How Many Amps Does a Microwave Use? (Explained)

How many amps does a microwave use? The answer might be more than you think. There are several electrical requirements to know before operating a microwave.

This is due to the powerful nature of microwaves and how much energy they use. In this article, we will tell you all you need to know. Read on.

How Many Amps Does a Microwave Use?

A microwave uses between 5.4 amps and 10 amps depending on how much power is being drawn by the appliance at the time. This means that a high-powered microwave will use more power than a low-powered one, even if they’re set to heat food using exactly the same settings.

The reason for this discrepancy is that a high-powered microwave will heat food faster and therefore draw more power from the mains. To put this into context, a 1000w microwave will use around 10 amps at full pelt.

What are Amps?

An amp is the unit of measurement for current flow, or how much electricity is flowing through a wire. It’s also known as an ampere, but amps is the term most often used in electronics.

Amp ratings appear with electric motors and other devices that use electricity to perform work.

The higher the amp rating number, the more electrical current a device can handle without burning out. The amp rating is important for protecting the device and for providing safety for people working with it.

How are Amps Calculated?

Amps = Watts/ (Volts x Power Factor) Power Factor is the ratio of working power to apparent power. It can be found by dividing “true” or “working” power by apparent power. True power is how much work a device actually does, and it can be measured in watts.

Apparent power is how much power is required to run the device. This number will always be higher than true power, due to inefficiencies that occur when converting electricity from one form to another.

Can a Microwave be on a 15 Amp Circuit?

Yes, a microwave can be on a 15 amp circuit. However, it must not exceed 15 amps and the circuit breaker must be adequate to handle the load. All equipment that is on the same circuit as the microwave oven must also be able to handle a 15 amp load.

For example, in addition to the microwave, any other equipment on the same circuit should be rated for 15 amps or less as well. The reason for this is that you want to prevent overheating, short circuits, and possible fires due to overloading.

Does a microwave need a 20 amp circuit?

Yes, a microwave oven needs a dedicated 20-amp, 120/125-volt circuit. A microwave should not share a circuit with another appliance, especially a refrigerator. Dedicated circuits ensure that your microwave will always have the power it needs to operate safely and efficiently.

If you’re installing a new microwave in an older home without dedicated receptacles for appliances, you need to check the capacity of your electrical panel and hire an electrician if necessary.

How many amps does a 1000-watt microwave use?

A “1000 watt” microwave will take approximately 1700 watts of power from the wall. That is 14 amps when divided by 120 (volts). You should install at least a 20 amp circuit for such a microwave.

Even if there isn’t anything else on the circuit. Microwave ovens require more power than most wall sockets are able to provide. Any time you use an extension cord to try and power something, you are taking a risk of endangering yourself, your property, and your loved ones.

Is a microwave 15 or 20 amp?

Microwaves require a 20 amp circuit. If the circuit is 15 amp and you plug in a 20 amp appliance, it is possible that the breaker will trip or the switch will be fried. So make sure your circuit breaker is 20 amps or larger.

Does a microwave need a special outlet?

A microwave oven does not need a special outlet. It is simply a high-powered appliance that consumes a lot of electricity and needs its own dedicated circuit.

The wire gauge (the thickness of the wire) has to be adapted to the power consumption of the microwave oven, and it needs to be plugged into an appropriately sized circuit breaker, but there is nothing special about the kind of outlet that it uses.
