Consider the voltage. The second consideration is voltage, or the pressure under which current flows through an electrical system. While most U.S. appliances work at 110 volts, many foreign power companies generate electricity at 220 volts. Some appliances have a toggle switch that allows them to work with both voltages, but for non-dual voltage appliances, you'll need a converter to step down the 220 electric current to 110 so your appliances won't burn out.
A: To determine the proper size generator for your RV you need to know how much electrical power you will use. 1. Determine what electrical devices you will want to run from the generator. Survey your RV for appliances that run on 120 volts. TV, microwave and other kitchen appliances generally require the most power but smaller appliances can add up. Most RV lights are 12 volt but some may be 120 volt.
