Electrician vs. Low-Voltage Work in Ohio?
No, not for standard low-voltage work. Ohio law exempts systems running under 50 volts, including ethernet cabling, doorbell wiring, security cameras, and most smart-home sensors, from electrical contractor licensing (Ohio Revised Code 4740.13(D)). You need a licensed electrician only when the job touches your home's line-voltage wiring: a smart switch replacing a wall switch, a new outlet, or anything connected to your electrical panel.
Do you need an electrician to install Ethernet cables?
No. Ethernet is a data cable carrying well under 50 volts, so it falls squarely inside Ohio's low-voltage exemption. A low-voltage installer, not a licensed electrician, runs ethernet drops, terminates the jacks, and tests the line. You can also run it yourself if you're comfortable fishing cable through walls; there's no license requirement for a homeowner doing their own work either.
What is Ohio's low-voltage exemption, in plain terms?
Ohio Revised Code 4740.13(D) says a person doing work limited to construction, installation, repair, testing, or maintenance of systems running less than 50 volts, specifically fire alarm, burglar alarm, cabling, tele-data, sound, communication, and landscape lighting/irrigation systems, is not required to hold an electrical contractor license for that work. In practice, that covers almost everything people mean by "low voltage": ethernet and network cabling, security camera wiring, doorbell wiring, speaker wire, and most smart-home sensor wiring.
The exemption has one limit worth knowing: a licensed contractor can also wire the "control wiring" for devices tied to their own licensed trade, as long as that control wiring runs under 25 volts. That's a narrow provision for licensed contractors working adjacent to their own systems, not a separate homeowner rule.
What is a low voltage electrician called?
Nobody in Ohio is required to be licensed as a "low voltage electrician" the way a line-voltage electrician is licensed, because the trade itself is exempt below 50 volts. The people doing this work are usually called low-voltage technicians, structured cabling installers, or security/AV installers, and many carry manufacturer or industry certifications (BICSI for cabling, for example) even though the state doesn't require a contractor's license for the work itself.
Do electricians do low voltage wiring?
Some do, some don't. A licensed electrician's license covers line-voltage work by default; whether they also do low-voltage cabling, cameras, or smart-home wiring depends on the individual contractor's scope of business, not a licensing requirement. Plenty of electricians choose not to take low-voltage jobs because the margins and tools are different from panel and outlet work. A dedicated low-voltage contractor typically has more day-to-day experience with cabling, cameras, and network gear specifically.
Where you DO need a licensed electrician
The exemption has real edges. These are line-voltage jobs and always require a licensed electrician:

- Smart switches and in-wall dimmers: these replace your existing wall switch and connect directly to line voltage, not just a low-voltage control signal.
- New electrical outlets: including an "in-wall power kit" outlet added behind a mounted TV.
- Panel-connected devices: smart thermostats or other devices wired directly into your electrical panel rather than a low-voltage control circuit.
- Any work inside your breaker panel: always licensed electrical work, no exceptions.
LumeCrew coordinates a licensed electrician for these portions when they're part of a larger job (a smart lighting project, for instance). That work is always described here as performed by a licensed electrician, not by LumeCrew directly.
Can you run low-voltage wire without conduit?
Often, yes, inside walls in residential construction, though local building code and the specific wire type (plenum-rated cable in some ceiling spaces, for example) can require conduit or specific cable ratings. This varies by jurisdiction and by where the run is located (open ceiling plenum vs. inside a finished wall), so check your local code office or ask your installer before assuming a bare-wire run is code-compliant everywhere in the house.
How much does a low voltage electrician charge per hour?
Since "low voltage electrician" isn't a separate licensed trade in Ohio, there's no state-set rate to point to. Low-voltage installer rates vary by market and job type; get a scoped flat quote for your specific job rather than comparing hourly rates across unrelated projects; see our structured cabling cost page for project-based ranges.
Who are some reputable commercial electrical contractors in Columbus, Ohio?
For line-voltage commercial electrical work, look for a contractor holding an active Ohio electrical contractor license through the Ohio Construction Industry Licensing Board and carrying current liability insurance. LumeCrew coordinates licensed electricians as part of low-voltage projects that cross into line-voltage scope; for a standalone electrical project, verify any contractor's license status directly with the state board before hiring.

FAQ
Is LumeCrew a licensed electrical contractor? LumeCrew coordinates the work rather than performing it. Low-voltage cabling in Ohio does not require a state electrical license, and when a job includes line-voltage work, the installer of record is a licensed electrician.
Does low-voltage work need a permit in Ohio? Usually not at the state level for cabling under 50 volts, but municipalities set their own rules, and line-voltage portions follow standard permit practice. The installer handling your job confirms local requirements during scoping.
Can I run my own ethernet cable and have a pro terminate it? Yes. Plenty of homeowners pull their own cable and bring in a professional for termination, testing, and certification. Expect the pro to test every run before calling it finished.
