CarpeDiem 430 Posted November 6, 2021 Share Posted November 6, 2021 I have a Bronze sintered grounding plate on the hull for the SSB. Very similar, if not identical, to the smallest of these: The SSB has a wide/thin copper tie, 2" +/- wide x 1mm that connects to this. Why does it use a copper strip instead of just a wire? Can I use this as my EWOF marina AC earth? Thanks Quote Link to post Share on other sites
Island Time 1,235 Posted November 6, 2021 Share Posted November 6, 2021 Not for commercial survey. Most private vessels don't have ground plates. You don't have to have a ground plate for an ewof. Your ac ground should be connected to your DC ground (bus bar, engine, whatever it is) at ONE location only. IMO you should have a galvanic isolator in the AC ground, near the shorepower connection. This is only strongly advised in the regs. The SSB uses flat copper strap as it works better than a cable for RF grounds. Round cable is not great for a ground plane connection. This is NOT an electrical ground, but an RF ground, they are very different! 1 Quote Link to post Share on other sites
