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.
What else can I help you with?
What wire size needed for 150 amp service at 325 feet Copper or Aluminum?
This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
What size service cable for 100 amp main panel 100 feet away?
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.
What size wire do I need for a 60 amp service either 750 feet or 500 feet away?
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.
