45amp dogbone adapter

I'm interested in knowing  if it is worth having a 30 amp / 15 amp dogbone adapter in case I find myself in a location that has 30amp and a 15 amp (non gfi) outlet on the pedestal. In order to get the two hot legs to the coach.

Or should I just stick with 30amp and avoid any potential issues.

Any thoughts, good or bad experience with this set up.

Always have a 30/15 adapter and a 100" rigid 10 gauge  extension cord. 

I have both a Rigid  10 gauge and a 12 gauge 100' extension cord.  And two 30/15's and the now illegal 30/20 amp input cord dual input.  You never know.............

You will find that now days not too many non-GFI 15a plugs on rv hook ups. Also the 30 and 15 have to be on different phases. In short not worth it.

A 100 ft 10ga 3 conductor heavy duty extension cord is rated at 20 amps for safety and voltage drop reasons.  Use one of these with 30 or 45 amps at your own risk.

Thanks for the info - I might just pass for now on getting one - but I appreciate the info on the extension cord gauge/amps/length.

I have one of the earlier Progressive Industries square box adapters.  Yes, most campgrounds have gfci's so it's not useable many places.  But I've used it successfully recently at a few campgrounds and it is nice to have the extra 15-20 amps.

I am able to use two gfci campground 30 amp receptacles (or 30amp + 15amp) simultaneously because I ran a second neutral wire to the service bay and installed two 30 amp twist lock receptacles in the service bay. I seldom visit campgrounds with 50 amp (really 100 amp) service, so seldom use the 50 amp power cord.

To facilitate using two campground gfci receptacles required rewiring the main power panel in my Foretravel such that the neutral wires from each of the two 50 amp main breakers are connected to separate neutral bars. These two neutral bars are each connected to one of the 30 amp twist lock receptacles in the service bay. A switch on the front of the main power panel allows connecting the two neutral bars together when using the 50 amp power cord.

I carried one for 8 plus years, used it once, and gave it away.  The pedestal is usually rated for and wired for 30 amp max, with two breakers/receptacles of 30 and 15 amp.  Still only 30 amp capable wiring....

Have one. Never used in 5 years. 15 amp always gfi, and that is a show stopper
