This calculator is used to estimate the maximum current of a power wire based on the wire size and distance.

There are some basic causes low maximum current.

The first is the choice of material used for the wire. Copper is a better conductor than aluminum and will allow more current to pass through than aluminum for a given length and wire size.

Wire size is another important factor in determining maximum current. Larger wire sizes will pass more current than smaller wire sizes of the same length.
