Tim,

Yes, 4mm2 between sink and hot/cold pipes.

Thanks, Tim. Is that a cable from the sink to, say, the cold pipe and
a jumper cable connecting the cold pipework to the hot?


Yes, I never cut my cables. used to strip off insulation and then fit to
earth clamp by removing the screw completely to put wire under efore
tightening up again.(if that makes sense!)

But in no way is 16mm2 needed to your sink!

It did seem a tad large, I admit.
