What Size Breaker for a Microwave?

Microwaves of all types require a batch of power tied compared to other kitchen appliances- much more than some racing circuit breakers are able of safely providing, so knowing what size circuit breaker for a microwave to use is an essential part of safely operating it .
KEY TAKEAWAYS:

  • The size of the circuit breaker determines how much power an appliance can draw safely without the risk of tripping the breaker.
  • Larger 1000-1100 watt microwaves absolutely require a 20 Amp breaker for safe and optimal use.
  • Though a 15 Amp circuit is generally sufficient for lower-wattage (600-700 watt) microwave ovens, a 20 Amp circuit is still the recommended size for safe and reliable use.

The best microwaves will be wired properly for safe use even without a give lap, but understanding the world power requirements of kitchen appliances will allow you to make certain you never run into potentially dangerous electrical issues. Understanding the electric needs will besides help you better understand coarse microwave issues, such as why sometimes microwave ovens hotness unevenly .
Insider Tip

If possible, it ’ randomness best rehearse to use a 20 Amp circumference evening for a low-wattage microwave oven and to use a consecrated circuit .

Circuit Breakers and Kitchen Appliances

Kitchen appliances frequently have a high office prerequisite, and sometimes more than can be provided by a individual standard home circuit breaker if it ’ south shared with early appliances or lights in the home .
Microwave ovens- particularly large over-the-range microwave ovens – have higher office requirements than most, and because of that, electrical issues result in dimming house lights or blow fuses that can occur more often than it does in other appliances. That ’ second why plugging your microwave into its own dedicate electric circuit ( a separate tour ) so that it ’ s not sharing power cargo with house lights or other appliances is important .
however, it ’ s besides important to know what size tour breaker your microwave requires. For the most part, your home will already have the allow size, but it ’ s a good estimate to know for certain, and if you ’ re doing renovations or building a new base, the appliances you ’ re going to be using is an crucial thing to plan for .

Standard Breaker Sizes for Microwave Ovens

Most microwaves require a dedicate 20-amp 120/125-volt circuit with a time-delay blend to feed it power, using a 12/2 NM grounded wire. These are much standard in homes, but you may wish to consult either your utility program company or surf box for this information to confirm- though the latter may not constantly be potential .
Some larger microwave ovens, including many over-the-range microwaves, can draw a much as 1700 watt of exponent. Making certain you have the appropriate microwave oven tour and that the microwave has its own dedicate mercantile establishment and circumference ( and not, as happens often, one shared with a refrigerator ) is even more crucial for condom operation without the risk of dimming lights, blow fuses, brown-outs, or other electrical issues .
additionally, many building codes dictate specific rules for kitchen circuits and standard appliance outlets- these are sometimes even shown on a surf ’ mho jury. consultation with or advice from a license electrician to be sure you ’ re in conformity with local electric code is powerfully advised hera .
Warning

Though it ’ sulfur common to see microwaves, including high-wattage over-the-range microwaves, on 15 Amp circuits, they should always use 20 Amp circuits or they can ’ thyroxine be considered condom to use .
F.A.Q.S
Is a 15-Amp breaker big enough for an 1100 watt microwave?
Though it ’ s not rare to see large microwaves ( specially over-the-range models ) using a 15 adenosine monophosphate tour circuit breaker, any microwave oven this boastfully should absolutely use a dedicate 20 ampere breaker or 20A circuit for optimum safe use .
What size breaker do I need for a 1000 watt microwave?
A 1000 watt microwave oven draws around a 1700 watt of rampart exponent evaluation, which is around 14 amps, however, even smaller 700-watt microwaves should ideally use a give 20 Amp circumference for optimum safe manipulation, and this goes doubly for larger 1000+ watt models .
Do microwaves absolutely need a 20 Amp circuit or is it merely best practice?

While it ’ randomness coarse for many users to plug their microwave into a 15 Amp circuit, it can ’ thymine be considered 100 % safe or risk-free, even if it ’ s a low-wattage 600 or 700-watt model. For 1000+ watt models, it ’ s not just a bad estimate, it ’ s a must .

STAT: Most tour breakers will not stumble until they ’ ve hit 20 % over the maximum exponent they ’ rhenium rated for. ( reference )
