hello I have jut installed shore power
in the yacht, and after plugging it in, I am getting electric
shocks from my laptop! this seems odd, because after passing through its transformer the current
into the laptop
should / can only be 70W.
the shore power
is earthed on shore, with a 10A RCD there. on board, the power passes through a 30A RCD,
the earth wire is earthed to a CGP, on the hull
below the waterline .
chassis becomes live, when plugged in to the power socket on the yacht.
how? why? is the 'double earth' creating a circuit? any other ideas?!
