Convert 30 amp to 50 amp

Bought our 1st Class A two weeks ago, having a blast finding out all about her. '94 Fleetwood Southwind, I would like the ability to run both roof a/c's at the same time, is there a "fix" or a way to change over to 50-amp. Existing schematics would be helpful if it is possible. I would like to thank all of you "pros" that have taken the time to respond to what I'm certain are my elementary and oft posed questions, CBS <><

Converting and rewiring the whole coach would be a job for a professional unless you really understand how 50 amps are delivered to the power panel. You might think about a second cable, 30 amps, that just plugs in and powers rear A/C. That could be wired rather easily with a box and circuit breaker. Use a pigtail that converts 30 amps to fit the 50 amp outlet. Then your second cord would plug into the 30 amp outlet. Most all 50 amp pedestals also have 30 amps, although many campgrounds don't allow both outlets to be used.

Did the coach come with two A/C units and 30 amp service? If so, is there a management system that handles the two A/C units, sheds power as needed, etc.?

This how my 2002 Fleetwood Pace Arrow with 30 amp service works.

Hey Guitar Lefty, here's a link to how I did it on a Mirada that we owned, not sure if yours is set up the same way, but take a look it may solve your problem.

Great, I'm checking to see if the second line for the rear a/c unit can be tied with the coach power supply and 1) 50-amp pigtail connecting to the park hookup, thanks

I changed my Journey over. Was not a very difficult job, however I am a retired electrician. Things that may need to be changes is transfer switch, distribution panel ( breaker Panel ), main power cord and a lot of wiring. Will also need a good set of wiring diagrams. Was worth it for me to be able to run everything at the same time.

It is not too hard to do if you have some electrical knowledge. But, if you are not electrically inclined, I would look to a professional fro help.

Not all campsites are 50 amp capable.. The first suggestion (The link to the other article) is a good idea even if you covert to 50 amps.

I live in a 50 amp Class A.. I did something very muck like that article "Broke out" the 2nd A/C to a plug and outelt) and often run it on it's own Independent 20 amp 12ga extension cord isolating it from the rest of the RV. Works great.

However a full 50 amp conversion has additional benefits.. But I'd still do the break out box.
