The client had observed that the newly refitted boat tripped
the marina RCD when plugged in. Inspection showed that the installer had
reversed the neutral and earth. In addition the client's shore cable had
the live and neutral reversed. In effect, all 'earthed' equipment was
live, and as the hull wasn't earth bonded, there was no path to earth
for fault current. Fortunately the marina RCD was in working order, however
it would have been a different story if a genset or inverter had been
used on the way from the builder to the home mooring.(No RCD had been
fitted to the boat's system) |
