if you are tripping the breaker running what the manufacturer has put on the rig, i think you have an Internal problem.

Actually, on RV's with a 30 amp service, you have to practice energy conservation to a point. You can hardly ever run everything that is installed at the factory at the same time. especially if you have an installed air-conditioner.

These links below will help explain that.

so, you really can't run the AC and the HW at the same time with the coffee pot. Boy, i wish the dealer would have mentioned that when we were looking at our unit.

The AC can draw up to 28 amps on startup (fan and compressor starting at the same time) and drops back to about 15 amps running.
The heating element is 1000 watts of AC or 9 amps at 110 volts.

The DW's hair dryer has been the cause of tripped breakers and fire alarms.

She now has a MUCH smaller unit (still 1000 watts though) that is only used in the camper.

Here is a chart with approximations of common use items in a travel trailer, along with OE installed equipment draws. You also have to understand that even though you are limited to basically 30 amps of TOTAL draw, you also have individual circuits inside the trailer that are limited to less than this, say 15 amps or so. You can see this in your breaker box. If you overload these individual circuits, they will also trip. So you have to not overload each individual circuit, nor let the total of the individual circuits added together to overload the main 30 amp breaker.

Here is a chart with average amp draws for common items:


120 Volt AC Amp Ratings
Appliance or Electronic Equipment Estimated Amps
Air Conditioner (X number of A/C) 12-16 Amps
Blender 5-6 Amps
Coffee Maker 5-8 Amps
Compact Disc Player 1 Amp
Computer (Laptop) 2-3 Amps
Converter 1-8 Amps
Crock Pot 1-2 Amps
Curling Iron <1 Amp
Drill 2-6 Amps
Electric Blanket 0.5-1.5 Amps
Electric Fan 1 Amp
Electric Water Heater 9-13 Amps
Electric Skillet 6-12 Amps
Hair Dryer 5-12 Amps
Iron 5-10 Amps
Light (60 watt % 120V) <1 Amp
Microwave 8-13 Amps
Microwave (Convection Oven) 13 Amps
Refrigerator in AC mode 5-8 Amps
Space Heater 8-13 Amps
Television 1.5-4 Amps
Toaster 7-10 Amps
Vacuum (handheld) 2-6 Amps
VCR 1-2 Amps
Washer/Dryer 14-16Amps

I have the same problem when I use my hair dryer. Oh, wait a minute, I use a towel.

If you are having this problem, then you can turn off the water heater's electric heating element (if so equipped), and run the water heater off propane, thus saving these amps for something else.

I've seen some trailers that have the microwave and the water heaters electrical heating element on the same circuit, which always trips when you have both on at the same time.

You'll get the hang of it in time, and realize what has to be turned off so something else can be turned on.

A good mindset is to always remember that anything that makes heat or cools is going to use the most electricity.
