To answer this question the following is needed. The voltage of the circuit, whether single or three phase. To calculate whether additional de-rates have to be applied the type of wiring system should be stated, overhead, direct bury or conduit system.
A single conductor single phase will need a #3 copper conductor and will limit the voltage drop to 2.93% when supplying 30 amps for 250 feet at 120 volts.
A single conductor single phase will need a #6 copper conductor and will limit the voltage drop to 2.76% when supplying 30 amps for 250 feet at 240 volts.
A single conductor single phase will need a #8 copper conductor and will limit the voltage drop to 2.16% when supplying 30 amps for 250 feet at 480 volts.
A single conductor single phase will need a #10 copper conductor and will limit the voltage drop to 2.62% when supplying 30 amps for 250 feet at 600 volts.
A single conductor three phase will need a #10 copper conductor and will limit the voltage drop to 2.84% when supplying 30 amps for 250 feet at 480 volts.
A single conductor three phase will need a #10 copper conductor and will limit the voltage drop to 2.27% when supplying 30 amps for 250 feet at 600 volts.

Single phase or 3 phase it doesn't matter. 30 amps is 30 amps.. Above your head or in the ground its still 30 amps.. 10awg is usually good for 30 amps but, with this voltage drop I would run 6awg.

What gauge wire 800 watts in 100 feet?
This is a voltage drop question and a voltage needs to be stated.
What wire size to use from breaker box to earth ground rod?
The wire size used in a service entrance distribution panel is governed by the size of the services over current device. The larger the service, the larger the fault current could be, the larger the ground wire to carry the fault current to ground. If the largest service conductor carries 100 amps use a #8, 200 amps - #6, 400 amps - #3, 600 amps - #1, 800 amps - 1/0 and over 800 amps - 2/0 for the ground wire. <<>> Golden Valley Electric Assoc. in Alaska requires #4AWG copper wire for a ground from the breaker box to earth ground rod. The same goes from the service entrance panel on the pole.
What size ungrounded conductor for 800 amp service?
A 3/0 copper conductor would allow you up to 100 feet at 800 Amps with only 5 percent voltage drop, assuming 240-volt service. If it were a 3-phase 480-volt service, you could go more than 23 feet with only a 5 percent drop. <<>> The size of conductors for an 800 amp service could be sized in several ways. Using a single conductor is out of the question as the size will be impossible to bend or handle. A 2000MCM wire only has a rating of 775 amps. Most high amperage services will use parallel runs to add up to the required amperage. A parallel run of 600 MCM will give you a total of 910 amps. A triple parallel run of 300 MCM will give you a total of 885 amps. A quad parallel run of 3/0 will give you an amperage of 840 amps. The key here is to find the most economical way of installing the service. Take into account the availability of triple barrel or four barrel lugs, wire costs for the larger sizes and the labour to man handle the larger sizes into the main switch. These size services that I have installed, the customer opted for the four barrel lugs with 3/0 wire. The 3/0 wire is a readily available item even though the lugs may have to be a special order.
What size ground wire should you use on a 1200 amp service?
For a 1200 amp service, you should use a copper ground wire of at least 3/0 AWG or an aluminum wire of at least 250 kcmil to meet the National Electrical Code requirements. It's always recommended to consult with a licensed electrician to ensure the proper sizing and installation of the ground wire.
How many inches are there in 800 feet?
There are 12 inches in one foot. Therefore, 800 inches is equal to 800/12 = 66.6 recurring (that is, 66.666..) feet or 66 feet 8 inches.800 inches = 66.66 feet
What size wire needed for 50 amp service 800 feet away 120 volt RV Trailer 3600 watts plus a security light or outdoor outlet What size breaker at the supply disconnect receiving panel disconnect?
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 800 feet on a 120 volt system. 500 MCM wire diameter is 1/2 inch. As you can see there will be trouble getting that size wire into a 50 amp breakers lug. On installations like this to offset the voltage drop at such a low voltage, a transformer should be used at both ends. The first transformer to raise the voltage and the second transformer to lower it at the 800 foot end. If you use two 480 volt transformers a #1 wire can be used between them. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 800 feet on a 480 volt system. By increasing the voltage you can see that a smaller wire size can be used. On an installation of this nature, a primary line should be brought to the RV site and a service distribution panel established at that point and any RV vehicles can then be fed from that service.

What wire size for 15000 Volts and 550 amp service?
There are two distinct questions here. To determine the wire size to carry 15000 volts the circuits load amperage must be stated. The wire size for a 550 amp service is, an 800 MCM copper conductor with an insulation factor of 90 degrees C. This conductor is rated at 555 amps. Parallel 250 MCM will give you a total capacity of 580 amps. A triple run of 2/0 will give you a total capacity of 585 amps.
