This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
A 350 MCM copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 650 feet on a 240 volt system.
10 AWG in copper.
AWG 4 copper.
Assuming you are working with 240v, you need 4/0 copper conductors.
For a distance of 450 feet, you would need, 2 sets of #4/0 (parallel 6 conductors) for aluminum, or 1 set of #350 copper.80% loading of service and a 3% voltage drop.Consult your local power company for exact requirements of their codes.
AWG 2/0 copper.
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.
# 6 copper wire.
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
A 350 MCM copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 650 feet on a 240 volt system.
10 AWG in copper.
AWG # 4 copper.
This is a voltage drop question. A 300 MCM copper or a 500 MCM aluminium conductor will limit the voltage drop to 3% or less when supplying 200 amps for 450 feet on a 240 volt system. The cheapest of the two conductors would be the aluminium conductor. For direct burial is will have a ACWU 90 designation.
AWG 4 copper.
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.
Assuming you are working with 240v, you need 4/0 copper conductors.
For a distance of 450 feet, you would need, 2 sets of #4/0 (parallel 6 conductors) for aluminum, or 1 set of #350 copper.80% loading of service and a 3% voltage drop.Consult your local power company for exact requirements of their codes.
