Good day all.
I have a question regarding wire size. If I look at the tables in AC 43.13 I see that for a wire length of 20 feet and a current of 6 amps I would need a #14 wire. Now for my question, If I decide to not locally ground the device , for example a landing light in the wingtip , and decide to run a dedicated ground wire as well does the "effective" wire length then go up to 40 feet ( out and return ) and therefore a larger diameter wire will be needed. Or do I only have to consider the wire length from the switch to where the current will be consumed? I hope my question makes sense ...
