Cabling
Low-Voltage Wiring
Structured cabling infrastructure for data, voice, security, and AV systems — anything running at 50 volts or less, distinct from line-voltage electrical work.
Low-voltage systems include Ethernet, fiber, telephone, coax, access control, security cameras, intercoms, speakers, and AV distribution. The work lives at the boundary between IT and electrical — it requires no electrician's license in most places, but should still follow code and structured-cabling best practices.
Low-voltage cabling needs its own pathways and shouldn't share conduit with standard 120/240V electrical wiring — both because line voltage induces noise on data cables, and because code requires separation.
In commercial environments, low-voltage work is typically scoped separately from the electrical contract. The distinction matters when coordinating contractors — a general electrician is not usually a structured cabling installer.
