The above is great in theory but as soon as you start adding some length to
those cables you better start using your wire size calculator.
For a 100' cord off of a 15A plug you had better use larger than 14 ga if
you
want to limit your voltage drop to 1% the recommended wire size is 4 ga.
Your chart says that should handle more than 50 A but your chart also does
NOT include anything for length of run which becomes the more important
the closer to the amperage rating of the circuit the load becomes. Ignore
to your own cost and peril.
