125 amps?
A 2/0 copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 230 feet on a 240 volt system.
What size electrical wire do I need to run from a meter main to a 200 amp panel 80 feet away?
A 3/0 copper conductor with an insulation rating of 75 or 90 degrees C is rated at 200 and 210 amps respectively. A 3/0 copper conductor will limit the voltage drop to 2% or less when supplying 200 amps for 80 feet on a 240 volt system.
What size wire do you need to run 1000 feet and still have a minimum of 60 amps?
Looks like You need to run #10 to get 10 amps at 600 feet. You will have a voltage drop. You might only have aprox. 107.676 volts at the end of the run. You will do a little better if you use strand wire. Good luck.
Need to run 30 amps about 100 feet what copper wire?
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.
What size in square mm copper wire will be required to carry 26 amps?
You will need a 40 amp breaker using AWG # 8 wire running it a distance of no more than 50 feet.
What wire gauge do you need for welder using 60 amps when runnung for a distance of 35 feet?
#6 awg copper
What size wire do you need for a 30amp 120 volt appliance. It will be run in steel conduit.?
A #10 copper wire with an insulation factor of 90 degrees C is rated at 30 amps. If you need the full 30 amps for the load use a #8 copper wire. Loaded to 80% of rating will give you 32 usable amps.

What gauge wire for 208 volt 95 amp 200 ft?
A #1 copper conductor will limit the voltage drop to 3% or less when supplying 95 amps for 200 feet on a 208 volt system. This size will allow the conductor to be loaded to 76 amps. 95 x 80% = 76 amps Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 95 amps then you would need to use a wire with a rating of 120 amps. 120 x 80% = 96 amps. A 1/0 copper conductor will limit the voltage drop to 3% or less when supplying 120 amps for 200 feet on a 208 volt system.

What size wire to run 400 ft from main panel need 60 amps?
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
