What size fuse do microwaves use?
20 amp
The electrical and breaker size requirements for our Countertop and Over-the-Range Microwaves are as follows: The microwaves require a 120 volt, individual, properly grounded branch circuit with a 3 prong grounding type receptacle protected by a 15 or 20 amp circuit breaker or time-delay fuse.

What is the difference between 125V and 250V fuse?
For example, a 125V fuse can be replaced with a 250V fuse of equal amplitude while the voltage of the application is 250V or lower, but a a 250V fuse can’t be replaced with a 125V fuse of equal amplitude if the voltage of the application exceeds 125V.
Why does my microwave keep blowing the fuse?
If the microwave blows a fuse when started, the most likely cause is that the high-voltage capacitor has shorted out and needs to be replaced.
Why would a microwave keep blowing a fuse?
Does a microwave need a 20 amp circuit?
Microwave Oven Circuit The microwave oven needs a dedicated 20-amp, the 120/125-volt circuit to feed it. This will require 12/2 NM wire with a ground. Microwave ovens come in different varieties and sizes. Some are countertop models, and other microwaves mount above the stove.
Do you need a special fuse for a microwave?
Microwaves usually contain several types of fuses for safe operation. A main fuse or line fuse is a fuse that will cut the flow of electricity if too much current passes through it. Conversely, a thermal fuse will prevent electrical flow if the fuse is heated to a specific temperature.
What happens if you use 250V fuse instead of 125V?
A 250 volt fuse is likely to blow out a 125 volt electronics that was not designed to withstand such high power. You don’t want to send 250 volts to a 125 volt circuit.
Can I replace a 250V fuse with 125V?
Why does my microwave keep blowing its fuse?
Why would a fuse keep blowing in a microwave?
If a microwave fuse keeps blowing, it may be because the fuse is not being installed correctly or that the wrong type of fuse is being installed. Microwave parts like door switches or the magnetron, if defective or wrongly installed, will also cause microwave fuses to continuously blow.
Does a microwave need a 15 or 20 amp outlet?
Microwaves require a 20-amp branch circuit due to constant load and spike issues. Under strenuous use, a microwave could draw nearly the maximum 15 amperes of current regularly for hours. Under this maximum load scenario, 14- gauge wiring could heat up beyond safe levels.
