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.
It depends on the supply voltage because at that distance the size of the wire is calculated on the volt-drop which is 5% of the supply voltage, or 3% in some countries. The allowable resistance equals the volt-drop divided by the current, then you can use wire tables to find the wire size, remembering that a supply needs 2 wires which are in series so that their resistances add. <<>> To answer this question a voltage value has to be stated. This is due to the higher the voltage the lower the current on a specific load. The lower the current, the smaller the wire size can be.
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.
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.
200 amp service in chicago uses 3 aught.
