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.
This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
Assuming you are working with 240v, you need 4/0 copper conductors.
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 60 amp service: At 750 feet away, you would need at least #4 copper or #2 aluminum wire to account for voltage drop. At 500 feet away, you could use #6 copper or #4 aluminum wire for the same purpose.
It depends on the length of the run

AWG 2/0 copper.
To span a distance of 20 feet, a lumber beam of at least 2x10 size is typically needed for adequate support.
For that distance I would run AWG # 3 copper and install a sub-panel.
Need to know what size service is going to be installed at the end of the run.
A 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 200 feet on a 240 volt system.
Assuming you are working with 240v, you need 4/0 copper conductors.
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
# 6 copper wire.
200 amp service in chicago uses 3 aught.
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.
