You are watching: How many volts does a microwave use

How much existing (Amps) and also appliance color etc is a really important consideration details when it involves the electrical design and also safety. Therefore how plenty of amps walk a microwave range draw?**Typically, a microwave range draws indigenous 9 Amps – 15 Amps in ~ 120 Volts or around 5 Amps – 9 Amps in ~ 220 Volts relying on the input strength rating.**That is a fairly vast selection and therefore, in order to pin suggest the existing amp rating for her microwave, the is important to read and understand the voltage, current and also power specifications of your microwave.Here we will specifically talk about microwave amp rating and talk around why that matters.

## How plenty of Amps does a Microwave stove Draw?

The existing drawn counts on the standard voltage rating in your country

As mentioned earlier, a microwave ovens color etc anywhere in between 9 Amps come 15 Amps escape at 120 volts.The lot of drawn current depends top top the INPUT power rating of the microwave oven. The greater the INPUT strength rating, the more current the microwave cooktop will draw.Below we have compiled a fast guide regarding the intake power value of a microwave and its corresponding amperage because that both 120 and 220 volts.Note that amperage is a role of both power and also voltage. Voltage is generally standard in a details country. In united state the standard voltage is 120 V and also for Europe and Asia the standard voltage is 2202.

### Operating Voltage 120V (US)

Here we have taken the Input strength of the microwave (not the calculation power).**1100 W entry – 9.16 Amps**

**1300 W intake – 10.83 Amps**

**1500 W input – 12.5 Amps**

**1700 W intake – 14.16 Amps**

**1850 W entry – 15.14 Amps**

### Operating Voltage 220 (Europe, Asia)

At 220 volts, the present draw is lower. Why, since the greater the voltage, the reduced is the current drawn.**1100 W entry – 5 Amps**

**1300 W input – 5.9 Amps**

**1500 W entry – 6.81 Amps**

**1700 W entry – 7.72 Amps**

**1850 W entry – 8.4 Amps**

## How to calculate the Amps Draw?

The numbers mentioned over are simply for her information, you can calculate the present (amps) attracted by a microwave yourself using a straightforward formula:In bespeak to use this formula, friend will need to understand the entry power and also the standard wall surface voltage in your country. Again for us the typical voltage is 120 V and for Europe and also Asia that is 220 V.The beauty about this equation is the it have the right to be used for all electrical devices. All you need to know, in essence, is the input strength of the appliance. Voltage is much more or less well-known anyways.**However, it is utmost prestige that you usage the INPUT strength value and NOT the OUTPUT power value as soon as calculating the existing drawn.**

### Input and Output Power

You will notice that microwave ovens, prefer all devices, have two strength ratings i.e intake power and output power.You will certainly also an alert that the output power of a microwave oven is much reduced than the entry power.**This is because no electrical machine is a 100% efficient.**Microwave ovens are around 65% efficient. Meaning 65% of the power attracted (Input Power) in converted right into microwave power (Output Power).For instance a 700W microwave oven, which is considered the weakest microwave course for home use, color etc in around 1100 watts of power if it has actually a common efficiency the 65%.Let us see some of the common input and also output strength values. Here the output power value is based on 65% efficiency.

**1100 W entry – 700 W Output**

**1350 W intake – 900 W Output**

**1700 W intake – 1100 W Output**It need to be listed that efficiency is various from model to model. Some are better at converting input power more efficiently to output microwave energy, others room less.The most powerful class that microwave ovens for house use generally have one output strength of 1250 W. These would attract in a strength of around 1850W.The allude to note below is that when calculating the amps, you have to use the much greater Input power value. The greater the power, the greater would it is in the amp drawn.

## Importance of knowing the Microwave Amp Draw

**The amps drawn by any kind of appliance is vital consideration once it pertains to sizing the electrical contents or when building the circuit style for her kitchen.**

### 1. Circuit Design

You have to know the quantity of amps (load) linked to your circuit in her kitchen prior to you decide on developing it.A usual kitchen architecture may have 2 committed 20 amps circuits. However, if you have actually a lot of high powered appliances, say a very powerful microwave oven, then you might need more devoted circuits.Dedicated Branch CircuitA low powered microwave oven illustration a reasonably low quantity of existing can be connected to one electrical wall socket conveniently without having to worry about the breaker tripping.However, if you have actually a high powered microwave illustration in a many amps, you may need to install a devoted circuit simply for that.A dedicated circuit is one that has a different breaker installed.**The breakers likewise have one Amp rating that their very own such as 15 Amps, 20 Amps etc**. What this means is that

**IF the linked total amperage the the appliances over the breaker amperage rating, then it will trip.**This is for you own safety against short circuits and also power surges.According come American standards a single breaker must not be supplied at much more than

**80% that its amperage rating.**thus the maximum connected load to a 20 Amp breaker should not be much more than 16 Amps. Similarly, a 15 Amps breaker need to not be linked to a device (or devices) that draws an ext than 12 Amps of current.Hence if you have a high powered countertop microwave cooktop with a rated input strength of 1850W drawing around 15 Amps of current at 120 Volts (as discussed earlier) friend will need to have a dedicated branch circuit through a 20 Amps breaker set up at least.Similarly, if you have actually a short powered countertop microwave range rated in ~ 1100W entry power illustration in 9.16 Amps of current at 120 Volts, climate you will require a breaker that has roughly 12 Amps rating.It should additionally be discussed that for affixed or set up microwave ovens choose over-the-range microwaves or integrated microwave, their existing drawn have to not exceed 50% that the breaker rating (according to American Standards)

*Best Microwaves for Dorm – tiny and Medium*Fuse and also Component SizeAnother important consideration of the present drawn through a microwave is the it relates to the size of the contents within the microwave itself.From diodes, capacitors come fuse, all are dependent ~ above the amount of existing drawn.For instance, the fuse is a component that just like a breaker, breaks the electrical present if over there is a brief circuit or a power surge.

**The fuse is usually sized at around 135% that the rated input existing of a device**. For this reason if your microwave range is drawing in around 10 Amps that current, the fuse will must be rated at around 13.5 Amps for her safety.

### 2. Extension Cord Gauge

Finally, how plenty of amps a microwave oven draws has an important role if you want to use it end an extension cord.While utilizing a high it is provided electrical maker is no recommended over an extension cord, if you absolutely have actually to, girlfriend then need to take into consideration the input present of your device and climate decide top top the corresponding gauge (diameter) of the expansion cable.See more: Which Is Not A Property Of All Similar Triangles ?
