T&T: GFCI problems

inverters can be configured at least two ways. One is for neutral and
ground to  be tied together, the other for them to be separated. The
inverters come from the factory with ground and neutral tied together,
this automatically trips the  shore power GFCI. I have an Interphase
inverter. It has a screw that can go into one of two holes. In one hole
the ground and neutral are tied together, in the other hole they are
not. By going to the hole where they are not tied together, the problem
with tripping the GFCI was eliminated. Every boat  that had the tripping
problem and had electricians come to fix the problem ended up with a

That is the difference with "marine" and RV designated inverters. 
Unfortunately if you simply disconnect the green connection d oyou make
sure the green safety wire is properly connected to the vessel
grounding/bonding  system?   Improperly  done you simply create a shock
hazard.
