A common motor home generator runs on diesel fuel. The driver attaches electrical appliances, such as inside lighting or a refrigerator, to the generator to provide power. The generator negates the need to use the motor home's engine battery as a power source, which can drain the battery over time.
A motor home diesel generator produces 120 volts or a combination of 120 volts and 240 volts. The 120-volt output reflects a basic home electrical outlet voltage; this is used for everyday small appliances. The 240-volt option allows attachment of large electrical appliances, such as two separate air conditioners, with a safe 120-volt level for each item.
Verify the wattage and voltage levels when purchasing a motor home diesel generator. Wattage levels vary among generators, but the voltage output is constant. Larger electrical appliances, especially air-conditioning units, use more watts.
