Voltage and Amperage Considerations

When it comes to plugging in your microwave oven, there are two important things to consider: voltage and amperage. Failing to properly take into account these two factors can cause serious problems in terms of safety and functionality.

First, let’s define these terms. Voltage is the electrical potential difference between two points in a circuit. In other words, it’s the amount of electrical pressure that’s pushing the current through the wires. Amperage, on the other hand, is the measure of how much electrical current is flowing through the wires at any given time.

Factors to Consider

  • Outlet Voltage: Different regions have different voltage sizes, for example, USA has 110-120 volts while Europe has 220 volts.
  • Microwave Wattage: Every microwave displays the wattage it uses, where lower wattages can work in standard circuits but higher wattages need a dedicated circuit of 20 amps to avoid blowing up the fuse.
  • Wire Amperage: Wires come with different capacity amperages, a thicker wire can handle higher amperages. If the wire capacity isn’t big enough to cover the microwave’s wattage and the circuit’s voltage, it can cause electrical shortages, malfunctions, or even a fire hazard.

Proper Installation Techniques

When installing a microwave, it’s important to use the right type of outlet. You should never plug a high-wattage appliance like a microwave into a standard 110-volt outlet; it’s simply not designed to handle that much power. Instead, you’ll need to use a dedicated 20-amp circuit outlet that’s specifically designed for high-wattage appliances.

If you’re not sure whether your outlet is capable of handling a microwave, you can always consult with an electrician. They’ll be able to assess your electrical system and recommend the best course of action to ensure your microwave is properly installed and runs safely.
