A friend looking for a rv

Ok, Electricity, an important point, RV should be used in Europe and also in North America.

If I understand you right then all appliances in the RV works from 12V, some direct, some over an Inverter 12>110V. Right?
I never need shore power if the Batteries have full power?

My ideas go the way to install a powerfull charger 240/50 > 12V for European use.

To change al the appliances like, Microwave, Fridge and others could be difficult because of the measurements, Europa has a different standard size kitchen, 60cm wide machines.



B&W hitch is noted.

No, the appliances (microwave, TV, washer/dryer, residential fridge, etc.) operate on 120VAC. An RV fridge and an RV water heater can operate off of 120VAC or propane; the controls operate on 12VDC. Most lights (other than plug-in lamps) operate on 12VDC.

Here is a link that might help you understand the electrical system on a typical RV.

Rusty some of the lower cost RV around the 50K mark wire up all of the electrical appliances and outlets to just one side of the power distribution center say L1. The other leg is for the second AC in the bedroom that could be added later by the end user. I know that my unit is wired this way and the owner’s manual stays this in the instruction for the RV electrical system. They claim that you can therefore use the 30 AMP circuit breakers in the campground with an adapter plug for the 50 AMP power cord.

An RV doesn't have to be wired that way to use a 30 to 50 adapter. The 30 to 50 adapter powers BOTH buses in the 120/240VAC 50 amp RV's power distribution center. It does this by tieing the L1 and L2 leads of the 50 amp shore power cord together in the adapter. If you don't believe me, take an ohmmeter and ring out your 30 to 50 adapter. You'll find the single hot pole on the 30 amp side is connected to both hot leads on the 50 amp side. Here's a LINK to the info below if you want another source.

30-50 amp Dog Bone Adapter

We generally refer to some of these adapters as dog bones because the plug and receptacle at each end of a short piece of cable looks a little like a dog bone. Also instead of the long 50 amp Male to 30 amp Female description, we use a shorten format of the male amps first followed by the females amps.

In a 30-50amp adapter, the plug has two flat blades and the round prong. The Hot wire is used to attached to both Hot wires in the Adapter receptacle end along with the Neutral and the Ground.

This Adapter allows 50 amp style connections to a 30 amp power pole receptacle. Caution should be used because the 50 amp style connection could expect 100 amps of power (50 amps on each leg) and the outlet can only deliver 30 amps for both legs. The power pole breaker will protect the outlet.

The is probably the most used Adapter when 50 amp RVs visit older RV parks that have only 30 amp service.
