Calculating The Amps Used By A RV Refrigerator

Calculating The Amps Used By A RV Refrigerator

Calculating the exact number of amps used by an RV refrigerator can be tricky, but it is possible to make a rough estimate. This is important, as it will give you a better idea of your refrigerator’s power consumption and help you plan accordingly.

Here are the steps you should take to calculate refrigerator power consumption:

Determine the Type of Refrigerator

First, you’ll need to figure out what TYPE of refrigerator you have. Is it an absorption, compressor, gas-electric, or solar-powered model?

Knowing this will help you understand its power requirements and make your calculations more accurate.

Estimate the Typical Amp Usage

Once you know what type of refrigerator you have, look up its typical amp usage range ONLINE.

This will give you a good idea of how much electricity your refrigerator typically consumes so that you can calculate its average power consumption per day or hour.

Measure the Voltage and Amperage Output

Next, measure the voltage and amperage output from your refrigerator. This can be done with a MULTIMETER tool or an AMMETER, which are relatively inexpensive and easy to use.

Calculate the Amps Used

Once you have your voltage and amperage readings, you can calculate the amps used by your RV refrigerator by MULTIPLYING the voltage output by the amperage output.

For example, if your voltage is 120 volts and your amperage is five amps, your refrigerator uses 600 watts of power (120 x 5 = 600).

Alternatively, some refrigerators will list their wattage directly on their label so that you don’t need to do any calculations. However, this won’t give you an exact number of amps used since wattage is DIFFERENT than amps.

Monitor Usage Over Time

Finally, monitor your RV refrigerator’s usage over time to get a better idea of how much electricity it consumes and adjust your electric budget ACCORDINGLY.

This will help you ensure you don’t exceed your allotted electricity usage for the month. It can also help you identify potential problems with your RV fridge if its consumption suddenly changes drastically.
