g f r & g f i problems.....for the well wired folks..

[2airishuman]

ok folks

these aren't contagious diseases....but they are a mystery....

i have a question for those who understand the inner juicey electical workings in modern airstreams...

i've searched here and not found an answer.......

twice while camping i ran into problems connecting my 05 classic to electricity....

on these 2 occasions as i would plug in.... the gfr/gfi would trip on the shore power side....on the power pole...not in the trailer.....

all power off inside the trailer...typical 30 amp plugs...
usually i connect the cord to the shore side first and then connect to the coach...
and at these 2 parks....the newly installed gfr on the shore side would trip...just by plugging in....

at one park they had a bank of brand new camping spots with brand new wiring....so after 4 hours of dinking around the electrician came out...and commented that the plugs needed to be rewired using "old code"...he did this on my site and solved the problem...i guess.

at the other site i finally used a 15 amp 2 prong adapter....with the ground post removed...and it worked.

can someone explain what my problem was/is....and how to avoid gfr/gfi issues going forward?

i've not had any other problems connecting anywhere...even with the 3 amp sort of daisy chains for rally....never had any circuits trip...all the appliances work fine...genset powers great...and so on.

05 classic, 30 amp, new marinco plugs/cord no unusual wiring mods (factory solar and gen set plug up front)and the usual assortment of dogbone and adapters...

cheer
