Dual 30 amp rv's?

Was doing some "window" shopping on Camping World site, and saw a dogbone for dual 30 amp to a single 50 amp receptacle. Are there actually RV's that have 2 30 amp hookups??

  • Hi,

    I think that what you saw was a pair of 30 amp plugs going into a 50 amp receptacle. While it might work in some situations, modern RV parks use GFI receptacles, and will not work with that adapter.

    You might find a few RV parks with a pair of 30 amp receptacles at a RV site, however it would be a 'pair' of campsites sharing a single power post, with two 30 amp plugs - 1 for each RV. SO if the neighbor's site is filled, they will use on, and you will only be able to use one of the plugs, and not this adapter.

    Any 20 amp GFI that you plug this adapter into will trip, because all of the power going out on the 'hot' line is not returning on the 'neutral' line.

    At first I was thinking that you saw a used RV with twin power cords. While that is possible, the past owner might have installed 'anything' - but RIVA will not allow two power cords on one RV, so it was not installed at the factory that way.

    Good luck!

    Fred.
  • OK, smkettners post likely described the adapter you saw. I was thinking of a different adapter.
  • Some have installed a second circuit for more power. The adapter you saw will allow a 50A RV to plug into two 30A plugs or 30A and 20A which provides more power than a 30/50 adapter.

    There are many posts on this subject. While it can be useful there are pitfalls that can occur. Best to avoid this adapter.
  • Nah, that is for two 30a RVs to share a 50 amp connection.

    As described with a 50 amp receptacle it would be to run a 50 amp RV from two 30 amp supply outlets.
