Definition of Low Voltage Cabling

Low voltage cabling operates at less than 91 volts, transmitting data, signals, or low-level power rather than high-voltage electricity.

Key characteristics include:

  • Safer to handle than high-voltage wiring
  • Supports communication and control applications
  • Used in both residential and commercial projects

Common types of low voltage cabling include:

  • Ethernet (Cat5e, Cat6, Cat6A)
  • Coaxial cable (RG59, RG6)
  • Fiber optic cable
  • Speaker and control wiring

Networking and Data Communication

Ethernet and Structured Cabling

Low voltage cabling is the backbone of networking:

  • Cat5e, Cat6, Cat6A: Used in homes, offices, and data centers
  • Fiber Optic Cabling: High-speed backbone and long-distance connections
