Use the Related Link Website. At the same website check out wire size calculator. You need a #8 wire to get a full 30 load at 100 feet.
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.
A #14 copper wire with an insulation factor of 90 degrees C is rated at 15 amps. To answer your question for voltage drop at 200 feet a voltage needs to be stated. Assuming the voltage of 120 is used to maintain 15 amps at the distance of 200 feet a #6 copper conductor will limit the voltage drop to less that 3 percent. Assuming the voltage of 240 is used to maintain 15 amps at the distance of 200 feet a #10 copper conductor will limit the voltage drop to less that 3 percent.
Because of voltage drop, 4 awg copper would be recommended for that distance run. <<>> A #1 copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 200 feet on a 110 volt system.
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
This is a voltage drop question. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 240 volt system. Or a 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 120 volt system. In your question you sis not stipulate what the working voltage is.
I would recommend no smaller than #8awg copper. This is derived by 8awg copper ampacity of 40 amps multiplied by 80% load rating to get 32 amps. Then calculating for voltage drop over this distance shows a drop of 5.9 volts or 2.5% which is negligible so not accounted for. So like i said no smaller than #8awg copper.
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.
A #16 copper conductor is not a wiring size that is used in homes. This is because the smallest breaker for residential use is rated for 15 amps. A #16 copper conductor is only rated at 13 amps. For a load of 13 amps over 100 feet a #12 copper would be required.
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.
This is a voltage drop question. To answer the question about distance a voltage must be stated. That said a #10 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 30 amps.
Yes. When the voltage drops and the power requirement (watts) stays the same, the amperage goes up.
A #8 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 50 and 55 amps respectively. When distance comes into the equation, the question becomes a voltage drop question and a supply voltage over the 200 feet has to be stated.
