Converting to 50 amp

How hard would it be to convert a 30 amp 5ver (or TT for that matter) to 50 amp? Has anyone ever done it?
  • Very easy to do, I did ours when we added a 2nd A/C. One way to do it is to add a new panel connected to the 50 amp line and feed the original 30 amp panel from one side as a sub panel and connect 2nd A/C and whatever else to the other side. That is the simplest way and not that expensive. Works for me. :)

    If you're looking to add a 2nd A/C, from what I've read here, it may be easier to simply add a small panel with a second, 20a external plug for the pedestal.

  • If all the words in the idea of "two 50 amp circuits running 180 degrees out of phase with a common neutral" are fully understood, it is just a matter of finding space and changing shore power cords.

    Try to keep the loads balanced.

    Good Luck!
  • You can gain a lot by adding a small panel with a few 20A breakers and splitting the 2nd AC off. Add an extra recep somewhere.

    An alternative is to add a new 50A panel and cord. A 30A CB feeds the existing panel which is now a subpanel. Rewire any current or new circuits to the new panel as desired.


    yep, shouldn't be too involved other than finding space, places to run wires, etc. shouldn't need to be a nuclear surgeon or brain scientist to do it.

  • Never done it, but have read where it has been done. If your not good with electrical just have it done. You can do it probably a weekend job. Depends how deep you have to did in your Rv to find everything. You will have to replace the electrical panel, shore power cord, some of the existing wiring, and if thinking about installing a second Ac then getting the wire to the roof. Good luck if you do and keep us posted on the mod.
