The temperature settings on your refrigerator can also affect its amperage draw. For example, setting your refrigerator to a much colder temperature than necessary may cause it to work harder, thus increasing the amperage.
Calculating Energy Consumption
Understanding the amperage of your refrigerator can aid in calculating its energy consumption and costs.
Basic Formula for Energy Consumption
The basic formula for calculating energy consumption is:
Energy (in kilowatt-hours) = (Voltage x Amperage x Time) / 1000
Most household outlets provide 120 volts in North America. Using this formula can help you get a clearer picture of energy costs.
Example Calculation
If you have a refrigerator that draws 10 amps and runs continuously:
- Voltage = 120 volts
- Amperage = 10 amps
- Time = 24 hours
Energy consumption can be calculated as follows:
Energy = (120 volts x 10 amps x 24 hours) / 1000 = 28.8 kWh
You can multiply this by your local electricity rate to estimate your monthly costs.
Understanding Starting and Running Amperage
When discussing refrigerator amperage, it’s essential to distinguish between starting and running amperage.
Running Amperage
Running amperage refers to the amount of current the refrigerator uses during its normal operation. As noted earlier, this is typically around 5-15 amps for most refrigerators.
Starting Amperage
Starting amperage, or “inrush current,” is the initial surge of current that occurs when the refrigerator’s compressor kicks on. This value can be substantially higher than the running amperage—sometimes up to 2-3 times greater.
Understanding both types of amperage is important for:
- Electrical System Planning: Ensuring that your home’s electrical system can handle the peak load.
- Avoiding Circuit Breaker Trips: Safeguarding against unexpected interruptions in power.
Finding Your Refrigerator’s Amperage Rating
Now that you understand the importance of amperage, you may be wondering how to find the specific amp rating for your refrigerator. Here’s how to locate this vital piece of information:
Check the User Manual
The user manual that comes with your refrigerator usually includes a section on specifications, which will contain the amperage rating.
