Shore power cable.

[David2452]

I would have thought that the thicker the cable the lower the impedence, hence less voltage drop.

Indeed, I think perhaps I should have been clearer, the larger conductor cross section would be contra indicated by being oversize for the required voltage drop, i.e. you could get away with thinner less expensive cable for simple voltage drop requirements but the extra robustness of the cable is probably better up a mast, and on the ground.

I think the confusion arises from your idiosyncratic use of the word contraindicated. You seem to be using it as a synonym for unnecessary or superfluous, while in general use it means "likely to be harmful".

The indicated/contraindicated dichotomy is a classical piece of medical obfuscation (and I write as an experienced medical obfuscator). To tell someone with condition X that treatment Y "is indicated" sounds better than saying it is our best guess for what might help. Similarly, when the Consultant at the bedside counters a suggestion from a junior colleague with "I think that would be contraindicated in this case" it is less likely to cause alarm than saying "that would probably make the patient worse or even kill them".
