A rather thin copper or aluminum wire.
3/0 gauge
Use 8 gauge wire.
A 12 gauge wire can support a load of approximately 2200 watts.
Wire is sized by the amperage of the load. Without knowing what the load amperage,the voltage and whether the load is three phase or single phaseat the dock, an answer can not be given.
For a 50 Amp load, a 6-gauge aluminum wire would be suitable for most installations. It is important to consult local electrical codes and regulations to ensure compliance with safety standards.
Copper wire gauge sizes are not equivalent to aluminum wire gauge sizes. The gauge sizes for copper and aluminum wires are different due to their differing electrical conductivity properties. It is not possible to directly convert a copper wire size to an equivalent aluminum wire size.
The lower gauge number is always a thicker wire which can carry more current.
The weight of aluminum wire per foot depends on its gauge or thickness. On average, a 1000 aluminum wire with a gauge of 10 (0.1019 inches diameter) weighs approximately 0.628 pounds per foot. The weight may vary for different gauges of aluminum wire.
A rather thin copper or aluminum wire.
it is not recommended because the 14 gauge wire is not capable of carrying the same amount of load as the 12 gauge wire which could result in a fire.
A 100 gauge piece of aluminum has a thickness of 0.0010 inches. Gauge is a universal system used to measure the thickness of metal and wire.
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.
6 gauge
3/0 gauge
Use 8 gauge wire.
Loaded question, what is the voltage, run length, aluminum or copper feeders, expected constant load? Definitely bigger than 4/0
