Any
Marine electricians out there?
Our two 110 outlet circuits have a CGFI outlet as the first device. I read a paper on
marine electrical standards, and it stated the
safety ground from the
shore power goes (and connects) to the CGFI device and no further, and
safety ground of the load outlets connect to the GCFI outlet, all downstream outlets and to the ships common ground. However, it also said the shore safety ground should not attach to the ships common ground. If both safety grounds attach to the CGFI device, are they not also connected to each other (and therefore to the ship's common ground?) (Ground is a common terminal.)
