This is a voltage drop question. To answer this question a voltage has to be stated. The higher the voltage to the circuit becomes the smaller the wire size needed. After a certain voltage point the wire size will remain constant and the voltage drop at the load will become smaller.

This is a voltage drop question. Since it is connected to a home both voltages will be stated.
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 100 amps for 250 feet on a 240 volt system.
A 400 MCM aluminum conductor will limit the voltage drop to 3% or less when supplying 100 amps for 250 feet on a 120 volt system.

∙ 10y agoNormally you would use AWG # 3 wire for a service entrance. But considering you are running this 200 feet you need to go with AWG # 2 wire to have an acceptible voltage drop of only 2.60%. You will then have 233.75 volts which is acceptible.

∙ 12y agoThis is a voltage drop question. To answer this question a voltage value must be stated. Since it is a 100 amp panel the assumption will be made that the service is a 120/240 single phase.
A #500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 800 feet on a 240 volt system.

What size ground wire for a 30 kva transformer?
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
What size of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
What size ground wire for 100a service?
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
How do you size wire for a step down transformer?
You size it by the current required by the secondary, and the primary will be smaller wire.

What size ground wire should you use on a 1200 amp service?
You need to say whether it's a 150 amp service or a 1200 amp service it has to be one or the other. <<>> A 1/0 copper conductor with an insulation factor of 90 degrees C is rated at 155 amps. There is no ground wire stated for a 150 amp service so the next size up is a 200 amp service. The ground wire for this size is #6 bare AWG. Without knowing what types of loads that are coming off of the distribution a reduced neutral can not be recommended. The neutral will be the same size as the service conductor which is 1/0.
What size wire is for 200 amps?
Service wire required is AWG # 3/0 copper.
What size wire do you need for a 100amp braker?
Service entrance wire should be AWG #3 copper.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
