When planning a technology, security, or communications project, many property owners face the same question: should they hire an electrician or a low voltage wiring contractor?
The confusion is understandable. Both professionals work with wiring, cables, and building infrastructure. However, they perform very different jobs and hold different California licenses. Hiring the wrong contractor can lead to project delays, code compliance issues, unnecessary costs, and systems that fail to perform as expected.
For example, if you’re installing office internet, security cameras, VoIP phones, access control systems, or structured cabling, a traditional electrician may not be the right specialist. On the other hand, if you need electrical panels, outlets, lighting circuits, or power distribution, a low voltage electrical contractor is not the correct choice.
Understanding the distinction helps property owners, facility managers, and business owners make informed decisions before a project begins.
In this guide, we’ll explain what a licensed electrician does, answer the common question “what is a low voltage contractor,” and help you determine which professional is best suited for your project in Los Angeles.
What Does a Licensed Electrician Do?
A licensed electrician specializes in electrical systems that distribute power throughout a building. Their work typically involves systems operating at standard utility voltages such as 120V and 240V in residential and commercial properties.
In California, electrical contractors generally operate under a C-10 Electrical Contractor license issued by the California Contractors State License Board (CSLB).
Typical electrician services include:
- Electrical panel installation and upgrades
- Circuit breaker replacement
- Lighting installation
- Power distribution systems
- Electrical outlets and switches
- EV charger installations
- Backup generator connections
- Electrical troubleshooting and repairs
According to the California Contractors State License Board, C-10 contractors are authorized to install, maintain, and repair electrical systems that transmit or utilize electrical energy.
However, many property owners are surprised to learn that electricians typically do not specialize in:
- Ethernet cabling
- Structured cabling systems
- VoIP phone infrastructure
- Network wiring
- Security camera networks
- Access control systems
- Audio-video integration
- Data communications infrastructure
While some electrical contractors may offer limited technology-related services, these systems generally fall under the scope of a specialized low voltage wiring contractor.
What Is a Low Voltage Contractor?
If you’ve ever asked yourself, what is a low voltage contractor, the simplest answer is this:
A low voltage contractor designs, installs, and maintains communication, security, networking, and technology systems that operate at 49 volts or less.
In California, these contractors typically hold a C-7 Low Voltage Systems Contractor license issued by CSLB.
A qualified low voltage wiring contractor focuses on the infrastructure that powers modern communications and smart building technologies.
Typical services include:
- Ethernet wiring
- Structured cabling systems
- Fiber optic cabling
- VoIP phone systems
- Security camera installations
- Access control systems
- Alarm systems
- Audio-video systems
- Conference room technology
- Smart building infrastructure
- Wireless access point installations
- Telecommunications cabling
Unlike electricians, a low voltage electrical contractor specializes in data transmission rather than power distribution.
For businesses, a professional low voltage contractor in Los Angeles often becomes an essential partner for building reliable network infrastructure that supports productivity, security, and future growth.

In many modern commercial projects, both professionals may be required, but each performs a distinct role.
When Do You Need Both?
Many commercial construction and renovation projects require collaboration between an electrician and a low voltage wiring contractor.
For example, when building a new office:
- The electrician installs electrical panels, circuits, outlets, and power infrastructure.
- The low voltage electrical contractor installs network cabling, security systems, Wi-Fi infrastructure, and communications systems.
This coordinated approach ensures that power systems and technology systems are designed correctly from the beginning.
Projects that commonly require both include:
- New office construction
- Commercial tenant improvements
- Healthcare facilities
- Warehouses
- Schools and educational facilities
- Smart building deployments
Organizations investing in modern workplace technology often combine electrical services with specialized data cabling and smart building infrastructure to ensure long-term scalability.
