    <font face='Arial'> So, I got myself nice and sweaty this morning installing my 13.5K Carrier a/c on my 08 Flagstaff PUP--by myself! Not bad for a lawyer who's never done anything like that before...

    Problem is that I've searched and searched and cannot find any info on how the a/c wiring is routed inside the camper and to shore power (or not).

    I have an extra "out" hole next to my shore power---should I just add an end to the 12ga. romex and plug in at the campground (haven't been anywhere yet--but that will change now with a/c!)? Are there 2 plugs at most campgrounds for "normal" shore power line and a/c? Can I just plug it in inside the PUP into one of the outlets? I did, and it seems to work fine, but d/n want a fire at 2am! Electricity is really not my thing...

    My power inverter reflects a 15a and 20 breaker--and 2 outlets inside the camper. Which is which???? (one is GFI protected).

    Last, anyone have pics of how they've wired the power to the roof internally? That Romex is pretty stiff stuff--what do you do with it when folding down?

    Thanks much,
    John

    ps--I have read ALL the manuals that came with my PUP, to no avail.</font id='Arial'>

    I may disagree with what you say but will defend to my death your right to say it.

    Well....

    Here is how we did ours,


    Fleetwood does all of theres using a kit like this

    <img src="http://www.buyastrostuff.com/ftp/Rays/camper/AC%20Kit.jpg" border=0>

    They use surface mount conduit to hide their wiring where exposed. Myself, I did not like the look. So I made a wood panel to reinforce the roof between the two roof supports and hide the wire underneath it. I then ran the wire thru the metal support to the side of the roof.

    I then used surface mount conduit at that point to run the wire to the right rear corner. At that point I let the cable hang with the curtain.

    The end of the cable plugs in to the 20 amp receptacle in the right rear corner of the pup..

    Any way, That is how I did mine...

    Hope it helps...

    Thank you--very helpful. Mine has no conduit/bracing. It looks like you used what I would call heavy-duty "extension" cord--which is a heck of a lot more flexible than traditional Romex.

    How do you know which outlet is 20a?

    Thanks again-John

    Hi,

    The 15A breaker should be the one that goes to your GFI outlet that then daisy-chains to the other outlets.

    The 20A breaker is there for an air conditioner. It should run around and to one corner to a box with a blank plate. This is wired up so you can put an outlet in and run your AC power cord over the ceiling and then down to the outlet.

    Although it does not meet electrical code, I would run heavy duty extension cord through a piece of plastic 'cable duct' from the unit to the side wall; leaving a 'pig tail' of 4' or so to pull into the outlet.

    On ours, the 20 amp plug is the only white one. The other 3 outlets are all brown and GFIC'd. The white one is also on a separate 20 amp breaker and all the others are on a 15 amp. Other that that the plugs look the same.

    On the cord, Yeap I got a 12 GA extension cord and wired it in. It is the same as Fleetwoods but a different color.

    I just could not bring myself to buying their kit at $110. It cost me less than $30 to put together the same parts in my own kit. The kit for a E3 consisted of one cord 20 feet long, 4 - 1x1x1/16th aluminum angle and some misc hardware. It would have been different if it included a brace, but the E3 comes with 2 braces from the factory.

    the factory set up for you flagstaff is that the cord from the a/c on the roof connects to a male end that is embedded in the side of the roof and is covered by a outlet like the one on the side of your pup. then the power cord comes out of the second outlet next to the regular power cord outlet and routes up to the outlet in the roof. so to sum it up, you have a regular shore power cord and then a second one that comes out of the bottom second opening and is routed up to the outlet on the roof for the a/c and of course it is on its own seperate circuit. now having said all that i would run the cord down along one of the walls and put in a outlet that was dedicated just for the a/c and then route a seperate out the existing second hole and plug it into the 30 amp outlet on the power pole of the campground, what you could do is get an adaptor for the regular power cord so you can plug it into the 20 amp outlet and save the 30 amp outlet for the a/c cord
    hope this makes sense..
