Low voltage electricians work around and in residential and commercial structures installing, upgrading, repairing, and maintaining low voltage electrical systems.

As a profession, low voltage electrician occupation exists since the early 20th century.

Originally, they were installing, maintaining, and repairing leadline telephone networks.

A hundred years later, this occupation became fully mature since multiple low voltage systems are now common.

They include CCTV systems and other security devices as well as broadband cabling and on-site fiber optics, and more.

In terms of licensing, low voltage electricians face countless state regulations.

However, the professional techniques, guidelines, and tools are regulated by the National Electrical Code (NEC).

Low voltage electricians with proper credentials can count on growing salaries, stable job environment, and challenging and diverse daily tasks.

Training and License Requirements

License and training requirements can differ depending on the state, county, and city given how on what kind of requirements the licensing jurisdiction sets.

A comprehensive state-by-state directory of licensing requirements for low voltage electricians is provided by the NECA (National Electrical Contractors Association).

It’s divided by occupation, e.g., alarm technician, telecommunication technician, etc.

This directory is briefly summarized below.

Low voltage electricians can obtain a license in three common ways:

  • Low voltage electrical work can be included in the residential electricians’ category by the licensing jurisdictions.
    In this case, you will have to follow the residential electrician licensing path.
    It includes 4-6 years of an apprenticeship followed by an exam.
    Then, 2-4 years as a journeyman plus examination, and master electrician.
    At this level, you may have to pass an exam to obtain a contractor’s license should you need one.
  • In some jurisdictions, low voltage electricians are classified as a separate licensing category.
    The licensing and training requirements, in this case, don’t take as much time as residential electricians.
    This path also includes the standard licensing process with apprentice-journeyman-master levels.
  • In some jurisdictions, low voltage electricians can be licensed according to their individual roles.
    It implies a different licensing process for each specialty, such as fire alarm technicians, security alarm technicians, phone line technicians, and so on.
    The amount of time necessary for such licensing is the least compared to other paths and can be completed within just a few months.

Low voltage electricians may not be regulated in some jurisdictions at all, while in others, they may have to meet additional requirements not included in any of the standard processes.

To find out how exactly the licensing process is regulated in your area, check with the local chapter of the IBEW or the regulatory agency of your jurisdiction.
