You are watching: How many watts does a microwave draw

How much existing (Amps) and appliance paint, etc is a really important consideration details when it comes to the electric design and safety. So how numerous amps go a microwave cooktop draw?Typically, a microwave oven draws from 9 Amps – 15 Amps at 120 Volts or around 5 Amps – 9 Amps at 220 Volts relying on the input strength rating.That is a reasonably vast selection and therefore, in order come pin point the present amp rating for your microwave, the is necessary to read and understand the voltage, current and also power specifications of your microwave.Here we will particularly talk about microwave amp rating as well as talk about why the matters.

How plenty of Amps does a Microwave range Draw?

The present drawn counts on the traditional voltage rating in your country
As pointed out earlier, a microwave ovens paint, etc anywhere in between 9 Amps to 15 Amps escape at 120 volts.The lot of drawn present depends ~ above the INPUT power rating of the microwave oven. The greater the INPUT power rating, the much more current the microwave range will draw.Below we have compiled a fast guide about the intake power worth of a microwave and also its equivalent amperage for both 120 and also 220 volts.Note that amperage is a function of both power and also voltage. Voltage is generally standard in a particular country. In united state the traditional voltage is 120 V and for Europe and also Asia the standard voltage is 2202.

Operating Voltage 120V (US)

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

Operating Voltage 220 (Europe, Asia)

At 220 volts, the current draw is lower. Why, since the greater the voltage, the reduced is the current drawn.1100 W entry – 5 Amps1300 W entry – 5.9 Amps1500 W intake – 6.81 Amps1700 W intake – 7.72 Amps1850 W input – 8.4 AmpsAlso Read: Which kind of Microwave oven is ideal for house Use?

How to calculate the Amps Draw?

The figures mentioned over are just for your information, you deserve to calculate the current (amps) attracted by a microwave yourself utilizing a simple formula:
In stimulate to use this formula, friend will need to understand the input power and also the standard wall voltage in her country. Again for us the standard voltage is 120 V and for Europe and also Asia it is 220 V.The beauty around this equation is the it can be offered for all electrical devices. All you have to know, in essence, is the input power of the appliance. Voltage is an ext or less well-known anyways.However, the is utmost prestige that you use the INPUT power value and NOT the OUTPUT strength value as soon as calculating the present drawn.

Input and also Output Power

You will an alert that microwave ovens, like all devices, have actually two strength ratings i.e entry power and output power.You will also notice that the output strength of a microwave oven is much reduced than the intake power.This is due to the fact that no electrical an equipment is a 100% efficient. Microwave ovens are about 65% efficient. An interpretation 65% of the power drawn (Input Power) in converted right into microwave power (Output Power).For circumstances a 700W microwave oven, which is thought about the weakest microwave course for residence use, color etc in around 1100 watt of power if it has a usual efficiency of 65%.Let us see few of the typical input and also output strength values. Right here the calculation power value is based upon 65% efficiency.1100 W entry – 700 W Output1350 W entry – 900 W Output1700 W entry – 1100 W OutputIt have to be provided that performance is various from model to model. Some are far better at convert input power more efficiently to output microwave energy, others room less.The most an effective class of microwave ovens for residence use typically have an output power of 1250 W. This would attract in a strength of about 1850W.The point to note here is that as soon as calculating the amps, you have to use the much higher Input power value. The higher the power, the greater would be the amp drawn.Also Read: Microwave Wattage intake or output – i beg your pardon One Matters?

Importance of learning the Microwave Amp Draw

The amps attracted by any kind of appliance is critical consideration as soon as it involves sizing the electrical materials or when building the circuit design for your kitchen.

1. Circuit Design

You need to know the amount of amps (load) linked to her circuit in her kitchen prior to you decide on developing it.A usual kitchen style may have 2 specialized 20 amps circuits. However, if you have a many high it is provided appliances, say a very powerful microwave oven, climate you might need more specialized circuits.Dedicated Branch CircuitA low powered microwave oven illustration a fairly low amount of existing can be linked to an electrical wall surface socket conveniently without having actually to worry around the breaker tripping.However, if you have actually a high powered microwave illustration in a most amps, you may need to install a dedicated circuit simply for that.A dedicated circuit is one that has a different breaker installed. The breakers additionally have one Amp rating that their own such as 15 Amps, 20 Amps etc. What this means is that IF the connected total amperage of the appliances over the breaker amperage rating, climate it will certainly trip.This is for you own safety against short circuits and also power surges.According come American requirements a single breaker should not be used at much more than 80% the its amperage rating. thus the maximum linked load to a 20 Amp breaker should not be much more than 16 Amps. Similarly, a 15 Amps breaker must not be associated to a an equipment (or devices) that draws more than 12 Amps that current.Hence if you have a high it is provided countertop microwave oven with a rated input strength of 1850W drawing about 15 Amps of current at 120 Volts (as discussed earlier) girlfriend will require to have a specialized branch circuit with a 20 Amps breaker set up at least.Similarly, if you have a short powered countertop microwave oven rated at 1100W entry power illustration in 9.16 Amps of current at 120 Volts, then you will require a breaker that has about 12 Amps rating.It should likewise be pointed out that because that affixed or set up microwave ovens prefer over-the-range microwaves or integrated microwave, their current drawn must not exceed 50% of the breaker rating (according to American Standards)Also Read: Best Microwaves because that Dorm – small and MediumFuse and Component SizeAnother important consideration of the existing drawn through a microwave is that it relates to the size of the components within the microwave itself.From diodes, capacitors come fuse, all room dependent upon the quantity of current drawn.For instance, the fuse is a ingredient that just like a breaker, division the electrical current if over there is a quick circuit or a power surge.The fuse is usually sized at about 135% the the rated input current of a device. Therefore if her microwave range is illustration in about 10 Amps of current, the fuse will must be rated at about 13.5 Amps for her safety.

2. Extension Cord Gauge

Finally, how countless amps a microwave oven draws has critical role if you desire to usage it end an expansion cord.While using a high powered electrical maker is not recommended end an expansion cord, if girlfriend absolutely have to, girlfriend then need to take into factor to consider the input existing of your machine and then decide on the corresponding gauge (diameter) that the expansion cable.

The greater the current drawn, the more thickness the cable would must be.
