Keep in mind that these are approximate values and can vary depending on the specific refrigerator model and usage patterns.
Calculating Refrigerator Power Consumption in Amps
To calculate the number of amps your refrigerator draws, you can use the following formula:
Amps (A) = Watts (W) / Volts (V)
For example, if your refrigerator consumes 150 watts of power and operates at 120 volts, the calculation would be:
Amps (A) = 150 W / 120 V = 1.25 A
Refrigerator Circuit Requirements
When installing a new refrigerator or upgrading your electrical system, it’s essential to ensure the circuit can handle the appliance’s power requirements. A dedicated 20-amp circuit is recommended for most refrigerators, but this can vary depending on the specific model and local electrical codes.
Table: Refrigerator Circuit Requirements

| Small (100-150 W) | 100-150 W | 1.5-3 A | 15-amp circuit |
| Medium (150-200 W) | 150-200 W | 2-4 A | 20-amp circuit |
| Large (200-250 W) | 200-250 W | 3-5 A | 25-amp circuit |
Reducing Refrigerator Power Consumption
While refrigerators are essential appliances, there are ways to reduce their power consumption and lower your energy bills:
- Adjust temperature settings: Keep your refrigerator at a moderate temperature (around 37°F) to minimize power consumption.
- Use the energy-saving feature: Many modern refrigerators come with an energy-saving feature that can help reduce power consumption.
- Defrost regularly: Defrosting your refrigerator regularly can help improve its efficiency and reduce power consumption.
- Upgrade to an energy-efficient model: If your refrigerator is old or inefficient, consider upgrading to a newer, energy-efficient model.
