β 11y agoThis is a voltage drop question. To answer this question a voltage must be stated.
Assuming you are working with 120v, you need #4 AWG copper conductors.
This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.
A 100 foot fish tape and wire lubrication will be needed to make this wire pull.
The wire size depends on how much current it will conduct.
Use AWG #10 wire on a 20 amp breaker.
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.
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.
A #3 copper conductor will limit the voltage drop to 3% or less when supplying 5 amps for 1500 feet on a 120 volt system.
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.
This is a voltage drop question. To answer this question a voltage must be stated.
You know the old saying: "If you have to ask..."! If you're asking this question, you should probably be calling an electrician. The answer to your question depends upon what you are trying to power up. This will determine what size wire you will need and therefore, the size of the circuit needed.
No, electrical code typically requires that circuits be protected by a breaker that matches the wire size. A 30 amp breaker is typically used for circuits with larger wire sizes. For a 120V circuit, a 20 amp breaker is more suitable with appropriate wire size.
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.
Assuming you are working with 120v, you need #4 AWG copper conductors.
A #4 copper or #3 aluminium conductor will limit the voltage drop to 3% or less when supplying 30 amps for 150 feet on a 120 volt system.
