Note:

All distances are in FEET.

Do not use any wire sizes that might fall into the red zone – this would exceed the amperage rating of the wire and it may overheat and burn.

These are one-way distances, measured from point A to point B. The out and back nature of electrical circuits has already been included. For PV arrays, figure the entire run, from the panels to the charge controller to the batteries.
