So how could/do you camp somewhere without shore power? It would make it awful tough to boondock, if you need shore power just to move the slides.

BTW - When we were looking at TT's (to purchase) a few years ago, it was between Thanksgiving and end of year, so most units in the dealerships outside lots had already been winterized, with slides closed. In more than one dealership, since they don't leave batteries in the units on the lot, the salesmen carried those small 12v jumper boxes, designed to give a car a quick jump start. This is what they used to move the slide in and out and "show" the unit without a battery or shore power.

Fire Guy, I think you missed his point. It is not shore power that has to be connected but the battery. That "jumper box" takes the place of the battery. I am sure it is plugged in between demos, since it has to pull that baby flat opening and closing the slides. The AH rating has to be no more than 5 or 10. (100 - 200 total amps available). At that high a discharge rate compared to AH rating, the true capacity may only be 50% of rated.

I move my slide without the battery all the time. No issues.

Herk, welcome back!

I've got a stupid question. My WFCO puts out 55 amps and I believe my slide motor is a 30amp. While moving the slideout, if I were also running other items in the trailer (AC, lights, etc) that would draw more current than the WFCO can provide to all of these items, then wouldn't it just pup a fuse or circuit breaker?

Are we talking about with the battery removed? If so, I guess it would depend on how the total load on the DC side is protected (unknown since it would be internal to the WFCO) and there is no circuit diagram provided.

There are two 40 amp reverse current fuses (so that is not the protection); it is on the same 120 VAC circuit breaker (in my camper) as the living room and kitchen GFCI circuits (so that is not the protection); and the 12 VDC fuses are all 15 amp in the box (so that is not the protection) and there are two 30 amp Slide fuses and a 30 amp landing gear fuse hung off the battery buss (at the battery), so THOSE are not the 55 amp protection.

Since 12VDC x 55 amps is 660 watts, we are only talking about 5.5 amps AC at full DC draw. This is well UNDER the 15 amp 120 VAC circuit breaker it is hooked to.

Long and the short of it? I don't know if there IS any overload protection for the 55 amp DC side other than overheating or component failure without a circuit diagram.

This is good. I pulled up the installation manual and the wiring diagram is not clear (at least to me). I attached it in case anyone is interested.

Interestingly, when I read through it, I found a general feature notation that states "...Automatically shuts down power during overload or short-circuit conditions.
Automatically returns to normal operation after conditions are corrected."
It didn't go into details, however.

We have a 7000 watt generator!

And where I live there isn't any parks that don't have power.
We boondock with friends twice a year in a big private timber and we all have gennies.

Thanks for adding that. I was looking at the "diagrams" not the text when I added my comments. The manual has "hook up" drawings and not actual circuit board schematics.
