What is Low Voltage Wiring and When Do I Need It?

Low-voltage wiring can be found just about everywhere inside and outside your home or business. Lights, doorbells, thermostats, and TV and internet cables all use it. And with a wide variety of low-voltage wires, it can be used for so much more. But why exactly is low-voltage used, and how do you know if I need low-voltage wiring? Let’s take a more in-depth look!

Wire Gauges

A standard way to identify the gauge or thickness of electrical wire is with the AWG system (American Wire Gauge). Low numbers indicate thicker wires and high numbers indicate thinner wires. While AWG refers to solid, single-strand wire, it applies to stranded multi-wire low-voltage wiring as well. The diameter of a cross-section of multiple strands added together is equivalent to the solid, single-strand wire designation. Devices around the home that require higher voltage, such as outlets and lights, use 12- and 14-gauge wire. Low-voltage devices use wire that ranges from 12- to 24-gauge.

Low-Voltage Wire

Characteristics of low-voltage wire can differ greatly from those of higher-voltage wiring. While it is acceptable for low-voltage wire to be exposed or buried and in direct contact with the ground, the same cannot be said for high-voltage wiring. Low-voltage wiring is also used for things that high-voltage is not used for, including the following:

  • Doorbell wiring
  • Landscape lighting wiring
  • Network wiring
  • Phone wire
  • TV cable

A bundle of two low-voltage wires is what connects a doorbell to the base unit or chime, often located in a central location far away from the actual doorbell. Landscaping lighting uses double-strand 12-, 14-, or 16-gauge wire buried in the ground. Network wiring, like an Ethernet cable designed to carry broadband internet, is also considered low-voltage wiring, as is the wire used for closed-circuit security cameras.
