I was visiting with a previous survey customer today who mentioned that a couple marinas in south florida were installing GFP type breakers on pedestals. Some boat owners were unable to utilize these due to onboard electrical issues. He asked how he could test his own boat to insure he would not have problems. I suggested he might try using an adapter to plug into a 15 amp GFCI (5 milliamp trip) and see how his system performed. Obviously one wouldn't run too many loads while performing this test. I think it would be a hyper sensitive test that might provide some peace of mind or warning prior to running into trouble unexpectedly at a later date. If you can keep a 5 milliamp outlet happy you should be able to run well on a 30 milliamp trip point.
GFP and ELCI breakers will be coming more and more into play. In addition, on surveys where a vessel has no main breaker or defective main breaker I am recommending installation of ELCI type as replacement. They really do improve boating safety but require other areas of the system be in good working order. It might even be a good topic to have its own discussion on the TF. Nuisance trips can be generated in a lot of different ways so a checklist of practical experiences would be beneficial for those who become entangled.
Here is some info from Blue Sea Systems: https://www.bluesea.com/resources/1..._Interrupters_[GFCIs]_to_make_your_boat_safer.
Here is another article by a blogger I suppose: https://gilwellbear.wordpress.com/2013/03/19/elci-a-primer/
Hopefully these links are OK with the TF Mods...
