What Is a Low Voltage Contractor?

A low voltage contractor is a licensed professional who installs, maintains, and troubleshoots systems that operate on 50 volts or less. Unlike standard electricians who work on high-voltage power (120/240 volts for outlets and appliances), low voltage contractors specialize in:

Security and surveillance systems
Fire alarms and life safety systems
Structured cabling for internet and phones
Smart home automation and audio-visual setups

According to the National Electrical Code (NEC), low voltage wiring is considered “power-limited” and requires specific training and permits for safe installation.

Installing devices (cameras, alarms, AV equipment)
Integrating systems with existing infrastructure

3. Testing & Troubleshooting
