In this regard, what size breaker is needed for a microwave?
Our countertop and over-the-range microwaves:Require a 120 volt individual, properly grounded branch circuitwith a 3 prong grounding type receptacle, protected by a 15 or 20amp circuit breaker or time-delay fuse. Over-the-rangemodels should be on a dedicated circuit.
In this manner, which transformer is used in microwave oven?
Microwave ovens contain a very powerful highvoltage transformer (MOT = microwave oventransformer), see photo. A typical output voltage is 2kVeff, ataround 1000W power.
The 1200 watts is actually the microwavepower available for cooking or heating. The actual power thetransformer uses is shown on the back of the theoven. It could be something like 2000 watts. Thecurrent a transformer draws on its primary depends on theload on the secondary.
