If you are weighing low voltage technician vs. electrician, you are really choosing between two kinds of wire. Electricians install the conductors that carry power: feeders, branch circuits, panels, motors. Low voltage technicians install the cabling that carries signals and small amounts of power: data networks, cameras, access control, intercoms, audio-visual systems, and in many places fire alarm. Both jobs pull cable through buildings, and both are in demand. But the paths, the licenses and the ceilings are different, and the differences matter more than the job titles suggest.
This guide compares the two on pay, licensing, daily work and long-term options, using federal wage data and real state rules rather than averages from job boards.
What a low voltage technician does vs. an electrician
The Bureau of Labor Statistics describes electricians as the people who install, maintain and repair power, communications, lighting and control systems. In practice, a licensed electrician spends most of the day on line-voltage work: setting panels, running conduit, pulling feeders, terminating devices, and troubleshooting circuits that can kill you if you get careless.
"Low voltage technician" is not one federal job category. It is a label that covers several. The two closest matches in federal data are:
- Security and fire alarm systems installers. According to O*NET, they mount control panels, door contacts, sensors and cameras, wire them together, test backup batteries and sirens, and program keypads. Many also meet with clients and write up estimates.
- Telecommunications equipment installers. This group covers technicians who install and repair communications equipment and wiring, including in customer buildings. Common titles include network technician and broadband technician.
Structured cabling installers, AV integrators and building automation techs fall in the same family. The common thread is that the circuits are power-limited. The Electronic Security Association's model licensing language describes this work in National Electrical Code terms: Class 2 and Class 3 remote-control, signaling and power-limited circuits, plus fiber and communications cabling. It does not use a single voltage number.
What the day actually looks like
An electrician on a commercial job might bend and hang conduit all morning and pull wire all afternoon. The material is heavy, and the work often involves a lift, a ladder and a lot of measuring.
A low voltage tech on the same building is more likely to be hanging J-hooks, pulling bundles of Category cable, punching down jacks and patch panels, mounting cameras, and then spending real time at a laptop programming panels, testing links or setting up an access-control system. Less weight, more terminations, more configuration. If you enjoy the "make it talk to the network" part of a job, that is a meaningful difference.
Pay compared: the gap is smaller than you think
Many people assume electricians earn far more. Federal median pay says the gap is small at the middle of the market. These are national medians from the BLS, May 2025 data, as published on the BLS and O*NET pages linked here.
| Occupation (federal title) | Median hourly | Median annual | Projected outlook, 2025–35 |
|---|---|---|---|
| Electricians | $30.38 | $63,190 | 9% growth, about 72,700 openings a year |
| Security and fire alarm systems installers | $28.88 | $60,070 | Much faster than average (7%+) |
| Telecommunications equipment installers (except line) | $30.72 | $63,890 | Declining (-1% or lower) |
Three things stand out:
- The middle is close. A median alarm installer earns roughly $3,000 a year less than a median electrician. A median telecom installer earns slightly more.
- The top end favors electricians. The BLS reports that the highest-paid 10% of electricians earned more than $108,510. Electricians also have more paths to that top end: industrial maintenance, government work and contracting.
- Industry matters. For electricians, BLS lists a government median of $79,820 and a manufacturing median of $74,550, compared with $61,570 at electrical contractors. Where you work moves pay as much as which trade you pick.
Job counts are also very different. The BLS counts 821,000 electricians. O*NET counts about 86,300 security and fire alarm installers and 143,100 telecom installers. More jobs means more employers, more locations and more ways to change jobs without changing trades.
Licensing: where the two paths really split
Most states require electricians to pass an exam and hold a license, and the BLS notes that the requirements differ from state to state. A journeyman electrician license usually means about four years of documented hours plus a code exam. Once you have it, it covers nearly all electrical work, including low voltage in most places.
Low voltage licensing is a patchwork. Some states have a separate limited-energy license. Some fold low voltage into the electrical license. Some do not license it at the state level at all, which leaves it to cities. Two real examples show how far apart the rules can be.
Washington: a 4,000-hour specialty certificate
Washington's Department of Labor & Industries runs a specialty electrician system. The 06 limited energy system certificate is a 4,000-hour specialty that also requires 48 hours of classroom education. The general journey level (01) certificate requires 8,000 hours and 96 classroom hours. Trainees in 4,000-hour specialties must be supervised at least 75% of the time. So in Washington, a low voltage career is still a licensed electrical career. It just takes half the hours.
California: a contractor classification capped at 91 volts
California's Contractors State License Board has a C-7 Low Voltage Systems classification for energy-limited systems that do not exceed 91 volts. The scope covers telephone, sound, cable TV, closed-circuit video, satellite dishes, instrumentation and temperature controls, and low-voltage landscape lighting. Low-voltage fire alarm is specifically left out. Note that this is a contractor license for the business, not a certification for individual workers.
Industry certifications
Low voltage hiring often relies on industry credentials more than state licenses. One common entry-level credential is BICSI's Installer 1. According to BICSI's badge description, it covers the basics of installing communications cabling in commercial buildings: pulling, terminating and testing copper and coax, along with codes, blueprints and telecom room equipment. It requires an application and a passed exam, and the listing shows no work-experience requirement. Fire alarm specialists often add separate fire alarm credentials later.
How long each path takes to start
This is where low voltage has its biggest advantage. According to the BLS, most electricians go through a four- or five-year apprenticeship, with about 2,000 paid hours on the job each year plus classroom training. You earn while you learn, but the license comes at the end.
Low voltage work usually starts faster. In O*NET's survey of security and fire alarm installers, 49% of respondents said a post-secondary certificate is required and 41% said a high school diploma is enough. O*NET also describes the training as typically one to two years. In a state like Washington, the licensed version still takes 4,000 hours, which is about half of the journey-level requirement.
Low voltage technician vs. electrician: which fits you?
| If this sounds like you... | Lean toward |
|---|---|
| You want the widest set of jobs and the most portable license | Electrician |
| You like networking, programming panels and getting systems to work together | Low voltage |
| You want to start working with a credential in under two years | Low voltage |
| You want to run your own shop someday doing any kind of electrical work | Electrician |
| Your back or knees will not tolerate years of heavy conduit and feeder pulls | Low voltage |
| You want the top-end pay of industrial, government or contracting work | Electrician |
| You already have IT or AV experience | Low voltage, possibly crossing over later |
Can you switch between them later?
Crossing over is common, but it is easier in one direction. A journeyman electrician can usually do low voltage work under the same license. Some may still need a vendor certification to program a specific panel or camera system.
Going from low voltage to electrician usually means starting a power-side apprenticeship or trainee path. Your low voltage hours may or may not count. In Washington, for example, the 01 journey level certificate allows no more than 4,000 of its 8,000 hours to come from 4,000-hour specialties. So limited-energy experience can count for up to half of the journey-level hours, but not all of them.
Many low voltage techs also like the security and fire alarm side because it includes service contracts: inspections, battery testing and repairs. That steady service work tends to continue whether or not new construction is busy. Telecom installation, by contrast, is projected to shrink slightly over the next decade, so if you go low voltage, lean toward security, life safety and building systems over pure telecom.

The bottom line
Choose electrician if you want the license that opens the most doors, a higher pay ceiling, and the option to contract any kind of work later. It takes longer, and the work is harder on your body.
Choose low voltage if you are drawn to networks, cameras, access control or fire alarm, want to earn sooner, and are fine with a credential that covers less ground. Median pay is close to an electrician's. Just check your state's rules first, and favor security and life-safety work over telecom.
