For single phase 30 amps at 120 volts you would need a #8 copper wire with an insulation rating of 90 degrees C.
This 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.
A 100 foot fish tape and wire lubrication will be needed to make this wire pull.
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.
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.
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.
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.
To determine the wire size needed for a 100 amp load 250 feet away, you will need to consider the voltage and allow for voltage drop. For a 100 amp load at 120V over 250 feet, you would need a wire size of at least 1/0 AWG. It's recommended to consult with a licensed electrician to ensure proper wire size for your specific situation.
The size of wire needed for a trolling motor depends on the motor's maximum amperage draw and the length of the wire run. A general guideline for a 12V trolling motor is 6-gauge wire for runs up to 10 feet, 4-gauge wire for runs up to 20 feet, and 2-gauge wire for runs over 20 feet to minimize voltage drop and ensure proper performance. Be sure to consult the manufacturer's recommendations for your specific trolling motor.
Assuming you are working with 120v, you need #4 AWG copper conductors.
# 6 copper wire.
To wire a 120V A base emitter for 120V, you would typically connect the emitter to the ground, the base to the input voltage source (120V), and the collector to the load. Ensure you follow proper safety precautions and consult the specific datasheet for the A base emitter you are using for correct wiring instructions.
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.
