Depends on what it is powering. The longer the run the more voltage drop you get. For example if you run 200 feet of copper 10 wire you'll lose about 4 volts. There are voltage calculators you can use. The less volts you have the more amps the wire will have. Watts/volts=amps. 10 wire is rated for 30 amps. Do the calculation. You should not go past 80% of 30 amps (24 amps).

What wire size for 100amp load for distance of 1000ft?
At that distance you will have a voltage drop of 81.25 volts if you use the recommended #6 wire on a 240 volt, 100 amp single phase circuit. Therefore I recommend you contact you electric utility and let them figure the voltage drop and the size wire required to safely run this distance. Using too small a wire can damage the electronics at the end of the run.
What size wire do you need to run overhead to a 50 amp service five hundred feet away?
For that distance I would run AWG # 3 copper and install a sub-panel.
Can I run a double 30 amp breaker with 10-3 wire to receptacle for 240v MIG welder. Distance from main box to destination is 60 feet.?
Yes.
What wire size is good for 100 amps?
# 4 copper wire short distance.
What about distance of 14 gauge wire?
It depends on the load applied. With a load of 10 amps you would loose 5 volts at 100 feet. I would not run it over 50'. This is one of the reasons I never wire any home with AWG#14 wire even though you can use it in bedrooms. I prefer to use AWG #12.
