Did You Know?
1. Did you know that the average microwave requires a breaker size of 15-20 amps? However, it’s always important to check the manufacturer’s specifications to ensure you’re using the correct breaker size for your specific model.
2. In the early days of microwave ovens, they were often referred to as “radar ranges” due to their use of radar technology to generate heat and cook food.
3. Contrary to popular belief, microwaves do not cook food from the inside out. They actually heat food by producing electromagnetic waves that excite water molecules, stimulating heat throughout the entire dish.
4. The concept of microwave cooking was accidentally discovered by an engineer named Percy Spencer in 1945. While conducting experiments with a magnetron tube, he noticed that a chocolate bar in his pocket had melted. This led to the development of the first microwave oven.
5. The Soviet Union was the first country to put microwave ovens on the market for household use in 1957. However, they were initially quite expensive and weighed over 300 kilograms, making them impractical for most households at the time.
Smaller Microwaves And Regular Outlets
When it comes to smaller microwaves, the good news is that they can be conveniently plugged into a regular outlet. These microwaves require a smaller circuit breaker due to their lower power consumption. Most small microwaves use a standard 120-volt circuit and typically require a 10 amp circuit.
It’s important to note, however, that amp requirements may vary between 15-20 amps depending on the specific model and manufacturer.
While smaller microwaves do not require a dedicated circuit, it is crucial to ensure that the circuit they are connected to can handle their power demand. This can be verified by checking the amp rating provided on the label of the microwave. Ignoring this vital step can potentially strain the wiring, leading to safety hazards and potential damage to both the microwave and electrical system.
Microwaves Above The Oven: 20 Amp/240-Volt Circuit Breaker
Microwaves installed above the oven have specific requirements that need to be considered. They require a 20 amp/240-volt circuit breaker due to their higher power demands and increased voltage. This ensures safe and optimal operation of these larger microwaves.
Installing a microwave with higher power requirements on a circuit breaker that is not designed for it can lead to frequent breaker tripping, potential damage to the microwave, and electrical hazards. It is important to follow the recommended circuit breaker specifications provided by the manufacturer for microwaves installed above the oven.
- Key points:
- Microwaves installed above the oven require a 20 amp/240-volt circuit breaker.
- Following the manufacturer’s recommendations ensures safe operation.
- Improper installation may cause frequent breaker tripping, microwave damage, and electrical hazards.
Microwaves installed above the oven have specific power requirements. It is crucial to follow the recommended circuit breaker specifications to avoid potential hazards and ensure proper functioning.
Amp Requirements For Small Microwaves
Most small microwaves operate on a 120-volt circuit with an amp requirement between 10 and 20 amps. The amp rating provided on the microwave’s label is the best reference for determining the appropriate breaker size. It is essential to take into account the constant load and spike issues that microwaves can generate.
Microwaves within this range generally have a manageable power consumption that can be adequately handled by the standard 15 or 20 amp circuit found in most homes. However, it is always wise to double-check the specific requirements of the microwave being used to ensure it does not exceed the capabilities of the circuit breaker.

Recognizing The Need For A 20 Amp Circuit
Microwaves in some cases, may require a 20 amp circuit to meet their power demands adequately. These cases can be identified by the presence of double prongs in the circuit breaker box. The National Electric Codes (NEC) prohibits sharing circuits between microwave ovens and refrigerators due to different power requirements. Therefore, it is essential to have a dedicated 20 amp circuit to ensure the safe and efficient operation of these microwaves.
Choosing a dedicated 20 amp circuit for a microwave is essential due to their constant load and spike issues. By providing an adequate power supply, the risk of breaker tripping and electrical damage can be minimized. It is crucial to consult with a qualified electrician to determine the correct circuit requirements for your specific microwave model.

Importance Of Choosing The Right Size Breaker
Choosing the right size circuit breaker for a microwave is crucial for optimal performance and safety. While wattage rating is often used to determine breaker size, it is not the sole factor. The amp rating provided by the manufacturer is the most reliable reference for selecting an appropriate breaker.
Ignoring the recommended breaker size can strain the electrical system and pose a fire hazard. Therefore, it is essential to calculate the maximum wattage capacity of the circuit before connecting the microwave, ensuring it does not exceed the breaker’s capabilities.
selecting the appropriate size breaker is a critical step in ensuring the microwave’s optimal performance while prioritizing safety. Here are a few guidelines:
- Smaller microwaves generally operate on a 120-volt circuit and require a 10 to 20 amp breaker.
- Larger microwaves installed above the oven may require a 20 amp/240-volt circuit breaker.
Remember to always verify the manufacturer’s recommendations and consult a qualified electrician to ensure compliance with safety guidelines and prevent potential issues with the electrical system.

Frequently Asked Questions
Does a microwave need a 15 or 20 amp circuit?
A microwave typically requires a 20-amp circuit due to the constant load and potential spikes in current that it can generate. The extra amperage provides a buffer to handle the demands of the microwave, especially when it is operating at maximum capacity for extended periods. While a 15-amp circuit may be sufficient for some smaller microwaves, a 20-amp circuit ensures a safer and more reliable power supply for larger or more powerful models.
Can you put a microwave on a 30 amp breaker?
Yes, it is generally possible to put a microwave on a 30-amp breaker. Since a 30-amp circuit provides 3,600 watts of power, it can accommodate the energy demand of most microwaves. However, it is important to check the specific power requirements of the microwave you intend to use to ensure it does not exceed the available wattage. Generally, smaller microwaves should be compatible with a 30-amp breaker, but larger or more powerful models may require a higher-amperage circuit.
Can you run a 1200 watt microwave on a 15 amp circuit?
Yes, you can run a 1200 watt microwave on a 15 amp circuit. A 15 amp circuit can handle up to 1800 watts, which is more than enough to power a 1200 watt microwave. However, it is important to ensure that the circuit is dedicated solely to the microwave to avoid overloading the circuit with other appliances. By installing a dedicated power source, you can safely operate the microwave without causing any electrical issues.
How many amps are microwave?
The average microwave generally consumes around 5 to 10 amps at 120V, which corresponds to 600 to 1,200 watts. However, if the voltage is doubled to 240 volts, the amperage is halved, resulting in a range of 2.5 to 5 amps.
