Low voltage wires are an easy and safe way to power many devices around your home. While not all devices can run on low voltage, those that do will benefit from its cost-saving qualities and safer performance. These are some of the highest-rated low voltage wires of 2024 that you’ll want to have in your own home.
While a lot of your home appliances run on relatively high voltage, not all of them do. Some of the simpler devices, such as doorbells and garage door openers, require barely any power to function. Because of this, it’s often unnecessary to give these devices the full voltage, and in many cases, it’s even safer to just use low-voltage wires instead.

Buying Guide: Low Voltage Wires
What Is a Low Voltage Wire?
A low voltage wire is a wire that doesn’t use the same voltage as a regular wire found at home, also known as a line voltage wire. You see, not all electronic appliances use the same amount of voltage. Some devices are perfectly fine with the voltage in your home, whereas others may require less of it. The latter type of device would have to use low-voltage wires to properly run.
The Advantages of Low Voltage Wires
They allow certain types of devices to work
There are quite a few devices designed to work only at low voltage. This can vary from device to device, but generally, electronics that can run on low voltage do run on low voltage. Of course, there are options for those that do not have low voltage wires, but if you want to use a device that only runs on low voltage, you’ve got no choice but to get some.
They’re cheaper to operate in the long run
One interesting thing to note is that low voltage wiring is actually cheaper to use in the long run. Due to the low voltage, you can save quite a lot of money, and this can be used to buy other things or save up for stuff you’ve been looking to add to your home.
The Limitations of Low Voltage Wires
They cannot power regular appliances
Appliances that run on regular line voltage will likely not run on low voltage wire. This is because the low voltage is too unstable and doesn’t offer enough power for the device to work. It’s especially dangerous when using old devices — the motors and components can overheat when subject to the low voltage, which can damage the appliance and cause it to overheat.
Fortunately, that scenario won’t happen with new appliances. Virtually every modern appliance uses an electric motor with components that detect whether or not the voltage is too low. In the event that the voltage is too low, the device will simply cease its functions. It’s a lot safer than before, but you’re still left with a powerless device until you plug it into a regular line voltage outlet.
They are generally more expensive
Despite being cheaper to use, low-voltage wires cost more upfront. This is also true with low-voltage appliances and devices — they generally cost a little more than those that do not run on low voltage. This means that, while you will save a bit in the long run, you will have to spend a little extra to get things going.
Types of Low Voltage Wire
Indoor low voltage wire
An indoor low voltage wire isn’t meant to withstand the harsh environmental conditions of the outside world. That said, it does offer great insulation and looks nice even when exposed. You’ll notice that many indoor low voltage wires look a little more presentable than their outdoor counterparts. They’re slightly more premium in terms of looks and some come in a white color that blends well with most walls.
Indoor low voltage wires are easy to set up and can look great when properly wired and installed. As long as you know what you’re doing, indoor low voltage wires can help set up your devices nicely without taking away from the beauty of your home.
Outdoor low voltage wire
Outdoor low voltage wires are a lot tougher than indoor wires. They’re usually buried underground for lighting and other purposes, which exposes the wires to a lot of water and moisture. Fortunately, outdoor wires are water-resistant and weather-resistant, ensuring that nothing short-circuits or gets damaged just because of a rainy day.
People Also Asked
What are low voltage wires used for?
Low voltage wires are used to power certain lights, doorbells, garage door openers, and other simple electronics.
Do light bulbs need low voltage wires?
Not all of them do. Many light bulbs run on line voltage, which is the voltage that comes from your power outlet. Some bulbs, on the other hand, require low voltage only, such as landscape lights.
Are low voltage wires necessary?
While not exactly necessary per se, they are safer and more affordable to own than regular line voltage wires.
