This means if you have a 20-amp circuit, the total continuous load should not exceed 16 amps (80% of 20 amps).
Assessing Circuit Capacity
To assess whether your circuit can handle both appliances, you need to know the circuit’s ampacity and the appliances’ power requirements in amps. For example, if your fridge and washing machine together consume 650 watts at 120 volts, their total current draw would be approximately 5.42 amps (650 watts / 120 volts). If your circuit is rated for 20 amps and you’re considering other appliances that might be on the same circuit, you need to ensure that the total load, including these other appliances, does not exceed 16 amps (80% of 20 amps).
Importance of Dedicated Circuits
For high-power appliances like washing machines, dedicated circuits are often recommended. A dedicated circuit is one that serves only one appliance, ensuring that the full capacity of the circuit is available to that appliance. This approach minimizes the risk of overloading and provides a safer and more reliable operation. While it might be technically possible to put a fridge and a washing machine on the same circuit, especially if they are used at different times, the safest and most efficient approach is to provide each with its own dedicated circuit, especially if local codes and the specific electrical setup of your home allow for it.
Conclusion and Recommendations
