My solar panels
use 12ga wire to the main panel.
I would like to add a analogue amp gauge into the circuit.
The gauge I have has 18 or 20ga wires 6” long each (total length 12”) to go in series With the 12ga wires. This length could be shortened.
I know that shorter length of wires can carry larger amps, but this seems to drastic.
Amperage is often equated to water
. Larger pipes (wires)can carry a larger flow of water
(amps). If a smaller pipe(wire) is installed it reduces the flow of water (amps).
It would seem that installing a 18/20 ga length of wire would have a similar effect.
I could install a digital gauge with no effect on the wiring
size, but I was looking for the increased accuracy of the analogue gauge.
Comments would be appreciated.
