That is very good. :thumbsup: It is also important to note that the GFCI only protects what is downstream or "load side" of the GFCI device. In a home this would be the GFCI outlet itself and any other outlets connected on the load side.

I my case the electrical compartment is on the trailer tongue and shore power plugs into this metal compartment. A/C wires then go underneath the trailer into the tail light area where I located my first GFCI. Only later did I realize that all the wiring in my tongue box and to the trailer tail was unprotected. :o I have recently installed another GFCI directly to the shore power inlet.

Good advice, Bill. It is always a good general rule of thumb to put the circuit protection device, be it a fuse or GFI, as close to the power supply as possible. This will cut down on overloading any of your wiring and avoid fire.

Another good GFI article. A bit more technical but worth a read by everyone.

It is not necessary for a GFCI to come with its own outlet. Home supply & electrical supply stores also sell a plain GFCI, which just contains the GFCI electronics, on/off switch and reset button. These are installed in the usual outlet boxes and protect everything wired "downstream" from them. I discovered them when I was wiring a GFCI circuit in my basement & just wanted a plain ol' GFCI switch on the ceiling where I would never plug anything into. I have found it difficult to test or reset a fully-plugged-in GFCI with outlets, and I have skinny fingers. Costs only slightly more than a GFCI combined with outlets. :designing:

This is a photo of one of those, mounted at the tail light compartment of my trailer. It protects the outlets in the galley and sleeping area but not the wiring in my tongue box where the converter and switches are located. More recently I added a GFCI there close to the shore power inlet. 8)

you might look at this it is worth reading if you do not understand electricity or think you do but have little experience with this monster.

DC no problem unless you get between a spark plug and the wire ZAPPPP! and it you are grounded oh the pain in my heart.
AC you've heard many a story depending on the voltage.

shows a survey and in the upper right are the chapters.

There are also GFCI cord ends available. This would protect everything downstream.

If your trailer has shore power ALWAYS install GFCI protection, and make sure you ground your trailer frame and all metal surface's. Aluminum skin can become energized by a fault condition and if it is not grounded and you are It may be too late when you find out!
