Assuming its copper. Number #3 or #2 is fine
That can't be answered until you state the voltage.
For a 100 amp service, a common feeder wire size would be 2 AWG (American Wire Gauge) copper or 1/0 AWG aluminum. These sizes are appropriate for handling the current capacity needed for a 100 amp electrical service. It is important to consult with a licensed electrician or local building code requirements to ensure the proper wire size for your specific installation.
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.
I would recommend you use AWG # 2 copper or AWG # 1/0 aluminum for that distance and amperage.
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.
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.
For a 100 amp service running 200 feet, the recommended wire size is typically 2 AWG copper or 1/0 AWG aluminum to ensure proper electrical conductivity and safety.
For a 100 amp service running 150 feet, the recommended wire size is typically 2 AWG copper or 1/0 AWG aluminum to ensure proper electrical conductivity and safety.
The recommended copper wire size for a 100 amp service is typically 3 AWG (American Wire Gauge).
The recommended wire size for a 100 amp aluminum service is typically 2 AWG (American Wire Gauge).
That can't be answered until you state the voltage.
For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
This is a voltage drop question. A voltage must be stated to answer this question.
For a 100 amp service, it is recommended to use aluminum wire that is at least 2 AWG in size.
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
