What Is Low Voltage Cabling?
Low voltage cabling refers to wiring systems that operate under 50 volts, commonly used for telecommunications, networking, security, and automation. Unlike standard 120V electrical wiring, low voltage systems are safer, energy-efficient, and optimized for data transmission.
Typical low voltage systems include:
- Structured data and voice cabling (Cat5e, Cat6, Cat6A, Cat7)
- Security camera and alarm systems
- Access control and intercoms
- Audio/visual and smart building integrations
- Fiber optic networking

- Cable Category: Cat6 costs less than Cat6A or Cat7 due to shielding and bandwidth capabilities.
- Cable Length: The longer the run, the higher the material and labor costs.
- Accessibility: Hard-to-reach ceiling spaces or concrete walls increase installation time.
- Network Complexity: Multiple floors, rack terminations, or integration with AV/security systems add cost.
- Permits & Code Compliance: San Jose building permits for low voltage wiring typically range from $150–$400.
- Testing & Certification: Professional certification adds $15–$30 per drop.
Labor Costs for Low Voltage Cabling in San Jose
The average labor rate for certified low voltage technicians in San Jose ranges from $85 to $120 per hour, depending on project complexity and company reputation. A Complete Guide for Reliable Connectivity
Typical breakdown:
- Installation & Termination: $60–$90/hr
- Network Testing & Certification: $25–$30/hr
- Project Management / Site Supervision: $100–$150/hr
