RVs typically connect to 30-amp or 50-amp service check your RV’s plug.
To determine if your RV is 30 or 50 amp, you can check the electrical service panel or the power inlet on your RV. Open the electrical service panel, usually located in the main living area, and look at the main breaker; a 30-amp RV will have a 30-amp breaker, while a 50-amp RV will have a 50-amp breaker. You can also examine the power inlet where you connect to shore power; a 30-amp inlet is smaller and has three prongs (one hot, one neutral, one ground), while a 50-amp inlet is larger and has four prongs (two hot, one neutral, one ground). Another method is to calculate the total wattage of your appliances; if the sum is less than 3,600 watts (30 amps × 120 volts), it is likely a 30-amp RV, whereas a total over 3,600 watts (up to 7,200 watts) suggests a 50-amp RV. Additionally, if your RV has two or more air conditioning units, it is typically a 50-amp model, as 30-amp RVs usually can only run one AC unit at a time.
