To answer this question the supply voltage and the amperage of the load must be given.
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 25 amps for 400 feet on a 120 volt system.
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
The nominal voltage in the UK is 400/230 V. That is 400 V line-to-line (i.e. line voltage), and 230-V line-to-neutral (i.e. phase voltage). Allowable variation is +10% and -6%.
1/0 <<>> This is a voltage drop question. A voltage and whether it is a single or three phase system must be provided to give an answer.
The main difference between a 1n4004 and a 1n4007 are in the maximum RMS voltage, the maximum DC blocking voltage and the maximum repetitive peak reverse voltage. These are 280 and 700, 400 and 1000, and 400 and 1000 volts respectively.
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 25 amps for 400 feet on a 120 volt system.
you have to be over 400 feet to get over the wall
you have to be over 400 feet to get over the wall
400 feet = 121.92 meters
400 by 400 feet = 160,000 square feet 160,000 square feet = 3.6730946 acres
400 m = 400/0.3048 feet
400.
400 meters = about 1,312.34 feet.
Must also know current load to determine.
400 meters = 1,312.33596 feet.
A 1000 MCM copper conductor will limit the voltage drop to 3% or less when supplying 150 amps for 400 feet on a 120 volt system.
Answer: 400 m = 1312.335 ' OR 1312 ' and 4.03 "
