Fried electrical

Help!  I received bad advice and wired my 30amp plug with two hots and one ground.  When I plugged it in the GFI tripped on the electrical plug in the power bay under the motorhome.  I have since wired a new plug using the 50amp cord.  Output power is correct with two hots, one neutral and one ground.  I have absolutely  no power in motorhome.  Generator causes the power switch to trip the contact points.  Still no power in motorhome.  Shore power I have to push the switch in.  Still no power at the circuit breaker panel.  I have checked all the GFI plugs that I can find.  When 50 amp cord is plugged into the receptacle on the motorhome I need to physically push it in and hold it for the power to get to the power switch.  I have the correct power on front end of contacts.  I have the correct power on the back end when I push in the switch.  Still now power to the circuit breaker panel in the bedroom of the coach.   The coach is a 1994 Safari.  In the power bay I have a power switch that has the generator, inverter, and shore power in.  It is also hooked up to a power surge box.  There is a GFI plug in the bay with a large plug plugged into it.  Inverter will now even power the television.  The inverter hums like it is working.  I believe I need at least a new power switch box (two contact points, and two circuit boards in the box), I don't know if I fried the power surge box.  I will have to look at the receptacle where the shore power hooks into the motorhome (probably some issues there).  Any idea why no power to the circuit breaker.  Is there another fuse, relay, or circuit breaker between power switch box and circuit breaker panel?  Any help would be greatly appreciated.

May have fried your automatic transfer switch. It switches power from shore or generator and all power goes through it. Onboard GFCI will not usually effect shore power.

What exactly are you trying to accomplish here, simply replace a cord and plugs?? You stated you had mis-wired your 30 amp plug

You mentioned using a 50 amp cord and plugs?? Are you using a 50 amp source (your description sounds like it). Are you sure you have a motorhome that is wired for 50amps?? I don't remember that as being widely used around the year 1994 .

Not familiar with a 94 but start with this site here: http://www.myrv.us/electric/
check your 30a (& 50a if you have that) wiring plug(s) to make sure it is correct. Once you know you have correct shore power then see if you have an auto transfer switch as that will be next in line before the MH breaker panel. Once you get power to the panel then you can start tracing what works & don't work in the MH depending on what you have.

I suspect he fried more than his cord. He likely did in such diverse things as televisions, microwave, converter, and possibly the electric elements on the water heater and fridge.. If he had an Air conditioner operating it may have fried as well.

This is why I recommend folks install a 50 amp outlet for an RV (Even if they only use 30 amp breakers) and use the proper adapter.. This completly avoids this kind of OPPS.
