You are watching: How many amps does a microwave use

How much present (Amps) and also appliance draws is a really important consideration particular when it involves the electric design and safety. So how countless amps go a microwave oven draw?Typically, a microwave range draws native 9 Amps – 15 Amps at 120 Volts or about 5 Amps – 9 Amps in ~ 220 Volts depending on the input power rating.That is a reasonably vast range and therefore, in order come pin allude the existing amp rating for her microwave, that is essential to read and also understand the voltage, current and power specifications of your microwave.Here us will specifically talk about microwave amp rating as well as talk about why the matters.

How many Amps does a Microwave range Draw?

The present drawn counts on the typical voltage rating in her country
As stated earlier, a microwave ovens draws anywhere between 9 Amps to 15 Amps escape at 120 volts.The quantity of drawn present depends ~ above the INPUT strength rating of the microwave oven. The greater the INPUT strength rating, the an ext current the microwave range will draw.Below we have compiled a fast guide regarding the entry power value of a microwave and its corresponding amperage for both 120 and 220 volts.Note the amperage is a duty of both power and voltage. Voltage is usually standard in a particular country. In us the conventional voltage is 120 V and for Europe and Asia the typical voltage is 2202.

Operating Voltage 120V (US)

Here we have actually taken the Input power of the microwave (not the calculation power).1100 W entry – 9.16 Amps1300 W input – 10.83 Amps1500 W intake – 12.5 Amps1700 W entry – 14.16 Amps1850 W intake – 15.14 Amps

Operating Voltage 220 (Europe, Asia)

At 220 volts, the current draw is lower. Why, since the higher the voltage, the lower is the existing drawn.1100 W intake – 5 Amps1300 W input – 5.9 Amps1500 W input – 6.81 Amps1700 W entry – 7.72 Amps1850 W intake – 8.4 AmpsAlso Read: Which form of Microwave cooktop is ideal for home Use?

How to calculate the Amps Draw?

The figures mentioned above are simply for your information, you deserve to calculate the present (amps) attracted by a microwave yourself making use of a basic formula:
In bespeak to usage this formula, friend will need to understand the intake power and the standard wall voltage in your country. Again for united state the standard voltage is 120 V and also for Europe and also Asia the is 220 V.The beauty about this equation is the it have the right to be provided for all electric devices. All you have to know, in essence, is the input strength of the appliance. Voltage is more or less well-known anyways.However, it is utmost prestige that you use the INPUT power value and also NOT the OUTPUT power value when calculating the existing drawn.

Input and Output Power

You will an alert that microwave ovens, prefer all devices, have actually two strength ratings i.e entry power and output power.You will certainly also notice that the output strength of a microwave cooktop is much reduced than the entry power.This is because no electrical maker is a 100% efficient. Microwave ovens are about 65% efficient. An interpretation 65% the the power drawn (Input Power) in converted right into microwave power (Output Power).For instance a 700W microwave oven, i m sorry is considered the weakest microwave class for home use, paint, etc in about 1100 watt of strength if it has actually a usual efficiency of 65%.Let us see several of the usual input and output power values. Below the calculation power value is based upon 65% efficiency.1100 W input – 700 W Output1350 W input – 900 W Output1700 W intake – 1100 W OutputIt have to be detailed that effectiveness is various from model to model. Some are better at convert input power more efficiently to calculation microwave energy, others room less.The most an effective class of microwave ovens for residence use typically have an output strength of 1250 W. These would attract in a power of around 1850W.The allude to note here is that once calculating the amps, you need to use the much greater Input strength value. The higher the power, the greater would it is in the amp drawn.Also Read: Microwave Wattage input or calculation – i m sorry One Matters?

Importance of understanding the Microwave Amp Draw

The amps attracted by any type of appliance is crucial consideration when it concerns sizing the electrical components or when building the circuit design for your kitchen.

1. Circuit Design

You have to know the amount of amps (load) associated to your circuit in your kitchen before you decide on creating it.A typical kitchen design may have actually 2 committed 20 amps circuits. However, if you have a the majority of high it is provided appliances, to speak a very an effective microwave oven, climate you might need more committed circuits.Dedicated Branch CircuitA low powered microwave oven illustration a reasonably low quantity of existing can be linked to one electrical wall socket quickly without having actually to worry around the breaker tripping.However, if you have actually a high powered microwave drawing in a most amps, girlfriend may need to install a devoted circuit just for that.A specialized circuit is one that has actually a different breaker installed. The breakers likewise have an Amp rating the their own such as 15 Amps, 20 Amps etc. What this way is that IF the connected total amperage that the appliances exceeds the breaker amperage rating, climate it will certainly trip.This is for you own safety versus short circuits and also power surges.According come American standards a solitary breaker should not be supplied at much more than 80% the its amperage rating. thus the maximum associated load come a 20 Amp breaker must not be much more than 16 Amps. Similarly, a 15 Amps breaker must not be linked to a machine (or devices) that draws more than 12 Amps the current.Hence if you have a high it is provided countertop microwave range with a rated input strength of 1850W drawing about 15 Amps of present at 120 Volts (as stated earlier) friend will need to have a specialized branch circuit with a 20 Amps breaker installed at least.Similarly, if you have actually a low powered countertop microwave cooktop rated at 1100W intake power drawing in 9.16 Amps of current at 120 Volts, climate you will need a breaker the has about 12 Amps rating.It should additionally be pointed out that because that affixed or set up microwave ovens like over-the-range microwaves or integrated microwave, their existing drawn should not exceed 50% the the breaker rating (according to American Standards)Also Read: Best Microwaves because that Dorm – small and MediumFuse and Component SizeAnother important factor to consider of the existing drawn by a microwave is the it relates to the dimension of the components within the microwave itself.From diodes, capacitors come fuse, all room dependent top top the lot of existing drawn.For instance, the fuse is a component that just like a breaker, division the electrical present if there is a brief circuit or a power surge.The fuse is generally sized at about 135% of the rated input present of a device. Therefore if your microwave oven is illustration in around 10 Amps the current, the fuse will need to be rated at around 13.5 Amps for your safety.

2. Expansion Cord Gauge

Finally, how plenty of amps a microwave cooktop draws has vital role if you want to use it end an expansion cord.While making use of a high powered electrical an equipment is no recommended end an extension cord, if you absolutely have actually to, friend then have to take into consideration the input present of your machine and climate decide on the matching gauge (diameter) the the extension cable.
