Microwave Extension Cord – Buyer’s Guide 2023

The microwave was first sold in 1946. The technology is actually based on radar developments which were essential during the Second World War. Perry Spencer is credited with inventing the microwave. However, it took many years for them to become an accepted part of the modern kitchen. Many people were concerned about introducing radio waves to their food.

Today, most homes have one and it is seen as an essential item, helping to ensure food can be easily reheated and meals can be eaten as needed. This is particularly relevant as families no longer always eat together.

Unfortunately, microwaves generally come with short power cords, this can seriously limit where you position them in your home. The best way to resolve this issue is to use a dedicated microwave extension cord.

That’s why it’s important to look at the following microwave extension cords and choose the one that best suits your needs. And don’t worry they might be on the heavy-duty side, but they don’t look like Heavy Duty Outdoor Extension Cords, you don’t have to ruin your kitchen design.

Considerations When Choosing The Best Microwave Extension Cord

There are several things you should be aware of before you decide which microwave extension cord you want to purchase:

  • Reputation

A microwave extension cord plugs into your existing electrical circuits and effectively creates a new socket for your microwave, closer to where you want it to be. In most cases, the cable will operate fine for years. But you need to be aware that electricity is potentially dangerous and a bad extension cord will increase the risk of fire.

To help protect against this you need a cord made by a reputable manufacturer. If you don’t already know the manufacturer you should check them out. The best way to do this is on social media and online forums. You should easily find people that have used the product and can tell you about their experience.

It’s important to note that manufacturers rarely get 100% positive feedback. But, for it to be high-quality most of the feedback should be. The negative comments are very useful to help you understand how the manufacturer reacts. It can be relevant if you have an issue.

  • Length

It’s a good idea to keep the cable as short as possible, this reduces the risk. This means you need to know how much cable you need and get a cable as close to that as possible. You can’t leave an extension cable coiled up, it increases the risk of fire. But, if the cable is too long it will trail and is likely to be a trip hazard.

That’s why it’s best to calculate the desired length and get as close to it as possible.

  • Wiring

All microwave extension cables should be three-core. That means there are three cables inside the wire, a live, an earth, and the neutral. This ensures the microwave is grounded, ensuring the electricity goes to ground if there is an issue.  

  • Positioning

As mentioned, the length of the microwave extension cable is important to avoid creating a trip hazard. As well as choosing the right length and type of cable, you should ensure that it can be clipped out of the way safely. This can affect the length of the table but will reduce the likelihood of issues.

Don’t forget, the extension cable must plug into a three-pronged socket.

What Gauge Is the Extension Cord Best for Microwave?

The best gauge for an extension cord for a microwave is 14 AWG (American Wire Gauge). It is the most common type of wire used in homes and offices, making it easy to find in stores and online.

Microwave extension cords come in a variety of lengths and gauges. Each gauge has its own set of benefits. The higher the number, the thicker the wire is so it can carry more electrical current. 

How Many Amps Do They Need?

While you should always check your specific model of microwave to see how many amps it needs, on average, you need an extension cord that can handle at least 15 amps

If you want to be safe and get a more powerful cord, then aim for one that can handle at least 20 amps. Otherwise, 15 amps is the very minimum you should get.
