My 230v system consists of a ring main, with an RCD and the earth bonded to the hull by a large steel bolt, which is purely for use with a shoreline.
However, with no access to shoreline, I am planning to put in an invertor (cheap 800w modified sine job), using the already provided 3 pin plug changeover system.
This presumably means that the output of the invertor is earthed, however, there is a further wing-nut for earthing on the invertor itself. Should I connect a wire from this to the bolt into the hull?
Many thanks in advance!
