What Is Low Voltage Cabling?

Low voltage cabling refers to wiring systems operating at 91 volts or less. These systems are widely used because they are safer, easier to install, and more energy-efficient compared to high-voltage wiring.

Common applications include:

  • Ethernet and data networking
  • CCTV and security systems
  • Access control and intercom systems
  • Audio/visual systems
  • Smart building automation

Even though low voltage cabling is safer than high-voltage wiring, professional installation is recommended to avoid signal interference, damage, or code violations.
