Most likely, it will.....but can depend on a few factors.
Your converter (which I sent an explanation in a private message the other day) should now be operating. We have discussed the point that the non-working leg of your 50 amp power supply was probably the same leg that was used to power the converter..........or since this leg wasn't working, neither was the converter.
Remember that the converter is what converts 120 volt electricity to 12 volt....to provide power to the things in your RV that require 12 volt to run. Your converter also has a battery recharger function too. The brand/model of your converter will dictate to how well it can recharge a battery....as well as how depleted the battery is to begin with.
Now that you are using a 30/50 adapter as joenic53 originally suggested........you don't have a missing leg that you did from your faulty pedestal 50 amp supply (which you remember is actually 2(two) 120 volt legs at 50 amp a piece when working correctly). Your RV is setup so that it takes these two 120 volt legs and uses one leg to power certain things and the other leg to power other things.
The adapter you just obtained, will now take the one 120 volt leg from the 30 amp outlet at the pedestal......and share it across both sides inside your trailer. Everything in your trailer is now being powered from that one 120 volt 30 amp leg now. That's why you can only run up to 30 amps worth of things when using this adapter.
The good thing is, your converter should now be powered this way and should be working to power the 12 volt things in your RV as well as recharging the battery..............albeit you are just limited in what all you can run at the same time. It works better than the alternative right now....which was only about half of your stuff working. Now, everything will work, just not all at the same time.
30 amps usually won't run two air-conditioners, but will power one.
Once you get the electrician to fix the faulty 50 amp pedestal.....you will be good to go sans the adapter.
Mark Polk has a great article on converters which is explained here:
