240 Volt Extension Cord – Top 5 choices in 2022

In a perfect world, you would never need to use a 240-volt extension cord, simply because there would always be a socket where you need it. Of course, this is rarely the case. Even in a custom-designed home you will eventually add or move items, changing the dynamics of the space. 

The simple answer, when your appliance doesn’t have a long enough cord, is to use an extension cable. But, before you rush to the store and grab the first one you see, you should be aware that extension cords can be dangerous. 

The Danger Of A 240 Volt Extension Cord

Extension cords are simply several copper wires inside insulation and wrapped in a piece of plastic. The design is pretty straightforward. But, as electricity passes through the individual wires, it creates heat. The greater the heat the higher the possibility that the surrounding insulation and plastic will melt. This causes short circuits and house fires.

The most common reason why this happens is that the extension cable has been incorrectly sized and is overloaded. Put simply, you have too many items plugged in drawing too much current. Or, the cable has been left coiled, allowing the heat within the wires to build up faster and start a fire.

Consideration Before Buying

Before you part with your hard-earned cash and choose any extension cable, there are a few things that you should consider, it will help you to choose the perfect 240-volt extension cord:

  • Manufacturer

Knowing the safety risks associated with a 240-volt extension cord means it is particularly important that you choose the manufacturer carefully. This will ensure that you can trust the quality of the materials used and that the extension cable is as described. 

When choosing your extension cable it is best if you already know and have had a positive experience with the manufacturer.

 But, if this isn’t the case you can ask family and friends what they know about a specific manufacturer. If that doesn’t help you can look for information on social media, online forums, and guides like this one. It is the most effective way of getting honest feedback and choosing the right extension cable.

  • Number Of Sockets

The next thing to consider is how many sockets does your extension cable need. You can purchase extension cables with just one socket, or as many as eight sockets. However, you should remember that most household circuits are designed to take eight sockets and no more, having that many on the extension will increase the likelihood of overloading the circuit and causing issues.

The best approach is to decide how many sockets you really need and stick to that number. 

  • Length

This is a fairly obvious consideration. The point of an extension cable is to effectively move an electrical outlet from one place in the room to another. To do this you need to know how long the distance is, including laying it around shapes and structures in your room. After all, you want it to look tidy and not to be a trip hazard.

Getting the length right is important, if it is too long the cable will end up coiled, increasing the risk of a fire.

  • Thickness of the wire

The wire inside a 240-volt extension cord comes in a variety of thicknesses. This is referred to as the gauge of the wire, the thicker it is the more current it is capable of carrying. To reduce risk it is better to choose a lower gauge wire.

Gauge is referred to as an AWG (American Wire Gauge) number. The lower the number the thicker the wire and, therefore, the higher the current it can handle. 

Don’t forget that distance makes a difference. The longer the cable the more the voltage will drop. To decide the minimum rating you need to know the amperage of your appliance.

For example, an 18 AWG cable will be rated at 5 or 7 amps and can effectively deliver this up to 25 feet. But, thanks to voltage drop, if you use a 50ft cable you will need a 16 AWG to deliver the same amount of amps.

  • Surge Protection

You should spare a few moments to consider whether your 240-volt extension cable needs surge protection, or not. Most modern circuit boards use circuit breakers which react very quickly when there is an issue with the electrical circuit. However, they may not react quick enough to prevent surges in electricity, which are much more common than you may think.

Fluctuations in the power supply can cause damage to electronic components, especially those with sensitive chipboards. If you are using sensitive or expensive equipment, surge protection built into your extension cable should be considered essential.
