Use AWG #10 wire on a 20 amp breaker.


How many feet of wire to make a slinky?

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.


What size wire needed for 25 amps 220 volts for 75 feet?

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.


What size wire do you need to feed a 5 amp load run 1500 feet from the main at 120v?

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.


What size wire is needed for carrying 100 amps under ground?

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.


What wire size needed for 150 feet run on 30 amp?

This is a voltage drop question. To answer this question a voltage must be stated.


What do you have to know to install a 120v electrical line?

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.


Can you have a 120v circuit on a 30 amp breaker?

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.


What gage wire do you use for 15 amps 200 feet?

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.


Is number 10 wire good for a 20 amp circuit that is 250 feet?

Assuming you are working with 120v, you need #4 AWG copper conductors.


What size wire should I use for a 120v 30amp 150 foot long run?

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.
