@stuart and @GadgetUK, what am I missing?
When measuring the voltage, the amps will be nil, thus the voltage drop should be insignificant. During bypass, I don’t see why we care that a long cable is adding resistance. The module will not measure the V (or rather should not measure) while it is bypassing.
The ampacity tables tell us the max amps to run through a cable to ensure the cable does not melt, and that is length independent.
