== == 125 Amps is a very heavy current load for a household circuit so this 340 ft run may be for some industrial plant or equipment... You really should know how to handle wiring size calculations already before you install that kind of stuff.
<><><> To do a proper calculation, working voltage is needed, whether it is single phase or three phase and whether the wire is copper or aluminium. Single phase - 125 amps at 120 volts, copper wire #3/0, 125 amps at 240 volts, copper wire #1 Three phase - 125 amps at 480 volts, copper wire #4 ----- As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

∙ 14y agoThe size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
This is a voltage drop question. To answer this question a voltage must be stated.
AWG # 10
2 AWG.
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
For a 30 amp load at 12 volts DC over a distance of 34 feet, a wire size of at least AWG 8 would be recommended to minimize voltage drop and ensure efficient power delivery. It is important to consult with local electrical codes and standards to ensure compliance with regulations.
AWG # 10 wire on 30 amp circuit.
For a 15 amp circuit over 200 feet, it's recommended to use a 12-gauge wire to ensure proper voltage drop and safe operation. This larger wire size helps to minimize voltage drop over the longer distance and reduce the risk of overheating.
Wire size is calculated from the amount of current the load draws. More information is needed. Voltage and amperage will do fine.
The wire size needed for a 180' run depends on the voltage, current, and type of installation. It is recommended to consult the National Electrical Code (NEC) and a professional electrician to determine the appropriate wire size to ensure safety and compliance with regulations.
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
The length of wire needed to make a slinky can vary depending on the size and number of coils. A standard slinky typically contains about 67 feet of wire.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
For a 25 amp load at 220 volts over a distance of 75 feet, you will need a 10-gauge wire to ensure safe and efficient electrical conductivity. This wire size allows for minimal voltage drop and meets the necessary ampacity requirements for the circuit. Make sure to consult local electrical codes and regulations before installation.
Wire size is based on the amperage of the load. Without knowing what the motors's full load amperage is, an answer can not be given.
For carrying 100 amps underground, typically a 2-gauge copper wire or a 1/0-gauge aluminum wire would be suitable. It's important to consult with a licensed electrician to ensure the correct wire size based on distance, voltage drop, and local electrical codes.
