New owners, blowing fuse at campsite?

[Abariterose]

It's finally here! Our 2009 Big Country 3490 BHS was delivered on 9-10-09 (this is our first fifth wheel). We love it, it is everything that we hoped it would be. But we have noticed that we keep tripping the fuse in at the site (have a 50 to 30 converter) when we run the AC, lights, and microwave. Through much trial and error, it was the microwave that keeps tripping the breaker (works fine with out AC running, not tripping the breaker). Is there something that we are doing wrong? Or do we have to just wait for the site that has the 50 hookup?

Trying to run high current motors simultaneously on a 30A breaker is the culprit. Until you can get a 50A site, you'll have to sacrifice the AC when you want to use the microwave. Unless you've got it switched to propane, your refridgerator is also pulling some of those 30A's for the compressor. When electric motors turn on, they actually draw more current than the rating plate says. This initial spike can be enough to trip the breaker if you already have some things running.

Are you running the water heater on electric? When on 30amps we find that to be the biggest culprit...if so, either switch over to propane, or when you want to use microwave switch it off until done. Water will stay hot for quite awhile...

Another appliance to run on LP would be the refrigerator. All good info from previous posters. The lights come off the converter and shouldn't cause much of a load. The A/C and Microwave will just about max out the 30amp breaker on startup.
