The typical RV has either a 30-Amp or a 50-Amp Service.
This can really limit you at times when you are camping and using a lot of your appliances. The result of this will usually be a thrown breaker, either in the Camper, or at your campsite service box.
In order to avoid such a dilemma, you should be aware of how much current your appliances can draw and plan your day avoiding using too many electrical devices at one time.
The table below lists the typical current used by must standard 110-VAC appliances.
Air Conditioner (Startup Current)- 12.5 Amps
Coffee Pot, Electric- 9 Amps
Crock Pot– 1 to 2 AMps
Food Processor– 8 to 10 Amps
Frying Pan (Electric)- 8 to 10 Amps
Hair Dryer– 10 to 15 Amps
Iron– 10 Amps
Oven, Microwave– 10 Amps
Refrigerator (2-door medium)- 2 to 4 Amps
Toaster– 8 to 10 Amps
Vacuum (Dirt Devil Hand Unit)- 2 Amps
Water Heater, Electric (6-Gallon)- 8 to 12 Amps
These numbers are average numbers and vary by type of appliance, but you can see how they can add up and you can exceed your breakers current capacity if you are not very careful.
NOTE: Typically, the lights in your Camper are 12-VDC and operate on your RV’s 12-Volt batteries. But, remember, that at times, if your batteries drop below a certain limit of stored charge, your AC/DC Converter/Inverter will kick in and can draw some significant current as it charges your batteries back to their normal level.
