Hello, To use this calculator enter the size of the wire in SWG,
Enter the number of lead wires (parallel) in the count field.
Similarly do the same for the rest of the sizes
If you want to add more sizes use the add size button,
to add-on another row to input the size
The value indicated by -2 to -7 corresponds to '00 SWG' to '0000000 SWG' and
Use SWG 100 to indicate '0 Sq mm' area (to not use a row).
Better option of doing so is by refreshing the page.
