Home again

[gregory O]

the condition is called lost neutral or open neutral. to call it a common would
imply dc current. I believe???the transfer switch removes the neutral along
with the two hot lines otherwise the shorepower neutral which is earth ground
will ground out all the genset ac current???. if the transfer switch was the
problem that caused the other resulting issues, replacing the resulting issues
and the causing problem (transfer switch) will keep it from happening again. it
may well be that the neutral was lost some other place like in your shore cord
or in the campground pedistal and the issue is doomed to repeat its self again.

I can not understand how the ac current transfers voltage to the other leg when
the neutral is lost but I realize that electrical code properly followed will
prevent the damage.
Here is a rv related lost neutral article
http://www.myrv.us/electric/Pg/open_neutral.htm

One of the gals in our rv club had a recent lost neutral when her plug fell out
of the reseptical on an angle. the ground and center two hot prongs stayed
connected. I can also see where carbon stained prongs on the plug can cause a
lost neutral. I now always make the effort to shut down the breaker prior to
connecting and use duct tape or a copper wire tie (10 ga single strand
irrigation wire)to keep the pedistal connection inplace
