A grounded outlet helps safeguard both the microwave and your home’s electrical system, preventing potential hazards like short circuits or fires. This step ensures that your microwave operates safely and efficiently, while also improving the overall reliability of your electrical setup.
Without grounding, you risk damaging the appliance and compromising safety. Always check that the outlet and wiring meet grounding requirements to avoid electrical issues.
3. Position the Outlet Strategically
Positioning the outlet in an accessible, discreet location minimizes visible cords and reduces clutter. Proper placement also ensures ease of use, preventing the risk of accidents while maintaining a clean and organized kitchen space.
Location Tips:
- For countertop microwaves: Position the outlet above the counter but near the appliance for easy access.
- For built in microwaves or over-the-range microwaves: Install the outlet inside the cabinet or behind the unit, following manufacturer guidelines, ensuring proper clearance for the range hood.
4. Avoid Using Extension Cords
Ensure that the cord and plug connected to the outlet are adequate for the microwave’s power needs.
WARNING: Extension cords aren’t designed to support the high power draw of a microwave. Using one can lead to overheating or increase the risk of fire. If your microwave’s cord doesn’t reach the outlet, have a licensed electrician install an outlet in a more convenient location.
5. Choose GFCI or Standard Outlets Based on Location
Selecting the correct outlet type ensures safety and helps you meet electrical code requirements for your microwave installation. Depending on the location, you’ll need either a GFCI or standard outlet. Here’s how to determine which one to use:
- GFCI (Ground Fault Circuit Interrupter): Areas prone to moisture, such as near the sink or in kitchens without a dry zone.
- Standard Outlet: Dry zones, where moisture isn’t a concern, such as away from sinks.
Ensure compliance with National Electrical Code (NEC) and local regulations for safety.
6. Ensure Proper Amperage and Voltage
Using an outlet with insufficient amperage or voltage can prevent your microwave from functioning properly or even cause damage. For example, while a 700-watt microwave can be plugged into a outlet, a higher-wattage microwave, like a 1200-watt model, requires an outlet with a higher microwave outlet amp rating to operate safely.
This highlights the importance of checking the manufacturer’s specifications. Always ensure the outlet provides the correct power, typically 120V and 15-20A, to avoid potential issues.
If your home’s wiring doesn’t meet these requirements, consider upgrading your electrical system with a professional’s help.
