Low voltage electrician
Low-voltage work covers the wiring that carries signals and small power: network, security, AV, thermostats and doorbells.

The short answer
A low voltage electrician installs wiring that runs below line voltage, such as network cable, security and camera systems, thermostats, doorbells and lighting controls. Many states license low-voltage work separately from general electricians. The main safety rule is separation: low-voltage cable must not share boxes or raceways with line-voltage wiring unless listed barriers are used.
What the job includes
Pulling cable, terminating jacks and devices, mounting equipment, and powering it from a listed Class 2 transformer or power supply. Line-voltage connections for those supplies are electrician work.
Examples: doorbell wiring, thermostat wire for a heat pump, PoE cameras, low-voltage under-cabinet lights.
Licensing varies
Some states issue a separate low-voltage or limited-energy license; others fold it into the general electrical license; a few do not license it. Check your state board: how to check an electrician license.
NEC Article 725 covers power-limited circuits.
Permit, time and what changes the price
Many jurisdictions exempt small low-voltage jobs from permits; larger systems may need one.
Price drivers: cable runs through finished walls, number of drops, equipment, and attic or crawlspace access. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Separation and fire rules
Keep low-voltage cable away from the cover of the electrical panel and out of boxes that hold outlets or switches. Induced noise and the risk of line voltage reaching a data or security line are the reasons the code separates them.
Low-voltage cable through fire-rated walls must be firestopped. Cable left above ceilings must be supported, not laid on tiles.
Power-over-Ethernet and lighting control are growing fields, so ask about experience with the system you are buying.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
