Structured Cabling Permit Requirements in Guilford County, North Carolina

Quick Answer: Guilford County generally does not require permits for low-voltage structured cabling installations that operate under 50 volts and use Class II or Class III power supplies. However, permits may be required when work involves fire-rated assembly penetrations, new electrical circuits, or commercial construction projects. All installations must comply with NEC Article 800 and industry standards.

North Carolina Low-Voltage Exemption Conditions

Per North Carolina electrical code, low-voltage systems may be exempt from licensed contractor requirements when:

• Control circuit and power supply is Class II or Class III per NEC
• System operates at voltage not exceeding 50 volts
• Meets provisions for sound-recording and similar equipment in NEC
