Structured IT Cabling Design & Installs FAQ

What is meant by structured cabling?

Structured cabling refers to a standardized wiring infrastructure made up of organized subsystems — including copper and fiber optic cabling, patch panels, and connecting hardware — that supports data, voice, and video communication throughout a building or campus. LJ Electric designs and installs structured cabling systems for schools, municipal buildings, multi-unit housing, and commercial facilities across Connecticut, ensuring dependable connectivity and long-term scalability.

What are the 6 components of structured cabling?

The six key components are Entrance Facilities, Equipment Room, Backbone Cabling, Telecommunications Room, Horizontal Cabling, and Work Area. Each plays a critical role in maintaining performance, organization, and flexibility. LJ Electric’s low-voltage specialists ensure that every component is professionally designed, labeled, and tested to meet industry standards and local building codes across Connecticut.

What is the difference between structured and unstructured cabling?

Structured cabling follows industry standards (ANSI/TIA-568, ISO/IEC 11801) to create a logical, scalable, and easy-to-manage network. In contrast, unstructured cabling lacks standardization, making it harder to maintain and troubleshoot. With decades of experience in commercial and municipal projects, LJ Electric helps clients transition from outdated or unorganized systems to structured, future-ready network infrastructure that minimizes downtime and supports growth.

Why would you use structured cabling?

Structured cabling systems offer scalability, reliability, and efficiency, making them ideal for businesses planning for growth or technology upgrades. They allow for easy expansion, minimal downtime, and cleaner installations. LJ Electric designs and installs structured cabling systems that support advanced communications, security cameras, access control, and data networks for Connecticut businesses and institutions that rely on dependable connectivity.

Are low voltage systems totally safe?

While low voltage systems operate below 100 volts and are generally safer than standard electrical wiring, they still require proper installation and protection to prevent fire hazards or electrical faults. LJ Electric’s licensed technicians are trained to follow all NFPA and NEC standards, ensuring that every low-voltage installation — from data lines to security systems — is safe, compliant, and built to last.

Are there building codes for low voltage?

Yes. The National Electrical Code (NEC or NFPA 70) regulates all low-voltage wiring in the U.S., covering installation methods, materials, and safety protocols. LJ Electric ensures all structured cabling and low-voltage systems in Connecticut commercial and public facilities are fully compliant with current NEC and local code requirements, passing inspections the first time.

How long can you run a low voltage wire?

The safe length of a low-voltage wire depends on its gauge and load — typically 60 feet for 16/2 wire, 100 feet for 14/2, and 200 feet for 12/2 with standard wattage. LJ Electric evaluates each system’s voltage drop and power needs to design efficient, code-compliant wiring layouts that maintain performance across your entire property.
