It depends upon whether you mean 240 volts at the first end or the second end.
Assuming 240 volts at the source, and allowing no more than a 3 percent voltage drop over the 200-foot circuit, at 100 percent load of 100 amps, you would need a #1 copper conductor. You would only have 233 volts at the far end at full load.
Note that if the ampacity of conductors supplying your connection point is not sufficient, the "supplied voltage" on your new extension could be substantially diminished under load. For instance, if you are already 100 feet from the original 240 volts, your extension would have an effective circuit distance of 300 feet, requiring #2/0 conductors.
This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
Yes, as long as it has the necessary ampacity for the load and is properly fastened at each terminal. For example, we have a 4/0 aluminum cable feeding our 200 A subpanel 120 feet away.
For a 200 amp service running 650 feet, you would likely need at least 2/0 aluminum or 1/0 copper conductors for the hot lines. The size of the neutral conductor will depend on whether it is required to be the same size as the hot conductors or smaller, and the size of the ground conductor will need to follow local electrical code requirements. It is recommended to consult with a qualified electrician to ensure proper sizing for your specific application.
For a 100 amp main panel located 100 feet away, it is recommended to use a 2/0 copper or 4/0 aluminum service cable to ensure proper voltage drop and capacity for the distance. Consult with a licensed electrician to determine the specific requirements based on local codes and conditions.
For a 100 amp service located 160 feet from the power pole, it is recommended to use 2 AWG copper wire or 1/0 AWG aluminum wire to ensure proper voltage drop and safety. Be sure to consult with a licensed electrician to determine the specific requirements for your installation.
Your service provider will give you that information The size will depend on: A) how close to the transformer are you. B) copper or aluminum C) Yes, you have a 400amp service but what will your actual peak amp usage be. D) Underground or overhead.
I would use AWG #4 for that run in alluminum. You will have a 3.8% voltage drop which is acceptible.

# 6 copper wire.
A 1/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 30 amps for 500 feet on a 240 volt system.

This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
If you do not have a underground metal water pipe coming into the building then you put a ground rod at least 2 feet from the buildingf into the ground attach one end of the wire to ground rod run your ground wire and attach the other end to the neautral bar in the panel box. You need special transformer called as grounding transformer for this purpose. Grounding transformer is basically Wye-Delta type transformer with Wye connected winding connected to 3 line wires and derived neutral from Wye side grounded through desired grounding device. Delta side winding of grounding transformer is kept at no load.
For a 100 amp service over a distance of 100 feet, the recommended wire size is typically 2 AWG copper or 1/0 AWG aluminum.
The underground railway was NOT underground. It was a trail leading the black to safety.
