Can a refrigerator and microwave be on the same circuit?

Yes, a refrigerator and microwave can technically be on the same circuit, but it is not recommended. Both appliances draw significant power, particularly when they start up. The refrigerator typically requires a steady current, and when a microwave is also running on the same circuit, it may lead to excessive electrical load, potentially tripping the circuit breaker.

Combining these two high-demand appliances on a single circuit can expose your electrical system to unnecessary strain. To ensure optimal performance and safety, it is advisable to have separate circuits for each appliance.

What are the risks of putting a refrigerator and microwave on the same circuit?

The primary risk of placing a refrigerator and microwave on the same circuit is the potential for overloading the circuit, which can result in tripped breakers. This situation can cause inconvenient interruptions in power, particularly in kitchens that rely on both appliances frequently. When the microwave is used, it can momentarily draw more power than usual, causing the refrigerator to cycle off, which may affect its cooling efficiency.

Moreover, the risk extends beyond mere inconvenience. Continuous overloading can lead to electrical hazards, including overheating wires or components. Such risks can potentially result in damage to your appliances or even lead to electrical fires if not managed properly.

What is the recommended circuit size for a refrigerator and microwave?

According to the National Electrical Code (NEC), a refrigerator typically requires a 15 to 20-amp dedicated circuit. This ensures that the refrigerator has sufficient power to operate efficiently without any interruptions. In contrast, a microwave usually needs a similar 15 to 20-amp circuit, depending on its wattage and design.

To avoid complications, it is wise to have dedicated circuits for both appliances, ideally rated at 20 amps, especially for high-wattage microwaves. This approach not only assists in managing power loads but also adheres to safety regulations outlined in the NEC.
